By analyzing the speed of tropical cyclones and daily precipitation in China between 1961 and 2017 and examining simulations of a set of global climate models, researchers identified a 10-11% slowdown of tropical cyclones over the coast of China and a significant increase in extreme rainfall induced by tropical cyclones; the results suggest that low cyclone speed increases cyclone passage time and total amount of local rainfall, thereby increasing flood risks.
