AbstractThe characteristics of typhoon activities over western North Pacific and the South China Sea in 2024,as wellas the tracks,intensities,windand rainfallof the typhoons that had great influence on China were summarizedand analyzed statisticall.The data used included the real-time operation data of the Central Meteorological Observatory,the best track data of China Meteorological Administration,Fengyun satelite data and conventional observing data.The analysis results are as follows.(1)A total of 26 typhoons were formed over western North Pacific and the South China Sea in 2O24,which was basically the same as that of the climate average.The formation regions were further north and west,the generation time was more concentrated,and the typhoons in autumn were more active. (2) A total of 8 typhoons landed in China's coastal areas,which was more than the climate average.The landfalling sites were concentrated in the coastal areas of East China and South China,and the number of typhoons landing on Taiwan and Shanghai was obviously higher than that in normal years.The average intensity of initial landings was stronger,and the total landing times were more than the average.Typhoon Yagi has been the strongest typhoon landing on China in autumn since meteorological records began.(3) There were 468 rivers in 25 provinces that had exceeded the warning level. Typhoon Gaemi caused a large-range and long-term heavy rainfall in Northeast China,North China,regions south of the Yangtze River and Southwest China.
