Tropical cyclones are rotating storms with strong winds and heavy precipitation. Depending on the location, they are called hurricane, typhoon, or cyclone. Tropical cyclones damage crops and built environment, drive human displacement, and cause mortality. This indicator counts how many tropical cyclones occurred in a grid cell over the past 12 months.
