What is cyclone?

A cyclone is a low-pressure weather system consisting of rain, thunderstorms, and strong vortices originating in tropical oceans that transports heat generated in the equatorial region toward the polar regions. 

In this type of storm, the wind moves around at high speed, so it is named as cyclone. Cyclone rotation is counterclockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere. Although a disaster occurs when a cyclone hits the coast, it is a normal process of weather, which maintains the heat balance on Earth. On average, about 80 cyclones occur in the world every year. Most of it ends up in the ocean. 

But the few that do hit the coast often cause devastating damage. Cyclones are caused by changes in wind speed and direction with altitude and rapid cooling, resulting in the release of heat that can cause cyclones. Sea temperature For a cyclone to form, the sea water temperature must be at least 26-27 degrees Celsius and up to a certain depth (at least 50 meters). This is why we usually see cyclones forming in summer or late summer in the oceans near the Tropic of Cancer and Capricorn. 

Not anywhere else. Distance from the Equator In the equatorial region, warm and moist air rises as the surface heats up during summer. To fill this gap, cold air from the polar regions flows southward towards the equator in the Northern Hemisphere and northward in the Southern Hemisphere. But the Coriolis force caused by the Earth's rotation Due to coriolis force, this wind does not flow straight and bends to the right in the northern hemisphere and to the left in the southern hemisphere. Hence we see that cyclones formed in Northern Hemisphere rotate counterclockwise and in Southern Hemisphere clockwise. The effect of this force on the equator is zero. 

Therefore, even though the temperature in this region is favorable for cyclone formation, since the Coriolis force is minimal, no cyclones occur between 0° and 5° of the equator. Generally, cyclones form between 10 degrees and 30 degrees of the equator. Atmospheric moisture More moisture in the lower and middle layers of the atmosphere plays a role in the formation of cyclones. Cyclones cannot arise spontaneously in the prevailing turbulent conditions. If there is a pre-existing turbulent condition in the ocean, a cyclone usually develops around it. Besides,
