Please I need clarify on this:

Radiation inversions are unlikely to form on cloundy or windy nights.

if there is strong winds, surface layer doesn't get a chance to become cold enough to form inversion.

Final cyber:

The onset of a light wind beneath a radiation inversion will cause the inversion to become:

a) weaker but more shallow
b) stronger but more shallow
c) weaker but deeper
d) stronger but deeper
if it is light wind then inversion will form i mean high chane of it to form and stronger so it is mean the best best answer will be "D" I chose but I'm confuse with the second parts of the answers.
The two words (shallow and deeper) what actually meant by using them on radiation inversions?

Thank you
