Final answer:
SW Monsoon winds crossing the equator into the N Hemisphere undergo a change in direction due to the Coriolis force and result in clockwise rotation. In the N Hemisphere, these winds bring moisture and rainfall during the summer monsoon season.
Step-by-step explanation:
When the Southwest (SW) Monsoon winds cross the equator into the Northern Hemisphere, they undergo a change in direction due to the Coriolis force. In the Northern Hemisphere, these winds are deflected to the right, resulting in a clockwise rotation. This clockwise rotation in the Northern Hemisphere is opposite to the counterclockwise rotation in the Southern Hemisphere.
As a result, the SW Monsoon winds that cross the equator into the Northern Hemisphere bring moisture and rainfall to regions in the Northern Hemisphere, such as India, during the summer monsoon season.
This exchange of winds and moisture plays a significant role in the climate patterns and rainfall distribution of the affected regions.
