How does the Atlantic cold blob affect the Indian summer monsoon?

The Atlantic cold blob makes the Indian summer monsoon weaker by sending cooler water across the ocean, which changes how wind moves.

Imagine you're playing with a toy boat in a bathtub. If the water is warm, it pushes the boat forward easily, like a gentle breeze helping your boat sail. But if the water gets cold, it’s like the bath becomes still or even starts to pull the boat back, making it harder for the boat to move.

The Atlantic cold blob is like a big patch of cooler water in the middle of the Atlantic Ocean. It acts like a "slow down" button for the winds that travel across the ocean and reach India. These winds are important because they bring rain during the summer monsoon season.

When the Atlantic cold blob is strong, it changes how wind moves from one part of the ocean to another. This change affects the strength and timing of the Indian summer monsoon, making it less intense or even delayed, like a rain shower that comes later than expected or brings less water than usual.
