for many people in britain there has been no avoiding the jet stream' s effects. meteorologists say its high winds are responsible for bringing two ferocious atlantic storms to northern britain .
the latter phase of the flow evolution also included some modifications within the interior of the wag. as the atlantic jet deflected more predominantly into the northeast, some atlantic water from the strait entered directly into the wag, in agreement with earlier studies [ 8 ], [ 37 ], [ 38 ]. a small relatively weak cyclonic eddy was formed within the center of the gyre, possibly due to the instability of the jet. another stronger cyclonic eddy, located on the southern side of the gyre, may have originated from the closing branch of the wag well before it reached the south coast by the strong curvature and westward advection of the jet. this type of gyre structure offered a variant of the atlantic jet - wag system [ 10 ] .
airbus believes the hypersonic jet could have both civilian and military applications. in civilian trim, the craft could serve as private jet or as an airliner with room for 20 passengers. in military trim, the jet could serve as a hypersonic transport for commandos or as a reconnaissance plane like the sr71 blackbird .

i used to think i’d never meet an aeroplane disaster movie i didn’t like, but now i’m not so sure. this film is... weird... and not in a good way. in fact, i’m not sure that jet over the atlantic isn’t the universe’s way of punishing me for getting too much of a kick out of films about bombs on planes .
the rest of jet over the atlantic is very strangely constructed: it keeps feeling like bits are missing, as if they chopped out random scenes to make it shorter. it is also profoundly dishonest. while the random action of the poisonous fumes, which affect some people more than others, is actually likely, the fact that no - one dies but minor characters – minor spanish characters – is pretty damn tacky .
but what about flights over the ocean where there are no navigational aides? aircraft follow tracks that are made up of predetermined sets of latitude and longitude coordinates across the ocean. for example, these are the north atlantic tracks (the same general principle applies to the pacific ocean as well) .
however, the intriguing thing about this scenario is that it parallels that offered by the other aeroplane disaster movie of 1959, jet storm, wherein a grieving father plots to blow up a plane on which the man who killed his daughter in a hit - and - run is travelling, killing not only the guilty party but himself and everyone else in the process. jet over the atlantic was, as i say, an american production shot in mexico; jet storm is british. the two films were released within two months of one another in their respective countries, and must have been in production at around the same time. it is hard to think that one could have influenced the other, which makes this a peculiar coincidence indeed .
the surface distribution of the vertical component of the relative vorticity normalized by the planetary vorticity at day 120 (fig. 3c) very closely resembled the surface flow and density fields (fig. 3a, b). we recalled that the absolute value of this ratio is an estimation of the rossby number; thus, it characterizes the degree of nonlinearity of the flow field. the circular path of the atlantic jet around the wag was related to the generation of an anticyclonic relative vorticity (fig. 3c) due to the upward tilting of the interface and compression of the upper layer flow along the strait [ 10 ], [ 32 ]. the jet around the gyres was surrounded by several cyclonic eddies with positive relative vorticity and dense water patches. the eddy closest to the exit section was associated with the strong density gradient that set a strong vertical geostrophic shear and thus the generation of cyclonic vorticity [ 10 ]. this cyclonic vorticity deflected the atlantic jet towards the northwestern coast. further downstream, the outer flank of the jet generally featured a strong relative vorticity gradient from negative (around −0. 5 on the inner side) to positive (up to + 0. 5 on the outer side) in agreement with previous observations [ 39 ]. the rossby number reached values over 0. 5 along the jet, which indicated its nonlinear character and the relevance of ageostrophic motion .

but it’s peculiar for another reason. both of these films were, self - evidently, inspired by the real - life bombing perpetrated by jack graham, who blew up a plane in order to murder his mother for her (non - existent) insurance money. yet although this actually happened, both jet storm and jet over the atlantic shy away from the sheer cold - bloodedness of it, offering instead bombers who have been driven insane by the death of a child, and who are suicidal as much as homicidal: bad enough, but not nearly as bad as the reality .
computer model guidance suggests that a u. s. landfall is within the realm of possibility, with a turn out into the north atlantic also still on the table .
the jet - front system was set up and maintained by the flow and stratification characteristics prescribed at the western inflow section. the atlantic jet entered from the strait of gibraltar at a fixed rate in the form of a buoyant surface intensified current in the absence of sub - inertial (weekly to monthly) variability in response to changing atmospheric pressure and wind patterns of the region. the jet remained stable and coherent without mesoscale - submesoscale variability in response to the frontal instabilities [ 5 ], [ 7 ], [ 12 ], [ 22 ], [ 37 ], [ 38 ], [ 54 ], [ 57 ], [ 58 ] .
what this means is that the weather pattern across the u. s. next week will probably feature a wavy jet stream. how this jet stream pattern interacts with irma will be a big question that forecasters hope to answer, since an east coast trough could help to sweep the storm out to sea .
a three dimensional biophysical model was employed to illustrate the biological impacts of a meandering frontal jet, in terms of efficiency and persistency of the autotrophic frontal production, in marginal and semi - enclosed seas. we used the alboran sea of the western mediterranean as a case study. here, a frontal jet with a width of 15–20 km, characterized by the relatively low density atlantic water mass, flows eastward within the upper 100 m as a marked meandering current around the western and the eastern anticyclonic gyres prior to its attachment to the north african shelf / slope topography of the algerian basin. its inherent nonlinearity leads to the development of a strong ageostrophic cross - frontal circulation that supplies nutrients into the nutrient - starved euphotic layer and stimulates phytoplankton growth along the jet. biological production is larger in the western part of the basin and decreases eastwards with the gradual weakening of the jet. the higher production at the subsurface levels suggests that the alboran sea is likely more productive than predicted by the satellite chlorophyll data. the mediterranean water mass away from the jet and the interiors of the western and eastern anticyclonic gyres remain unproductive .

this is, simultaneously, the most frustrating and the most interesting thing about jet over the atlantic. the screenplay never lets us in on what happened to laurie, or why sir robert thinks he was responsible for her death; though for what it’s worth, lady leverett shakes her head vehemently when he accuses himself. since his guilt and grief are about to send sir robert into full - on angel - of - death mode, it would be kind of nice to know .

during the subsequent month (fig. 2b), the anticyclonic eddy along the sw - ne - oriented african coast was detached and gradually dissipated within the basin. the anticyclonic gyre at the gibraltar exit section expanded gradually northward. the atlantic jet entering the basin as a zonal jet fed this gyre and flowed around it to the south coast. it then proceeded mainly eastward, whereas a weak branch turned westward to close the gyre circulation. later (fig. 2c), the orientation of the atlantic jet shifted gradually towards the northeast and the anticyclone near the gibraltar exit section evolved to form a well - established wag structure covering the basin up to 3. 5°w longitude. similarly, the coastal anticyclone to the east of cape tres forcas expanded offshore (fig. 2b) and evolved into a meridionally elongated eag between 2. 5°w and 1. 0°w (fig. 2c). the meanders of the northern coast were eventually detached and made the westward boundary current along the spanish coast that is less well - depicted due to its interaction with the gyres. the region between the wag and eag was occupied by a cyclonic circulation (fig. 2c) .
according to patentyogi' s deepak gupta, this means the airbus jet could make the trip from london to new york in just one hour. that' s a significant improvement over the 3 1 / 2 hours it took for the now retired mach 2 concorde to make the same trip. the concorde was a joint venture between airbus' two predecessors, france' s aerospatiale and british aerospace .
the surface density distributions accompanying the circulation fields in fig. 2a–d show how the initial horizontally uniform dense water mass (∼27. 8 kg m −3) was freshened and spatially structured up to the density range 27. 0–27. 5 kg m −3 by means of the steady inflow of atlantic water. at day 120, the atlantic jet attained a surface current speed of 0. 7 m s −1 and a density of 26. 5 kg m −3 near the gibraltar exit section (fig. 3a, b). they were modified to the ranges of 0. 5–0. 6 m s −1 and 26. 5–26. 8 kg m −3 around the wag, whereas the surface density of cyclonic eddies inside the wag exceeded 27. 0 kg m −3. the atlantic jet was separated from the ambient water mass by a well - marked narrow front identified by the density variations between 26. 8 and 27. 3 kg m −3 around the wag. however, it appeared to lose much of its initial momentum and weakened by half around the eag and further eastward along the coast (fig. 3a). as the jet weakened, its density increased to the range 27. 0–27. 4 kg m −3 along the western side of the eag and 27. 2–27. 4 kg m −3 along its eastern side, with respect to an interior density of ∼27. 1 kg m −3. the southward spanish current flowing along the eastern side of the eag attained a speed of approximately 0. 2 m s −1 and separated the alboran surface water mass from the rest of the basin further east (fig. 3b). the weakening of the atlantic jet eastward was consistent with the gradual reduction of the zonal density gradient towards the eastern side of the model domain .
the 172 is still rolling off textron aviation’s production lines in wichita, kansas, which means that you don’t have to buy a secondhand model should you want one of your own. so if you live in the uk or europe, you have two options – partially disassemble the aircraft and pack it into shipping crates, or get it flown over the vast expanse of the north atlantic .
up on issuing from the gibraltar strait, the atlantic jet deflected northeastward, looped around the wag and proceeded eastward in the form of a boundary current along the north african shelf break / slope topography. its meandering around the wag was imposed mainly by the generation of anticyclonic relative vorticity due to the upward tilting of the interface and compression of the upper layer flow along the strait. another intense meander developed along the african coastline in response to perturbations developed in the boundary current triggered by the coastline irregularities and the topographic beta effect. in our model, the continuous supply of a fixed rate of atlantic water mass from the gibraltar strait caused the wag to cover the entire western alboran basin in its mature state. in reality, its growth is modulated by the subinertial variability of the upper layer transport across the strait and by the impacts of the regional atmospheric conditions on the alboran sea circulation system. despite such variability, the northeastern expansion of the wag and the presence of its front near the northern coast is a persistent feature of the atlantic jet - wag system as it is corroborated, for example, by the seasonal surveys carried out in 1996–97 in this region [ 14 ], [ 50 ]. the mature state of the flow structures developed in our simulation resembles the one observed during december 1996 [ 9 ] .

the performed simulation from the biophysical model linked the efficiency and persistency of the autotrophic frontal production to the meandering atlantic jet of the upper layer circulation system of the alboran sea. the simulation started initially with nutrient - starved conditions, it excluded the horizontal nutrient transport from the gibraltar strait and also the likely modifications of ageostrophic vertical motion from other physical processes, such as wind - driven vertical advection and turbulence, and enhanced buoyancy - induced mixing by strong winter cooling. identifying the relative contributions of all of these processes remains to be explored in future studies .

a model was created to assess the performance of an ads - b receiver scheduled to be launched on the canx - 7 nanosatellite. the model takes into account neutral atmosphere and ionospheric effects, aircraft - satellite geometry, and antenna radiation patterns. the region of interest for this study is the north atlantic region as this area presently uses procedural air traffic services instead of radar - based services that are used over land. it is also relatively quiet in the 1090 mhz frequency band .
the average annual mean primary productivity of the alboran sea exceeds 100 gc m −2 yr −1 [ 11 ], comparable to those observed in mesotrophic systems and among the highest within the oligotrophic mediterranean sea. a major part of the plankton productivity (> 300 gc m −2 yr −1) appears to be associated with the atlantic jet, as documented by observations performed along the frontal zone around the wag [ 12 ] – [ 14 ], the eag [ 6 ], [ 15 ] – [ 17 ] and along the algerian coast [ 18 ], [ 19 ]. the link between the frontal jet structure and phytoplankton production is so robust and persistent that it may appear in the form of a narrow zone of relatively high chlorophyll concentrations around the anticyclonic gyres even in the long - term mean winter ocean color data (fig. 1) .

the roles played by different dynamical processes on the biogeochemical characteristics of the alboran sea have not yet been quantified. excluding the models that treated the alboran sea as a part of the western or the whole mediterranean sea [ 20 ], [ 21 ], the only coupled physical - biochemical modeling effort dedicated to the biochemical - physical interactions in the alboran sea [ 22 ] simulated the annual plankton production cycle in reasonable agreement with the observations system, but it did not explore the specific role of frontal dynamics. following the objectives of the socib (balearic islands coastal ocean observing system) strategic plan [ 23 ], the present process study puts forth the meandering frontal jet to control the first order dynamics of the physical - biological interactions governing the observed biological production characteristics of the alboran sea. the individual roles of other physical factors (such as wind, strong winter turbulence mixing, and modulation of the atlantic jet by tidal and subinertial variability within the gibraltar strait, etc .) were not addressed here and were left for a future study .

the vertical density structure of the circulation field is depicted by fig. 4a for the transect that crosses the wag diagonally and then extends zonally across the eag towards the algerian basin (see fig. 2d). it identified the low density anticyclonic gyres with isopycnals in the range of ∼27. 0–28. 0 kg m −3 deepening towards their centers within the upper 100 m layer and to 28. 5 kg m −3 between 150–200 m. the latter represented the interface between the atlantic and mediterranean water masses, in agreement with previous observations [ 8 ], [ 14 ]. two frontal zones for both the wag and the eag were identified by the upward sloping isopycnals greater than 27. 5 kg m −3 towards the surface. the vertical structure of the jet accompanying these well - marked narrow frontal zones extended to 200 m with a gradual reduction in its strength from 0. 7 m s −1 at the surface around the wag and 0. 3–04 m s −1 elsewhere (fig. 4b). as stated previously, the strength of the jet and its vertical dimension reduced eastward with the almeria - oran front being the weakest one .
to get off the ground, the craft will use two turbojets mounted under the fuselage as well as a rocket motor mounted in the rear. as the airbus lifts off the runway, it will climb vertically like the space shuttle. right before the jet reaches the speed of sound, the turbojets shut down and retract into the belly of plane — leaving only the rocket motor to guide it up to an altitude of more than 100, 000 feet .

the wind stress and the total heat flux at the surface were set to zero to exclude the likely effects of wind - and buoyancy - induced vertical mixing, as well as the coastal upwelling / downwelling events on plankton production. the nitrate content of the initial nitrate profile within the upper 100 m layer was also set to zero in order to minimize the contribution of initially available nitrate for supporting plankton production. in addition, the advection of biological fields along the gibraltar strait were switched off to exclude the lateral supply of nutrients and biogenic material from the gibraltar strait. under these conditions, plankton production within the alboran sea originated solely from the diapycnal advective and diffusive fluxes provided from deeper levels by the quasigeostrophic and ageostrophic processes. in the subsequent section, we demonstrated that the ageostrophic processes dominate within the frontal jet and lead to strong plankton production, whereas the quasigeostrophic processes predominated away from the immediate vicinity of the frontal jet .

the pilot never returned to the cockpit, and now the co - pilot begins to feel woozy. he calls out to the navigator, then looks around to find him slumped over his instruments – dead. he reports in to new york, returns to his seat – and puts the plane on auto - pilot ...
for the jet stream, the storms can function as an injection of steroids, causing it to amplify and contort itself into large north - south undulations. these waves, known to meteorologists as ridges and troughs, get carried downstream like ripples in a pond, affecting weather in alaska and the continental u. s .
the sole director of pargav is oliver hylton, one of hintze' s closest aides and the manager of his charitable foundation that paid the donations to atlantic bridge. hylton has said he was
naive
to sign the documents that allowed werritty to create pargav, which also sought donations from private equity boss jon moulton and companies linked to the defence industry .
according to airbus, much of the plane' s aerodynamics are designed to limit and reduce the sonic boom it will create when it reaches supersonic speed. in the 1970s, the concorde was beset by complaints of sonic booms and noise pollution created by its four rolls - royce olympus turbojet engines. consequently, it was prevented from operating over land .
when he shares his ghost stories, lore’ s host aaron mahnke prefers a slow burn over splattering blood. unfolding with campfire solemnity, lore is a pagan ceremony and religious sacrament all at once. mahnke adopts silence as his canvas while delivering his monologues, austere readings that linger like no other horror podcast you’ll find. and it’s no wonder that lore discovered such a large audience: unlike so much horror that needs over - the - top viscera to scare you, this podcast leans on history—folklore, myth, the stuff people once thought were true—to tell its tales .
during his flight, khrushchev radioed greetings to sweden, norway, iceland and canada. another russian jet - a tu - 104 - sped ahead of him carrying soviet dignitaries, headed by foreign trade minister v. m. vinogradov. it landed at andrews at 10: 49 a. m .
flights enter and exit the track via a pair of waypoints on either side of the ocean so that all flights are properly aligned and air traffic control can estimate their position over the ocean correctly. you can even view each day’s nat tracks with a gold or business subscription to see which tracks are active and how busy they are .
stafford finds his fellow officers out on the tarmac. they are accompanied by a certain handcuffed individual who we recognise as goon # 1, and who speaks bitterly about, “that stoolie! ” the prisoner is taken over to the ambulance that is to transport mattoon, to identify him. instead he helpfully exclaims, “that ain’t the guy that squealed! that’s the chump we framed! ”
saudi - born bomb - maker ibrahim hassan al - asiri, believed to be a member of aqap, was also said to be behind a powerful bomb hidden in printer ink cartridges which was intercepted at a uk airport en route to the us in 2010, where it was timed to detonate over the east coast .
the wag grew further toward the northern coast and eastward during the rest of the integration period (up to day 120) (fig. 2d). the steady growth was related to the continuous supply of the atlantic water mass at a steady rate. the eag expanded meridionally and towards the wag due to its interaction with a transient meander that developed off the cape tres forcas. therefore, both gyres tended to cover the entire meridional extent of the basin during their mature states. the spanish boundary current proceeded mainly southward, crossing the basin near the eastern flank of the eag and joined the algerian coastal current. this southward current, together with the eastern flank of the eag, formed the adjacent almeria (spain) –oran (algeria) front representing the eastward limit of the alboran sea circulation system [ 6 ] .
automatic dependent surveillance - broadcast (ads - b) is an air traffic surveillance technology in which aircraft transmit position and identification. the development of space - based ads - b will allow precise control of aircraft in areas that are not covered by radar, such as oceanic regions and high latitudes. the royal military college of canada has developed a spaceborne ads - b receiver scheduled to fly on the canadian advanced nanospace experiment - 7 (canx - 7) satellite. the payload is planned to collect data over the north atlantic region, which will then be compared to truth data provided by air traffic services. a model was created to determine power levels arriving at the satellite to provide confidence in the ads - b receiver and antenna proposed for canx - 7. the model takes into account neutral atmosphere and ionospheric effects, aircraft - satellite geometry, and antenna radiation patterns. a simulation was run by inserting real aircraft data from the north atlantic track system into the model and placing the satellite at altitudes of 400, 600, and 800 km. results of the simulation indicate that power received at the satellite, ranging between −98. 5 dbm and −103 dbm for the selected altitudes, will be sufficient to successfully conduct the mission .
answer: civilian radar ends about 200 miles from the coast. a new york - to - london flight is an average of seven hours, and the portion when it' s over the ocean and out of radar contact is four hours. (these are very approximate figures and intended to show that more than half of the flight is out of radar. )
it is too early to tell which path lies ahead for hurricane irma, but it has already become a
major hurricane ,
of category 3 intensity or greater, and has a chance to get even stronger during its westward march over labor day weekend and into the first week of september .
the available in situ observations may support the fact that the model replicated the dominant mechanism underlying plankton productivity in the region. for example, observations performed along a meridional transect extending from the spanish coast to the center of the wag during july and december 1996 [ 14 ], [ 50 ] identified the frontal zone of the atlantic jet bordering the northern flank of the wag with relatively high geostrophic currents up to 0. 75 m s −1 and chlorophyll concentrations up to 3 mg l −1 compared to concentrations less than 0. 5 mg l −1 within the gyre interior. a similar survey performed during may 1998 [ 13 ] reported even higher chlorophyll concentrations up to 6 mg l −1 within the frontal jet zone. the may 1991 observations [ 26 ] along a north - south transect crossing the aeg meridionally also identified the frontal zone at the northern periphery of the eag by the upsloping of the nitracline, higher concentrations of chlorophyll - a, and particular organic nitrogen with respect to adjacent waters. as in the present study, these features were explained qualitatively in terms of the cross - frontal secondary circulation [ 15 ], [ 26 ]. moreover, the primary production along the almeria - oran front on the eastern flank of the eag was found to be 2. 5 times higher when compared to the more oligotrophic surrounding waters during the same observations [ 55 ]. they were also supported by 10 to 100 times higher vertical particle fluxes measured at 100 m and 300 m depths [ 56 ]. in situ measurements [ 16 ], [ 17 ] have also detected anomalously high chlorophyll - a concentrations associated with the almeria - oran front along the eastern flank of the eag .
american student eryk salvaggi, 35, who was due to travel on a virgin atlantic flight to boston this evening, said: ‘we had to go through the same process as usual, taking belts off, electronics out of bags, no large amounts of liquids and stuff, but the security guys were paying a lot of attention to everyone' s bags and items as they went through the scanners .
in the case of the fidget spinner, the temporary victory of joining in the commentary also offers succor. in an uncertain global environment biting its nails over new threats of economic precarity, global autocracy, nuclear war, planetary death, and all the rest, the fidget spinner offers the relief of a non - serious, content - free topic that harms no one. at a time when so many feel so threatened, aren’t handheld, low - friction tops the very thing we fight for ?
most literary podcasts adopt a familiar highbrow voice, but esquire classic makes english lit conversational. each episode sees the show reexamine one great piece from the magazine, poring over all the insider details: what susan orlean was thinking when she profiled a 10 - year - old boy, or why richard ben cramer was the perfect foil for ted williams. by interweaving readings of the essays with conversations between the host and someone close to the piece (usually a writer or editor), the podcast contextualizes the making of essential literature.
