More Than Just Rain

A monsoon is not a storm. It is a seasonal reversal of wind, a yearly flip between a wet half of the year and a dry one. When summer bakes the Asian landmass, hot air rises and pulls moist ocean air inland for months. The payoff is staggering: India gets about 75% of its yearly rainfall in the four months from June to September.

More than a billion people lean on this rain for the food they grow and the water they drink. That is why the Indian monsoon is often called the most economically important weather pattern on the planet. A single season decides whether crops thrive, prices stay steady, and reservoirs refill, or whether all three go wrong at once.
