Airmass wind shear: a. occurs at night under fair weather conditions in the presence of strong fronts. b. develops when the ground becomes warmer than the overlying airmass as a result of radiational cooling. c. may result in a ground based, or surface inversion, if the radiational cooling is strong enough, d. all the above b and c

Air mass wind shear:

a. Occurs at night under fair weather conditions in the presence of strong fronts.

c. May result in a ground based, or surface inversion, if the radiational cooling is strong enough.

Explanation:

Wind shear:

Wind shear is very important for pilots as it tells about the change in the wind horizontal or vertical distances. It can create problem for the landing planes.
