Abstract：The high-resolution COSMO model in climate mode(CCLM)was used to simulate the 3-hour wave characteristics in the Bohai Sea,the Yellow Sea and the East China Sea.The simulation results for the base period(from 1979 to 2005)were compared with the wave characteristics changes from 2021 to 2050 under the RCP2.6 scenario.The results showed that the average annual wave height increased from the northwest Bohai Sea to the middle and east Yellow Sea.The average annual wave height in-creased the most in the middle and east Yellow Sea,and decreased in the east China Sea.In terms of the average annual cycle,most of the sea areas in the East China Sea were in a decreasing trend,and the decrease in the central and eastern parts could reach more than 0.02 s,while most of the Bohai Sea and Yellow Sea were in an increasing trend.The results could provide better climate change prediction data for the east China seas,and provided scientific basis for assessing the impact of future climate change and putting forward adaptive measures.
