The relative sizes of Typhoon Tip, Cyclone Tracy, and the United States. Larger tropical cyclones have larger rain shields, which can lead to higher rainfall amounts farther from the cyclone's center. [6] This is generally due to the longer time frame rainfall falls at any one spot in a larger system, when compared to a smaller system.
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 ...
For example, it is estimated that flood heights from Hurricane Katrina in 2005 - one of America's deadliest storms - were 15-60% higher than they would have been in the climate conditions of 1900.
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]

All tropical cyclone tracks between the years 1985 and 2005. The United States tropical cyclone rainfall climatology concerns the amount of precipitation, primarily in the form of rain, which occurs during tropical cyclones and their extratropical cyclone remnants across the United States.
Of the 197 hurricanes classified as Category 5 from 1980 to 2021, five fit the description of a hypothetical Category 6 hurricane: Typhoon Haiyan in 2013, Hurricane Patricia in 2015, Typhoon ...
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.
