The chemical processes that are related to the cyclone formation.
Answers
Explanation:
To form a cyclone, warm, moist air over the ocean rises upward from near the surface. As this air moves up and away from the ocean surface, it leaves is less air near the surface. So basically as the warm air rises, it causes an area of lower air pressure below.
Answer:
The ocean water must be at least 26°C.
The atmosphere must have a low air pressure
A thunderstorm needs to be produced
The condensation of the evaporated water leads to the formation of clouds. During this process, heat is emitted and a reaction between the moisture from the evaporation of water takes place. Thunderstorms are produced and subsequently, if low air pressure is in the atmosphere, clouds will begin to rotate due to the Earth spinning on its axis. This causes thunderstorms to spin in a circular motion and a cyclone is created.
Cyclones have two types of gale force winds at the eye and they are known as sustained winds and gusts. Sustained winds can have a speed of 63km/h or more and gusts surpass the speed of 90km/h. These winds have a life-span of at least six hours. The winds are capable of extending over hundreds of kilometres from the centre of the cyclone. A tropical cyclone will be classified as severe if the

The eye of a tropical cyclone is surrounded by a dense circular formation of cloud which is approximately 16km high. This ring of cloud is known as the eye wall which contains the strongest winds and produces the heaviest rainfall.
Tropical cyclones acquire energy through the temperatures of the sea-surface which means that they disappear when they encounter land or colder water. Tropical Cyclones can persist for an average of a week.
