Abstract:In July 2026, the mid- and high-latitude circulation in the Northern Hemisphere exhibited a predominantly four-wave pattern. The Northwest Pacific subtropical high was located farther north than normal and extended westward in stages, and the rainy season in North China began earlier than normal. The national average precipitation was 122.8 mm, 1.0% more than normal. The above-normal precipitation occurred mainly in eastern Northwest China, Northeast China, eastern and southern North China, central regions south of the Yangtze River, and South China. Six widespread precipitation events and four severe convective weather events occurred during this month. Extreme daily precipitation was recorded at 88 national meteorological observation stations, among which the daily precipitation at 22 stations exceeded the historical records. The national average temperature was 23.5℃, 1.3℃ warmer than normal and ranked as the second highest for the same period since 1961. The national average high-temperature days were 5.7 d, the third most for the same period on record. Daily maximum temperatures at 225 stations reached the extreme high-temperature threshold, with 40 stations seeing the temperature reach or exceed their historical records. Specifically, the maximum temperature at Dongkan Station in Turpan of Xinjiang was up to 49.8℃. In addition, five typhoons formed successively over the Northwest Pacific and the South China Sea, three of which made landfall in China bringing strong winds and heavy rainfall to parts of the country. Severe convective activities were relatively intense. From the evening to the night of 6 July, three tornadoes occurred in eastern Hubei, two of which were of EF3 level and one was of EF1 level.
