Ans:  Cyclone is primarily formed in the area where the atmospheric pressure is low. The Ocean water near the equator creates a favorable atmosphere for the formation of the cyclone. The moist air over the ocean rises in an upward direction and creates a low-pressure zone over the air. To compensate for the air pressure, water from the low high-pressure area to the low-pressure zone moves faster. The moist air over the atmosphere also cools the upper air layer and helps in the formation of clouds. The whole system enlarges gradually with time, and finally, in the center, an eye is created. An eye is nothing but A concentrated low-pressure center to which surrounding air from the high-pressure zone flows, and the entire system creates a cyclone. A thunderstorm also has the same phenomenon as that of a cyclone. Due to uneven warming of the atmospheric air, water droplets rise vertically. Because of this phenomenon, condensation of air takes place and releases latent heat. The droplets at certain heights get cooled and fall again on the earth with hail and lightning.
