Extra-tropical (Mid-Latitude) Cyclones . 11 ... • Focus on the tracking step: Why clustering ? A tropical cyclone is one of the Earth's strongest forces, a combination of strong, howling winds and heavy precipitation. When this happens we see the cyclone "re-curve" and begin moving toward the east in the same direction as non-tropical weather systems do in those locations. As the air rises it cools then condenses, forming clouds. Because this air moves up and away from the surface, there is less air left near the surface. The names are chosen based on regional level rules and are meant to be recognizable to people in that area. Tropical depressions, tropical storms, and hurricanes are all example of tropical cyclones. Haiyan may have had the highest wind speeds of any tropical cyclone on record, but we will never know for sure because we do a poor job estimating the intensity of storms that are not surveyed by aircraft. The atmosphere must cool fast enough with height, such that it is potentially unstable to moist convection. Tropical cyclone warning services. Analysis 1.
