Why Do Typhoons Happen?

The typhoon is the name given specifically to the tropical cyclone that occurs in the northwest area of the Pacific Ocean and the western direction of the International Date Line. The similar cyclone in other regions is called as hurricanes or tropical cyclones. The central part of the cyclone is called as the eye. The calm and good weather is maintained by the eye in its circular form. The tropical cyclone eye was estimated to be 30 miles away. The eye walls that are covering the eye will form intense convection clouds. The eye walls are comprised of heavy winds which will be very strong and are able to cause destruction.

The convective clouds which are visualized as spiral bands will appear spiraling in the eye walls. This region of spiraling clouds consists of intense or heavy winds and they are originated from the typhoon eye. Typhoons are found to be occurring when a weather wave that is rough enough with the help of the rotation of earth starts to rotate. This phenomenon is known as Coriolis Effect. The pressure system will be generated very effectively and will be increased when the wave spins into a complete circle. This circle will have high pressure in the periphery and low pressure at the center. The multidirectional winds that are attracting the wave might disturb the pressure circle from its creation.

If the pressure circle maintains the rotation speed and starts to spin at the rate of more than 65 knots or 74mph is known as the tropical cyclone. The intensity of the typhoon was not found to be the result of the circle size. For the initiation of tropical cyclones, it is necessary for the oceanic water temperature to be maintained at 80 degrees F at least. The heat in the circling system is created from the water vapor whirling round in the atmosphere. This water vapor spiraling further will result in forming convective clouds. The starting of typhoons was found to be associated with the temperature of the sea surface.
