In some inland areas that are less affected by tropical cyclones (such as Qinghai, etc.), there is no typhoon warning signal, but when it is hit by tropical cyclones, a strong wind warning signal will be ...
For the intensity scale, PAGASA lowered the threshold wind speed for classifying super typhoons from 220 km/h to 185 km/h and defined a super typhoon as an extreme tropical cyclone with 10-minute maximum sustained winds reaching 185 km/h or greater (the range of wind speed for typhoon category is consequently adjusted to 118–184 km/h).
A term used by the Japan Meteorological Agency to describe a typhoon with 10-minute windspeeds between 88–117 km/h (55–73 mph). Storm surge An abnormal rise in sea level accompanying a hurricane or other intense storm, and whose height is the difference between the observed level of the sea surface and the level that would have occurred in ...
Depending on its location and strength, a tropical cyclone is called a hurricane (/ ˈ h ʌr ɪ k ən,-k eɪ n /), typhoon (/ t aɪ ˈ f uː n /), tropical storm, cyclonic storm, tropical depression, or simply cyclone.

They form over low pressure systems. In the North Atlantic and the Eastern Pacific, the term "hurricane" is used, whereas "typhoon" is used in the Western Pacific near Asia. The more general term "cyclone" is used in the rest of the ocean basins, namely the South Pacific and Indian Ocean. [1] Tropical cyclones can be categorized by intensity.

The West Pacific is the most active and the north Indian the least active. An average of 86 tropical cyclones of tropical storm intensity form annually worldwide, with 47 reaching hurricane/typhoon strength, and 20 becoming intense tropical cyclones, super typhoons, or major hurricanes (at least of Category 3 intensity).
