The northern polar jet stream is the most important one for aviation and weather forecasting, as it is much stronger and at a much lower altitude than the subtropical jet streams and also covers many countries in the northern hemisphere, [38] while the southern polar jet stream mostly circles Antarctica and sometimes the southern tip of South ...
The Gulfstream G650 is a large business jet produced by Gulfstream Aerospace. [4] The model is designated Gulfstream GVI in its type certificate. [5] The aircraft can be configured to carry from 11 to 18 passengers over a range of 7,000 nautical miles [nmi] (13,000 km; 8,100 mi) at a top speed of Mach 0.925 (530.6 kn; 982.7 km/h; 610.6 mph).
The jet stream, a high-level wind band, can stretch cirrus clouds long enough to cross continents. [24] Jet streaks, bands of faster-moving air in the jet stream, can create arcs of cirrus cloud hundreds of kilometers long. [25]
The plane was in the air less than 30 minutes before reaching speeds of over 800 mph over the Atlantic. Pilots have been exploiting the augmented jet stream to coast across the Atlantic Ocean at ...
The Atlantic jet stream is a fast and narrow current of air flowing from west to east and encircling the globe and is widely used by airplanes traveling east from North America to cut down on ...
In recent weeks, the jet stream has appeared unusual and disjointed, scientists say. Some researchers think climate change is disrupting its flow and causing it to bake regions in heat longer.
Scottish Aviation had taken over production of the original Jetstream design from Handley Page, and when it was nationalised along with other British companies into British Aerospace (later BAE Systems) in 1978, British Aerospace decided the design was worth further development, and started work on a "Mark 3" Jetstream.
For example, near the jet stream, winds increase when approaching its most intense region and decreases when it moves away. Thus, there are areas where the air accumulates and must come down, while in other areas there is a loss and an updraft from lower layers.
