What is a tropical cyclone?
tropical cyclone is a type of weather system that moves through warm oceans and often brings rain, wind and high surf to coastal communities. The size of the tropical cyclone may vary from 120 miles (193.1 km) to 1200 miles (1,931.2 km) on average. It is a low -pressure system, which means that when it travels the weather that accompanies it will be more than likely to be cloudy and rainy. In the northern hemisphere, it spins in the direction of clockwise. When it moves on warm ocean water, the cyclone collects energy and heat from the water below. The whole evaporation of moisture from the sea basically makes the cyclone more powerful and powered it like an engine. This energy, combined with a spiral wind near the ocean surface, helps cyclone growing stronger and continue on its path.Al in an hour (61 km / h). If wind speed increases and winds flow from 39 mph (62.7 km/h) to 73 mph (117.5 km/h), the cyclone is then referred to as tropical storm . There is an officially tropical cyclone when the system has sentencesRY at least 74 mph (119 km / h).
In the western Northern Pacific Ocean, the tropical cyclone is referred to as Typehoon . In the eastern North Pacific and northern Atlantic, the tropical cyclone of the same force is referred to as hurricane .
The center of the tropical cyclone is referred to as eye . The air in the center or eye of the cyclone is warmer than the surrounding air that is part of the cyclone. The eye wall is an area surrounding the eye and consists of thick clouds. This is the area where the most activity happens, and meteorologists pay great attention to this part of the cyclone when watching its movement.
tropical cyclones usually last for more than one week. Their strength decreases as they travel on cold water, as well as when they have to travel on the masses of land.
tropical cyclones are associated with strong precipitation and strong winds. The high level of precipitation that occurs, noAsso leads to the risk of floods. For those who live near coastal areas, especially with low -lying coastal areas, the high surf, which is created by the wind from cyclone, may be the main risk. This is referred to as Storm Surge and is one of the main causes of victims and damage by tropical cyclone.
