Three different tropical cyclones active over the Western Pacific Ocean on August 7, 2006 (Maria, Bopha, and Saomai). The cyclones on the lower and upper right are typhoons. A typhoon is a tropical cyclone that develops between 180° and 100°E in the Northern Hemisphere and which produces sustained hurricane-force winds of at least 119 km/h ...
Tropical cyclones are ranked on one of five tropical cyclone intensity scales, according to their maximum sustained winds and which tropical cyclone basins they are located in. Only a few classifications are used officially by the meteorological agencies monitoring the tropical cyclones, but other scales also exist, such as accumulated cyclone ...
t. e. A tropical cyclone is a rapidly rotating storm system with a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is called a hurricane (/ ˈhʌrɪkən, - keɪn /), typhoon ...
The western 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).

The Philippines is a typhoon -prone country, with approximately 20 typhoons entering its area of responsibility per year. Locally known generally as bagyo ([bɐgˈjoʔ]), [ 3 ] typhoons regularly form in the Philippine Sea and less regularly, in the South China Sea, with the months of June to September being the most active, August being the ...
The Joint Typhoon Warning Center classifies typhoons of 150 mph (240 km/h) or greater (strong Category 4 and Category 5) as super typhoons. Most weather agencies use the definition for sustained winds recommended by the World Meteorological Organization (WMO), which specifies measuring winds at a height of 33 ft (10.1 m) for 10 minutes, and ...
The most intense storm by lowest pressure and peak 10-minute sustained winds was Typhoon Tip, which was also the most intense tropical cyclone ever recorded in terms of minimum central pressure. Storms with a minimum pressure of 899 hPa (26.55 inHg) or less are listed. Storm information was less reliably documented and recorded before 1950. [6]
t. e. Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including ...
