Abstract The article selects daily high temperature data from Taizhou National Meteorological Station from 1961 to 2022 and NCEP/NCAR atmospheric circulation data to analyze and summarize the characteristics of high temperature changes in Taizhou City over the past 60 years,as well as the circulation characteristics and causes of abnormal high temperatures in 2022.The results show that the number of high-temperature days and extreme maximum temperatures at Taizhou station have shown an upward trend since the 1980s,and the upward trend has been significant since 2010.The high temperature events in 2013,2017,and 2022 showed significant extremism.In the summer of 2022,the highest temperatures at all stations in Taizhou reached historical extremes,showing overall characteristics of high intensity,strong extremism,and long duration.Under the control of the strong development of the continental high pressure ridge in June 2022 and the abnormally strong westward subtropical high pressure in the western Pacific from July to August,sinking airflow prevails in the Taizhou area,and the 850 hPa temperature is significantly higher,which is the main reason for this high temperature event.

Key words： high temperature atmospheric circulation Western Pacific subtropical high
