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.

The option a and c are correct as they both refer to the air mass wind shear as it occurs at night under fair weather conditions and also in the presence of strong fronts. Similarly, if the radiational cooling is strong enough then it can result in ground based inversion. The option b and d are incorrect as it develops when the grounds become cooler not warmer than the overlying air mass. As the statement in b is not correct so the option d is also incorrect.
