Is Climate Change Redefining the Acceleration Limit of Tropical Cyclones?
This study addresses whether recent trends in tropical cyclone (TC) intensification rates can be explained by the natural variability of the climate system. Two observational datasets are used to calculate 24-hour wind speed changes over the period 1982-2009 and determine whether the relative frequency of extreme intensification rates has increased. In general, TCs are found to accelerate more quickly but there are large variations depending on the basin and the dataset.
