Flows Cross Over a Mountain
Westerly over mountain
Easterly over mountain
Steady westerly flow
over a large-scale ridge will result in a cyclonic flow pattern immediately
to
the east of the barrier
(the lee side trough) followed by an alternating series of ridges and
troughs downstream.
In the case of an easterly wind, the disturbance in the streamlines damps out away from the barrier.
