National Climate Center： The duration of high temperature in China this summer is longer than normal, but the high temperature condition is weaker than that in 2022.

　　China news agency, Beijing, May 16 (Reporter Chen Su) The reporter learned from the National Climate Center on the 16th that the duration and range of high temperature in China this summer are still more than normal.

　　Recently, the first round of high temperature weather in the north hit. As of 14: 00 on the 15th, the TOP10 national temperature charts were all above 36℃, Jingxing in Hebei ranked first with 38.1℃, and Zhaitang in Beijing also reached 36.6℃.

　　Last summer, extreme high temperature and drought occurred in many places in China. Monitoring shows that in mid-April this year, the temperature in most parts of China was higher than that in the same period in history. In view of the weather situation this summer, Gao Hui, chief forecaster of the National Climate Center, said that the temperature in most parts of China this summer is close to the same period of the year, but the high temperature is weaker than that in 2022, and meteorological droughts may still occur frequently.

　　Gao Hui said that this summer, except for the central and northern parts of Heilongjiang, the temperature is expected to be slightly lower than normal, and the temperature in most parts of the country is close to normal to high, with the temperature in southern Henan, western Anhui, northwestern Jiangxi, northern Hunan, Hubei, most of Chongqing, eastern Sichuan, southwestern Shaanxi, western Gansu and most of Xinjiang being 1℃ to 2℃ higher.

　　Combined with the comparative analysis of the weather conditions last year, Gao Hui said that the high temperature situation this summer is expected to be weaker than last year in terms of the duration, peak intensity, high temperature range and cities covered by extreme high temperature above 40℃.

　　"But this year’s high temperature duration and high temperature range are still more than those in summer." Gao Hui suggested that attention should be paid to the adverse effects of high temperature on human health, and relevant departments should make preparations in advance to meet the peak and ensure energy supply in summer.

　　With the high temperature, there is drought. Like the trend of high temperature, the National Climate Center predicts that the overall scope and intensity of drought this year will be weaker than last year, but in some areas, such as the middle reaches of the Yangtze River, there is a greater possibility of persistent drought. In the lower reaches of the Yangtze River and other places, with the rapid development of high temperature after the rainy season, evaporation will increase sharply, which may lead to the rapid development of staged drought.

　　"On the whole, the climate of China is greatly influenced by the superposition of ocean and land surface factors, which will increase the uncertainty of future spring and summer evolution. On the other hand, under the background of global warming, the number of extreme weather and climate events is increasing, which also increases the uncertainty and difficulty of climate trend prediction." Gao Hui said that the meteorological department will continue to closely monitor the key systems affecting climate prediction and the changes of weather and climate characteristics, strengthen consultation and judgment, and timely revise the climate prediction opinions.
