Group 1: Weather Patterns and Predictions - The average national precipitation is 6.2% lower than the historical average, with the highest number of high-temperature days recorded for this period [1]. - The rainy season has started 13 days earlier than usual, leading to increased risks of frequent heavy rainfall in northern China, where flood control infrastructure is relatively weak [3]. - Southern regions, particularly the Yangtze River basin, are experiencing reduced rainfall, raising concerns about drought conditions [3]. Group 2: Rainfall Distribution and Impact - The rainfall distribution for August is predicted to be uneven, with northern and northeastern regions, as well as southern areas like Guangdong and Hainan, experiencing 20-50% more rainfall, while regions like Chongqing, Hunan, and Hubei may see 20-50% less [6]. - The increased rainfall in certain areas necessitates heightened vigilance against flood and geological disasters, especially in northern regions that have faced severe flooding in recent years [6]. Group 3: Health and Climate Mapping - The national meteorological health map is based on 30 years of data from 2,400 counties, aiming to provide a clear understanding of how weather affects health and well-being [7][9]. - The map evaluates climate comfort based on multiple factors, including temperature, humidity, wind speed, and air quality, to guide the public in making informed decisions about health and wellness [10][12].
