Tropical depressions, storms, typhoons, and super typhoons are categories of tropical cyclones defined by wind speed. Tropical depressions have winds between 20-34 knots, tropical storms have winds between 34-64 knots, typhoons develop in the northwest Pacific with winds over 64 knots, and super typhoons are very strong typhoons with intense winds. The document then defines key parts of typhoons including the eye at the center, the eyewall just outside with tall clouds and high winds, and rainbands outside the eyewall.
