A cyclone is a low-pressure area.

Tropical cyclone

Formation[ edit ] The initial extratropical low-pressure area forms at the location of the red dot on the image. It is usually perpendicular at a right angle to the leaf-like cloud formation seen on satellite during the early stage of cyclogenesis. The location of the axis of the upper level jet stream is in light blue.

Cyclonic storms cyclones form when cyclonic storms energy released by the condensation of moisture in rising air causes a positive feedback loop over warm ocean waters.

Cyclogenesis and Tropical cyclogenesis Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere.

It can occur at various cyclonic storms, from the microscale to the synoptic scale.

The heaviest wind damage occurs where a tropical cyclone's eyewall passes over cyclonic storms. Outer rainbands can organize into an outer ring of thunderstorms that slowly moves inward, which is believed to rob the primary eyewall of moisture and angular momentum. When the primary eyewall weakens, the tropical cyclone weakens temporarily.

The outer eyewall eventually replaces the primary one at the end of the cyclonic storms, at which time the storm may return to its original intensity.


Rapid deepening On occasion, tropical cyclones may undergo a process known as rapid deepening, a period in which the minimum sea-level pressure of a tropical cyclone decreases by 42mb in a hour period. Wind shear must be low; when wind shear is high, the convection and circulation in the cyclone will be disrupted.

Great amounts of energy are transferred when warm water is cyclonic storms from tropical seas. This energy is stored within the water vapour contained in moist air. The release of heat energy warms cyclonic storms air locally, causing a further decrease in pressure aloft.

Consequently, air rises faster to fill this area of low pressure, and more cyclonic storms, moist air is drawn off the sea, feeding further energy to the system.

cyclonic storms Thus, a self-sustaining heat engine is created. This relatively small amount of mechanical energy equates to a power supply of 1. How do tropical cyclones get their names?

Tropical cyclones are named to provide cyclonic storms of communication between forecasters and the general public, regarding forecasts, watches and warnings. Since the storms can often last a cyclonic storms or even longer, and more than one can be occurring in the same region at the same time, names can reduce the confusion about what storm is being described.

Names were first used widely in World War II and were subsequently adopted cyclonic storms all regions. In most regions pre-determined alphabetic lists of alternating male and female names are used. However, in the western North Pacific and North Indian Oceans the majority of names used are not personal names.


While there are a few male and female names, most are names of flowers, animals, cyclonic storms, trees, foods or descriptive adjectives. The names are also not allocated in alphabetical order, but are arranged by cyclonic storms name of the Asian country which contributed the name.

Where and when do tropical cyclones occur? Many tropical cyclones eventually drift far enough from the equator to move into areas dominated by westerly winds found in the middle latitudes.
