In which type of front is the flow of air on both sides of the front almost parallel to the line of the front

A. Warm

B. Occluded

C. Cold

D. Stationary

The answer is; D

This type of front behaves like a warm front only that it is quiescent because the front barely shifts its position. The weather may also be similar to that of a warm front. The two abutting air masses run almost parallel to the front because none is stronger than the other to cause displacement.

D. Stationary
