Classifying And Naming Hurricanes
Classifying and naming hurricanes is based on intensity of the storm. On this page we will take a look at how scientists classify and name hurricanes based on a series of factors. Read on.
Classification of hurricanes, based on intensity is done into three main groups.
1. Tropical depressions
2. Tropical storms
3. Third group of more intense storms, whose name depends on the region
If a tropical storm in the Northwestern Pacific area touches the strength of winds on the Beaufort scale, it is known as typhoon. But if a tropical storm of the same intensity, crosses the Northeast Pacific Basin or in the Atlantic it is called a hurricane. But neither the typhoon or hurricane names are used in either the Southern Hemisphere or the Indian Ocean. Here they are simply referred to simply as "cyclones". Additionally, each basin uses separate system of classifying and naming hurricanes. For instance, hurricanes from the Central North Pacific crossing the International Date Line into the Northwest Pacific, in the Pacific Ocean, become typhoons. Read on to know more on classifying hurricanes.
A tropical depression is a structured system of clouds and thunderstorms with a distinct, closed surface circulation. The maximum persistent winds are of less than 17 meters per second. There is no eye and they also do not typically have the spiral shape of more powerful storms. As it is already a low-pressure system, therefore the name "depression
A well defined surface circulation and highest sustained winds between 17 meters per second and 32 meters per second form the tropical storms. Although an eye is not usually present, it has the distinctive cyclonic shape.
Hurricane or typhoon
A hurricane or typhoon is a system with continued winds of at least 33 meters per second or 74 miles per hour. Developing an eye, at the center of circulation, this is an area of relative calm and lowest atmospheric pressure. The satellite images show this eye as a small, circular, cloud-free spot. Surrounding the eye is the eyewall, an area about 16 kilometers to 80 kilometers in width comprising of strongest thunderstorms and winds circulating around the storm's center
