Yang Shi Xin Wen· 2025-06-17 11:36
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].

Core Viewpoint - The "Three Summers" period is critical for crop planting, with the northern regions entering the main wheat harvesting phase in early June. Recent weather forecasts indicate that drought conditions may ease due to expected rainfall in certain areas, although some regions will experience dry weather favorable for harvesting [1]. Group 1: Weather Impact on Agriculture - Rainfall is expected from May 31 to June 2 in drought-affected areas such as southeastern Gansu, southern Shaanxi, and southwestern Henan, which will help alleviate drought conditions, although it may temporarily hinder wheat harvesting [1] - The next ten days will see no significant rainfall in regions like northern Shaanxi, northwestern Henan, southern Shandong, and northern Anhui, which is beneficial for accelerating wheat harvesting [1][3] Group 2: Threats to Crop Yield - The two main threats during the "Three Summers" are hot winds and excessive rainfall, which can lead to reduced wheat yields and spoilage of mature crops [3] - Experts recommend scientific irrigation and foliar fertilization to enhance crop resilience against hot winds, as well as selecting appropriate crop varieties to mitigate risks from the outset [3] Group 3: Harvesting Strategies - During rainy conditions, experts advise timely harvesting and drying of wheat based on weather conditions and crop maturity to minimize losses. If conditions do not allow for drying, low-temperature mechanical drying or proper indoor ventilation should be employed [6] - To prevent sprouting of wheat heads, the use of sprout inhibitors is recommended, with a focus on harvesting varieties that are more susceptible to sprouting first [6] Group 4: Pest and Disease Management - Regions like Huang-Huai-Hai and the middle and lower Yangtze River are at risk of diseases such as stripe rust due to increased rainfall, while high temperatures and low rainfall can lead to pest outbreaks like aphids and spider mites [8] - In corn-growing areas, attention should be paid to root rot and underground pests, as well as migratory pests that can damage crops during their growth stages [8] Group 5: Water Resource Management - Water resource management is crucial during the "Three Summers" to ensure smooth harvesting. Authorities plan to enhance monitoring of rainfall, soil moisture, and crop conditions to dynamically assess drought situations [11] - Precise water resource allocation is emphasized to avoid downstream water shortages while addressing immediate drought conditions [12]
