Geostrophic deflection force
• In meteorology, a tropical cyclone is a storm system fueled by the heat released when moist air rises and condenses. The name underscores their origin in the tropics and their cyclonic nature, which is that its circulation is counterclockwise in the northern hemisphere and clockwise in the southern hemisphere. They are distinguished from other cyclonic windstorms such as nor'easters, European windstorms, and polar lows by the heat mechanism that fuels them, which makes them "warm core" storm systems.
