Solution(By Examveda Team)

Depression in the southern hemisphere is a mass of air whose isobars form an oval or circular shape. In the southern hemisphere, the circular movement of winds is in a clockwise direction. Depressions are rarely stationary and tend to follow definite tracks. They are most influential over the ocean spreads and they weaken over land areas.
