Changes of Tropical Cyclone Size in three Oceanic Basins of the Northern Hemisphere since 2001
In this study the latest changes of tropical cyclone size are analyzed based on linear and quadratic curve fittings of the National Hurricane Center (NHC)/Joint Typhoon Warning Center (JTWC) best track data for the radius of maximum wind (RMW), the average radius of 34-kt wind (AR34), and the storm...

In this study the latest changes of tropical cyclone size are analyzed based on linear and quadratic curve fittings of the National Hurricane Center (NHC)/Joint Typhoon Warning Center (JTWC) best track data for the radius of maximum wind (RMW), the average radius of 34-kt wind (AR34), and the storm duration index “storm days” (SD) in three oceanic basins of the North Atlantic (NATL), the Western North Pacific (WPAC) and the Eastern North Pacific (EPAC). The computations are done separately for two categories of tropical cyclones: tropical storms (TS), and hurricanes in NATL and EPAC or typhoons in WPAC (HT). The results show that the RMW trends for TS are positive in all basins, and the RMW trends for HT are positive in the NATL basin, but negative in the WPAC and EPAC basins. The AR34 changes are more complex due to the fact that they reflect not only the strength of tropical cyclones, but also the environmental conditions.
