A tropical cyclone is a rapidly rotating storm that begins over tropical oceans, and they can vary in speed, size, and intensity. Tropical cyclones are the second-most dangerous natural hazards, after earthquakes.
A tropical cyclone is a rapidly rotating storm originating over tropical oceans from where it draws the energy to develop. It has a low-pressure centre and clouds spiralling towards the eyewall surrounding the "eye", the central part of the system where the weather is normally calm and free of clouds. Its diameter is typically around 200 to 500 ...
Oct 1, 2019 · Tropical Cyclones. Tropical cyclones, also known as typhoons or hurricanes, are among the most destructive weather phenomena. They are intense circular storms that originate over warm tropical oceans, and have maximum sustained wind speeds exceeding 119 kilometres per hour and heavy rains. However, the greatest damage to life and property is ...
The naming procedures can vary, with some regions using alphabetical order and others using the alphabetical order of country names. It is important to note that tropical cyclones are not named after individuals. When selecting a new name, consideration is given to certain factors: Uniqueness – same names cannot be used in other regions.
The Operational Tropical Cyclone Plans/Manual drawn up by TC Regional Bodies are important accomplishments in this field. Hydrology. Activities under this field are based on the WMO Operational Hydrology Programme (OHP) and are concerned with the provision of the required basic hydrological data and the application of the appropriate techniques ...
This website of the World Meteorological Organization (WMO) is aimed to serve as a platform for the information sources for tropical cyclone forecasters to obtain data and tools which are useful for monitoring and forecasting of tropical cyclones.

In 1979, men's names were introduced and they alternate with the women's names.
The advisories and warnings are issued by the respective RSMCs, TCWCs and the NMHSs in the Typhoon Committee region. Information presented in tropical cyclone advisories and warnings issued by the various centres may differ owing to differences in the availability of observational data, operational cut-off times, numerical weather prediction ...
