After 2 1 day, the high temperature in South China will develop again and expand its scope. The daily maximum temperature in Fujian, Jiangxi and southern Zhejiang can reach 39℃ to 4 1℃. What is the reason for the continuous high temperature? Global warming is the root cause of frequent high temperature and heat waves. The continuous La Nina event has provided an important climate background for the occurrence and development of high temperature in the south since June this year, especially in July, when the warm and high pressure belt in the mid-latitude strengthened and a large range of high temperature weather appeared. According to statistical analysis, in the summer after most La Nina events, the subtropical high in the western Pacific tends to be northward. Since the end of June this year, the subtropical high has moved northward, especially after Typhoon Siam moved northward in early July. The subtropical high extends westward and the Iranian high extends eastward. Combined with the mid-latitude continental high, a stable warm and high pressure zone has been formed over China, resulting in a wide range of high temperature weather.
