Why is Chicago so windy?


assistant
A lot of Chicago's wind comes from the air above nearby Lake Michigan. The sun heats up the land faster than it heats up the water in the lake. When the air in the city rises, the cooler air over the lake moves toward the land. The air movement makes a lot of wind.
