The wind shear associated with several major airline crashes is believed to have been caused by
A) microbursts.
B) dry lines.
C) the jet stream.
D) mesocyclones.

Question

Quizplus · Accepted Answer

Wind shear is commonly associated with microbursts, which are small-scale downdrafts that can create hazardous conditions for aircraft during takeoff and landing. Dry lines are boundary layers between different air masses, and while they can produce thunderstorms and other weather phenomena, they are not typically associated with the kind of sudden, low-level winds that cause wind shear. The jet stream is a high-altitude air current that can influence weather patterns, but it does not usually produce the kind of localized, low-level turbulence that causes wind shear. Mesocyclones are rotating thunderstorms that can produce tornadoes, but wind shear is not necessarily a defining characteristic of them.
