Temperature Trends - The middle phase of "Sanfu," from July 30 to August 8, saw significant temperature increases across most of China, with regions like eastern Sichuan, western Chongqing, and southern Shaanxi experiencing average temperatures over 4°C higher than the historical norm [3]. - As of August 7, 94 national meteorological stations in areas such as Sichuan, Chongqing, and Henan have broken local records for the highest temperatures in August, with Chongqing recording a peak of 44.2°C on August 4 [3]. Drought Conditions - Due to the combination of high temperatures and low rainfall, regions including Shaanxi, Henan, Sichuan, and Chongqing are facing severe meteorological drought conditions [5]. Future Weather Predictions - As the "Sanfu" period progresses, the subtropical high pressure is expected to shift southward, leading to increased cold air and rainfall in northern regions, which will significantly reduce high temperatures [5]. - However, southern areas, particularly the Sichuan Basin and Jiangnan, are predicted to continue experiencing extensive high temperatures, with some regions facing 5 to 8 consecutive days of extreme heat [5]. Public Advisory - Meteorological experts advise the public to avoid outdoor activities during peak heat hours and to manage indoor temperatures to prevent discomfort due to temperature fluctuations [5].

Group 1 - The core viewpoint of the articles is that the Meiyu season in China has started earlier than usual this year, with significant rainfall expected in various regions, which may alleviate drought conditions in some areas [1][2] - The Meiyu season began on June 7 in the Jiangnan and the middle and lower reaches of the Yangtze River, which is earlier by 2 and 7 days compared to the average, respectively [1] - The climate center predicts that the rain belt will shift northward, with heavy rainfall expected in the Huanghuai, North China, and southern Northeast regions in July [1] Group 2 - The climate center warns that the northward shift of the main flood season rain belt does not indicate a weakening of the Meiyu, but rather an increased risk of extreme precipitation events [2] - After the onset of Meiyu, strong convective weather such as short-term heavy rainfall, thunderstorms, and hail is expected to occur frequently, necessitating preparedness for flood prevention and geological disaster management [2] - The onset of the Meiyu season is expected to alleviate drought conditions in the eastern Southwest and Huanghuai regions, while drought in the southeastern Northwest is likely to persist due to weaker rainfall [2]

Core Viewpoint - A significant rainfall event is expected to impact multiple provinces in southern China, with the potential for severe weather conditions and secondary disasters due to the heavy rainfall [1][3][7]. Summary by Relevant Sections Rainfall Impact Areas - The core impact areas for the upcoming rainfall include nine provinces: Sichuan, Chongqing, Hubei, Hunan, Henan, Jiangsu, Anhui, Guizhou, and Guangxi [3][4]. - Rainfall is expected to be concentrated in regions such as southern Shaanxi, eastern Sichuan, western Hubei, and southeastern Henan, with potential for heavy rain from June 19 to 21 [3][6]. Rainfall Intensity and Duration - The rainfall process is characterized by a long duration and significant cumulative rainfall, with some areas receiving over 100 millimeters, and localized regions potentially reaching 200 to 300 millimeters [3][6]. - Compared to historical averages, the intensity of this rainfall event is expected to be stronger due to the influence of a strong subtropical high and cold air masses [4][6]. Weather Patterns and Causes - The formation of this rainfall is attributed to the interaction of warm and cold air masses, leading to sustained heavy rainfall across the Yangtze River basin [4][6]. - The subtropical high is expected to shift northward, facilitating the movement of warm, moist air into the affected regions [4][6]. Secondary Disaster Risks - There is a heightened risk of secondary disasters such as flash floods and geological hazards in areas with significant rainfall accumulation, particularly in eastern Guangxi, northern Hubei, and southwestern Hunan [7][9]. - The rainfall is also expected to alleviate drought conditions in several regions, including the Sichuan basin and parts of Henan, while still posing risks of rapid transitions from drought to flooding [7][9].
