Question

benefits of westerly depressions in punjab

Answer 1

Western disturbances start declining in numbers after winter. During the summer months of April and May, they move across north India. The southwest monsoon current generally progresses from east to west in the northern Himalayan region, unlike western disturbances which follow a west to east trend in north India with consequent rise in pressure carrying cold pool of air. This helps in the activation of monsoon in certain parts of northwest India.

The interaction of the monsoon trough with western disturbances may occasionally cause dense clouding and heavy precipitation
