Explanation:
Clouds move in opposite directions between the wind ,usually change direction with increasing height above the ground.
For example:- low-level clouds behind a cold frontal passage move to an area from the North East, whereas the winds aloft along with mid- and high-level clouds behind the front as still from the South West.
In the Northern Hemisphere, when the wind change direction from the surface to aloft in a clockwise (counter-clockwise) direction it is called ‘veering’ (‘backing’).
The veering (backing) vertical wind profile generates upward (downward) vertical motion warm (cold) air convection and dynamic instability.
