2022年夏季长江中下游地区太阳辐射异常及对极端高温的影响研究
Study on Abnormal Solar Radiation and Its Impact on Temperatures in the Middle and Lower Reaches of the Yangtze River in the Summer of 2022
摘要
Abstract
Based on the monthly Surface Solar Radiation(SSR),Maximum Temperature(Tmax),Average Temperature(Tave),Minimum Temperature(Tmin),and Daily Temperature Range(DTR)data from 1993 to 2022,the anomalous characteristics of SSR,temperature,and DTR in the middle and lower reaches of the Yangtze River in summer of 2022 were analyzed,focusing on the impact of SSR anomalies on temperature.Results show that:(1)on the climate average,the middle and lower reaches of the Yangtze River are in the national SSR low value area in summer,and one of the regions with the most obvious interannual variability.The SSR in this region in 2022 is the highest value in the past 30 a,reaching 1 860.35 MJ·m-2on average.(2)The temperature in most regions of China is higher than normal in summer 2022,with Tmax in the middle and lower reaches of the Yangtze River being the center of the anomaly.Most areas are more than 2℃ higher than normal,and DTR reaches the highest value in 2022 in the middle of 1993-2022 at 8.8℃.(3)Tmax in most areas of the middle and lower reaches of Yangtze River is anomalously higher than normal in summer 2022 due to SSR anomaly,and some stations are more than 2℃higher.关键词
