Abstract

[1] The trends in tropical cyclone (TC) induced wind and precipitation are estimated by applying a quantile regression to station data collected from mainland China. Results indicate that stations located close to the southeast coast show significant decreasing trends in annual windy days, maximum sustained wind and wind gusts, while positive trends in precipitation per TC and maximum 1-hr precipitation dominate over the south of the Yangtze River. The TC frequency is generally decreased over China, especially over south China. The location of significant trends in precipitation seems to be related to the mountains and coastline in southeast China. The influence of local conditions, such as topography and urbanization, on circulation may contribute to the spatial pattern of trends in influence of TC activity. The different behaviors of trends in wind and precipitation also necessitate a more thorough metrics for assessing the impacts of TCs.
