Since 2009 the Hong Kong Observatory has divided typhoons into three different classifications: typhoon, severe typhoon and super typhoon. [20] A typhoon has wind speed of 64–79 knots (73–91 mph; 118–149 km/h), a severe typhoon has winds of at least 80 knots (92 mph; 150 km/h), and a super typhoon has winds of at least 100 knots (120 mph ...

A tropical cyclone is the generic term for a warm-cored, non-frontal synoptic-scale low-pressure system over tropical or subtropical waters around the world. [4] [5] The systems generally have a well-defined center which is surrounded by deep atmospheric convection and a closed wind circulation at the surface. [4]
Tropical cyclones regularly affect the coastlines of most of Earth's major bodies of water along the Atlantic, Pacific, and Indian oceans. Also known as hurricanes, typhoons, or other names, tropical cyclones have caused significant destruction and loss of human life, resulting in about 2 million deaths since the 19th century.
Between 1979 and 2016, typhoons increased in duration by two to nine hours and penetrated 30 to 190 kilometers farther inland, the researchers found. The study was published in the journal ...
This often causes widespread damage and flooding. Hurricanes can be categorised by their peak sustained wind speed. Major hurricanes are rated category three and above, meaning they reach at least ...
There are a number of structural characteristics common to all cyclones. A cyclone is a low-pressure area . [ 18 ] A cyclone's center (often known in a mature tropical cyclone as the eye ), is the area of lowest atmospheric pressure in the region. [ 18 ]
The Philippines faced six back to back typhoons in just 23 days last month, an unprecedented onslaught of storms that scientists say were fueled by unusually hot oceans and higher air humidity ...
