Abstract:Based on meteorological data from five national meteorological observation stations in Heyuan City from 1971 to 2020,the article employs methods such as linear trend analysis and moving average method to focus on exploring the spatiotemporal evolution of high temperature and heatwaves in Heyuan City,and deeply analyzes the driving effects of meteorological factors on them.The results indicate that high temperature and heatwaves in Heyuan City exhibit a spatial distribution characteristic of being more frequent in the east and less in the west,with Longchuan County being most significantly affected by this high temperature.The temporal distribution is mainly concentrated in June to September,with interannual variations showing an upward trend,with an average increase of 4.6 days per decade in the number of high temperature days.The synergistic effects of the subtropical high pressure,sinking airflow around tropical cyclones,as well as meteorological factors such as precipitation,wind speed,and atmospheric pressure,jointly influence the formation and development of high temperature and heatwaves in Heyuan City.
