What are monsoonal systems?

Monsoonal systems are like giant weather switches that flip on and off twice a year, changing what kind of weather you get where you live.

Imagine your room has a fan that blows air from the window to the center of the room, that’s like part of a monsoonal system. In some places, during certain times of the year, warm air rises from the land or ocean, and cooler air rushes in to replace it, just like when you open a window on a hot day, cool air comes rushing in.

During one season, the land heats up faster than the sea, causing the warm air above the land to rise. This pulls in cool, moist air from the ocean, which brings rain. That’s the rainy season!

Then, when the seasons change, the ocean becomes warmer, and the air above it rises, pulling cool air from the land toward the sea. This is usually a drier time of year.

Monsoonal systems are like having a big, friendly neighbor who brings you rain in one part of the year and lets you have sunny days in another, it all depends on where you live!
