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]
Typhoon Champi (2015) The Northern Mariana Islands are an archipelago north of Guam which gets impacted by typhoons in the western Pacific from time to time. Typhoon Champi dropped 26.25 inches (667 mm) on Tinian in 2015, [93] making it the wettest known tropical cyclone for the island chain.
Typhoon Haiyan (Yolanda) on November 7, 2013, one of the strongest Pacific typhoons ever recorded.. Since 1947, the Joint Typhoon Warning Center (JTWC) has classified all typhoons in the Northwestern Pacific Ocean with wind speeds of at least 130 knots (67 m/s; 150 mph; 240 km/h)—the equivalent of a strong Category 4 on the Saffir–Simpson scale, as super typhoons.

A very strong typhoon has wind speeds between 85–104 kn (44–54 m/s; 98–120 mph; 157–193 km/h), while a violent typhoon has wind speeds of 105 kn (54 m/s; 121 mph; 194 km/h) or greater. [8] The HKO, SMG and the CMA also divide the typhoon category into three categories, with both assigning a maximum wind speed of 80 kn (41 m/s; 92 mph ...
In the peak of Atlantic hurricane season, words matter. And using the right ones at the right time can be the difference between alerting of a far-out rotating storm system to a nearer full-blown ...
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).
