Question

Give a geographical reason for the following:

Heating of Pacific waters affects Indian Monsoon.

Give Reasons

Solution

Heating of Pacific waters (El Niño) warms the equatorial Pacific, alters the Walker circulation and shifts convection eastward, weakening the pressure gradient over the Indian Ocean. This disrupts monsoon wind flow and reduces moisture advection into India, causing a delayed/weakened southwest monsoon and less rainfall.
