Tropical cyclone

A hurricane or typhoon or a cyclone is a large cyclonic weather system with continuing winds of at least 33 m/s (64 kt, 74 mph, or 118 km/h) A tropical cyclone with this wind speed usually develops an eye, which is an area of calm conditions at the center of its circulation The eye is often seen from space as a small, round, cloud-free spot...

Mesocyclone

A mesocyclone is a vortex of air, about 2 to 10 km in diameter (the mesoscale of meteorology), inside a convective storm That is, it is air that rises and rotates around a vertical axis, usually in the same direction as low pressure systems in a given hemisphere...

Tropical cyclone

A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain or squallsDepending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (/ ˈ h ʌr ɪ k ən,-k eɪ n /), typhoon (/ t aɪ ˈ ....

Typhoon Meranti

Typhoon Meranti, known in the Philippines as Typhoon Ferdie, was one of the most intense tropical cyclones on record Impacting the Batanes in the Philippines, Taiwan, as well as Fujian Province in September 2016, Meranti formed as a tropical depression on September 8 near the island of GuamTracking to the west northwest, Meranti gradually intensified until September 11, at which point ,...

Tropical cyclone rainfall climatology

A tropical cyclone rainfall climatology is developed to determine rainfall characteristics of past tropical cyclon A tropical cyclone rainfall climatology can be used to help forecast current or upcoming tropical cyclone impacts The degree of a tropical cyclone rainfall impact depends upon speed of movement, storm size, and degree of vertical wind shear...

Principles:Dense Medium Cyclone

The medium density at which the separation between more dense and less dense material occurs is called the cut point density Invariably, there often is a percentage of the feed coal distribution which gets trapped in an envelope of zero velocity inside the cyclone where ,...

Polar cyclone

Polar cyclones (also known as Arctic Cyclones) are large areas of low pressureThey should not be confused with polar lows since people happen to use the same term for polar cyclon Polar cyclones are usually 1,000 to 2,000 kilometers wide in which the air is moving in a spiral counterclockwise fashion in the northern hemisphereThe reason for the rotation is the same as tropical cyclones ....

Annular tropical cyclone

An annular tropical cyclone is a tropical cyclone that features a normal to large, symmetric eye surrounded by a thick and uniform ring of intense convection, often having a relative lack of discrete rainbands, and bearing a symmetric appearance in general As a result, the appearance of an annular tropical cyclone can be referred to as akin to a tire or doughnut...

Dvorak technique

The Dvorak technique (developed between 1969 and 1984 by Vernon Dvorak) is a widely used system to estimate tropical cyclone intensity (which includes tropical depression, tropical storm, and hurricane/typhoon/intense tropical cyclone intensities) based solely on visible and infrared satellite imagWithin the Dvorak satellite strength estimate for tropical cyclones, there are several visual ....

Cyclogenesis

Cyclogenesis is the development or strengthening of cyclonic circulation in the atmosphere (a low-pressure area) Cyclogenesis is an umbrella term for at least three different processes, all of which result in the development of some sort of cyclone, and at any size from the microscale to the synoptic scale Tropical cyclones form due to latent heat driven by significant thunderstorm activity ....

Cyclone Fani

Development proceeded more slowly over the following days, with little improvement evident in the system's satellite presentation On 2 May, however, the central dense overcast became more symmetrical and the eye more distinct, and Fani was upgraded to a Category 4-equivalent cyclone by the JTWC at 06:00 UTC...
