A winter storm early: Stream jet stream combines air travel; Virgin Atlantic Flight 8 reaches 801 mph



On Monday night, the 35,000 feet above the New York City area, known as the jet stream, clocked in a blazing 231 mph. It is the fastest jet stream recorded since 1957 for the National Weather Service in Upton, New York – breaking the old record of 223 mph, according to NWS forecaster Carlie Buccola.

This air has provided turbo boost to commercial passenger airplanes along with for ride. With the help of this fast tailwind, Virgin Atlantic Flight 8 from Los Angeles to London hit what could be a high-speed record for a Boeing 787: 801 mph in Pennsylvania at 9:20 p.m. Monday night.

"Wow, that's fast," said a Boeing spokesman at CBS News via email. But this is not something that the airline produces, so they can not confirm whether the 801

mph is a record.

"The typical cruising speed of the Dreamliner is 561 mph," correspondent of CBS News's correspondent Kris Van Cleave. "The previous record for 787 was 776 mph set in January 2017 by a Norwegian 787-9 flying from JFK to London Gatwick. This flight has set a record for the fastest subsonic transatlantic commercial plane flying – 5 hours and 13 minutes, thanks to a 202 mph tailwind. "

For reference, the speed of the sound is 760 mph; but the plane does not break the sound barrier. That is because part of the speed of the plane is attributed to the swift transfer of 200 mph + that surrounds the plane. So relative to the air around it, the speed of the plane is very far.

Jet rivers like a Monday can have a great impact on flights.

"A 100 mph increase in the top-level jet stream can add or remove about an hour from five to six hours flight," according to a spokeswoman from FlightAware, a global aviation software and data services company based in Houston.

While you are surprised at an early arrival in the east, it is likely to face westbound delays battling the strong headwind. While the magnitude of this air affects the air travel, FlightAware says that upper air levels change is counted.

"Estimated jet stream winds are considered for flight planning, and even before scheduling you will find that the more stringent blocks In the interactive maps above, created by Cameron Beccario, the intensity of jet stream can be seen (updated every three hours).


What causes the record jet stream?

] The jet stream record is not only confined to the New York City area, it is a common theme throughout the Northeast due to a unique outcome of the events.

Everything started in the Pacific Ocean: Last week [19459009IntroductionoftheUnitedStatesofAmericaNewNoño in the tropical Pacific Ocean El Niño is a warming of the equatorial sea surface temperatures which may have effects thousands of miles away. This is partly responsible for the recent bad weather in California last week o.

"The last two weeks the environment has become more in El Niño state because it helps with another natural phenomenon in the climate known as MJO," Dr. said. Adam Sobel, professor of applied physics at the Lamont-Doherty Earth Observatory of Columbia University. "MJO is associated with clusters of storms and wind blows."

As a result of happy energy, two cyclones are formed in the central Pacific and all these activities boost a powerful sub-tropical jet stream across Mexico and the south of the US

At the same time, a strong polar jet stream in Alaska is split into two branches on the Pacific Coast. One goes east through the Great Lakes, while the other heads south to California and then move east to the Ohio Valley.

The result was all three medium jets – with an assist from the polar vortex – now incorporating the Northeast. It boosts a strong jet stream, in a record breaking one.

The flow of events is more easily understood by looking at the following illustration :

The wet and energetic jet stream will stay in place by the weekend. As a result, dangerous flooding is possible throughout the Mississippi and Tennessee Valley with a wide 5-10 inches of rainfall possible in some areas.
