Core Insights - Jiangxi Province is experiencing historically high average temperatures and an increased number of high-temperature days due to extreme global atmospheric circulation patterns [1][2] - The province has recorded an average temperature of 29.1°C since June 25, which is 2.2°C higher than the historical average, marking the highest level since 1961 [1] - The drought situation has worsened, with significant reductions in rainfall and a rapid development of meteorological drought conditions affecting agriculture and public health [2][3] Temperature and Rainfall Data - Since June 25, Jiangxi has experienced 61 days with temperatures above 35°C, which is 30 days more than the historical average [1] - The average rainfall in Jiangxi this year is 1168 mm, which is 24% lower than the historical average, making it the sixth lowest since 1961 [1] - From June 25 onwards, the average rainfall has been 274 mm, which is 42% lower than the historical average [1] Drought Impact - As of early September, drought conditions have affected 583,000 people, with 100,900 hectares of crops impacted and 4,500 hectares completely lost, resulting in direct economic losses of 460 million yuan [2][3] - The drought risk is distributed unevenly, with northern and central Jiangxi facing higher risk levels compared to southern regions [2] Response Measures - Since July, Jiangxi has conducted 1,443 artificial rain-making operations, impacting approximately 118,000 square kilometers and increasing rainfall by about 4.45 billion cubic meters [3] - Meteorological authorities predict continued high temperatures, with maximum temperatures reaching 35 to 37°C in most areas from October 10 to 13, and a slight decrease expected after October 18 due to cold air influence [3]

Core Insights - Since July, northern China has experienced multiple rounds of heavy rainfall, with significant overlap in precipitation areas, particularly from July 23 to 29, where regions like Qinghai, Gansu, Inner Mongolia, Beijing-Tianjin-Hebei, and Northeast China faced heavy to extremely heavy rainfall [1][3] Weather Patterns - The recent heavy rainfall in northern and northwestern China is directly related to abnormal atmospheric circulation. The intensity of the western Pacific subtropical high has been stronger and positioned further north, creating favorable conditions for sustained heavy rainfall in the north [3] - The active tropical systems in the southern ocean during mid to late July have further enhanced moisture transport to northern regions, contributing to the persistent heavy rainfall [3] - Geographical features also play a significant role, as the terrain in regions like the Yinshan, Taihang, and Yanshan mountains facilitates the uplift and convergence of warm, moist air, leading to repeated heavy rainfall events in areas like Beijing and Hebei, resulting in significantly higher cumulative precipitation compared to historical averages [3]
