Why and How are Cyclones made?

Answer 1

An atmospheric circulation system in which the sense of rotation of the wind about the local vertical is the same as that of the Earth's rotation. Thus, a cyclone rotates clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere. In meteorology the term cyclone is reserved for circulation systems with horizontal dimensions of hundreds (tropical cyclones) or thousands (extratropical cyclones) of kilometers. For such systems the Coriolis force due to the Earth's rotation, which is directed to the right of the flow in the Northern Hemisphere, and the pressure gradient force, which is directed toward low pressure, are in opposite directions. Thus, there must be a pressure minimum at the center of the cyclone, and cyclones are sometimes simply called lows. See also Air pressure.

Extratropical cyclones are the common weather disturbances which travel around the world from west to east in mid-latitudes. They are generally associated with fronts, which are zones of rapid transition in temperature. Extratropical cyclones arise due to the hydrodynamic instability of the upper-level jet stream flow. See also Front; Jet stream.

Tropical cyclones, by contrast, derive their energy from the release of latent heat of condensation in precipitating cumulus clouds. Over the tropical oceans, where moisture is plentiful, tropical cyclones can develop into intense vortical storms (hurricanes and typhoons), which can have wind speeds in excess of 200 mi/h (100 m · s−1).

Answer 2

A cyclone is formed over tropical seas. Winds from opposite directions meet. This air is heated by the warm seas and so evaporates moisture from the ocean. This warm air rises up rapidly, cools and condenses to form clouds and produces an area of very low pressure. When moisture and air mix, it makes a collection of thunderstorms from which a cyclone can develop. Water needs to be at least 26 degrees warm so a tropical cyclone can develop.

More air is sucked in to take its place, and it too is heated and rises rapidly. This sucking in and risins movement of the air produces spiralling clouds. Eventually, an enormous storm system is built up, which can spread over two hundred kilometres. Heavy rain falls from the clouds. There is much thunder and lightning and the fast winds whip up the waves of the ocean.

In the middle of this system, air moves down. This produces a patch of drier, calm weather with few clouds. It is called the 'eye' of the storm and can last for an hour before the fierce winds and torrential rainstorms sweep in again. When the cyclone hits land, it soon weakens as there is no warm, moist air to 'feed' the storm.

Answer 3

Cyclones are formed when warm, moist air over the ocean rises and creates a low-pressure area. As this air cools and condenses, it releases energy that fuels the storm. The rotation of the Earth helps to spin the storm into a cyclonic shape as it gains strength and moves across the ocean.

Answer 4

it is made of particles of ice and minerals

water

As a typhoon is a pacific cyclonic tropical storm it is made up of a great wind
