Document Summary
Most obvious economic impact: rebuilding of damaged infrastructure. Other costs that are less often considered: cost of evacuation, impact on energy production, cost of severe coastal erosion. Develops over the tropical or subtropical waters. Has an organized circulation with winds of at least 120 km/h. Another mechanism of warming in the tropical cyclone"s center is subsidence. As the air in the eye of the cyclone sinks, it warms due to compression. Tropical cyclones (tcs) always originate over the tropical oceans (in maritime tropical air masses) Hurricanes are used to describe tcs that occur over the atlantic and the eastern pacific. Typhoons are the same as hurricanes, but occurring in the western pacific ocean. Cyclones occur over the indian ocean region. Tropical cyclones do not form near the equator. Storms tend to curve to the east and north as they interact with the westerlies.
