  2. Wind shear - Wikipedia

    en.wikipedia.org/wiki/Wind_shear

    An increasing nocturnal, or overnight, low-level jet can increase the severe weather potential by increasing the vertical wind shear through the troposphere. Thunderstorms in an atmosphere with virtually no vertical wind shear weaken as soon as they send out an outflow boundary in all directions, which then quickly cuts off its inflow of ...

  3. Jet stream - Wikipedia

    en.wikipedia.org/wiki/Jet_stream

    The mountain barrier increases the strength of the low level wind by 45 percent. [113] In the North American Great Plains a southerly low-level jet helps fuel overnight thunderstorm activity during the warm season, normally in the form of mesoscale convective systems which form during the overnight hours.

    [1]: 2 At 09:30:37 (16:30:37 UTC), the aircraft received Automatic terminal information service "Lima", that was about 40 minutes old, stating "Wind three one zero at one three gust three five; low level wind shear advisories are in effect, local aviation wind warning in effect calling for winds out of the northwest gust to 40 knots (74 km/h ...

  5. Low-level windshear alert system - Wikipedia

    en.wikipedia.org/wiki/Low-level_windshear_alert...

    Pilots may decide whether to land (or conduct a missed approach) after wind shear alerts are issued. LLWAS wind shear alerts are defined as wind speed gain or loss of between 20 and 30 knots aligned with the active runway direction. "Low level" refers to altitudes of 2,000 ft (610 m) or less above ground level (AGL).

  6. Clear-air turbulence - Wikipedia

    en.wikipedia.org/wiki/Clear-air_turbulence

    Wind shear, a difference in relative speed between two adjacent air masses, can produce vortices, and when of sufficient degree, the air will tend to move chaotically. [10] A strong anticyclone vortex can also lead to CAT. [11] Rossby waves caused by this jet stream shear and the Coriolis force cause it to meander. [clarification needed]

    A fiery January crash of a B-1 bomber in South Dakota was caused by multiple crew failures, terrible winter weather and a last-minute brush with wind shear that resulted in all four members ...

    The accident was investigated by the National Transportation Safety Board (NTSB), which revealed that minutes before Flight 66's crash, a Flying Tiger Line Douglas DC-8 cargo jet landing on Runway 22L reported tremendous wind shear on the ground. The pilot warned the tower of the wind-shear conditions, but other aircraft continued to land.

  9. Astronomers detect ferocious jet-stream winds on alien planet

    The supersonic jet-stream winds circling WASP-127b at its equator are the fastest of their kind on any known planet. "There is an extremely fast circumplanetary jet wind found on the planet.
