Core Points - The recent weather in China shows a significant contrast between the north and south regions, with northern areas experiencing continuous autumn rain and a sharp drop in temperature, while southern regions are still facing high temperatures exceeding 35°C [1][2][3] - The temperature disparity is expected to persist in the coming days, with forecasts indicating rainfall in the northwest, north, and Huanghuai regions, while Jiangnan and parts of southern China will continue to experience high temperatures, with some areas reaching above 38°C [1][2] Weather Conditions - Northern regions, including central and northern China, have experienced heavy rainfall, with forecasts predicting moderate to heavy rain from October 10 to 13, particularly in the Sichuan Basin, northwest, north, and Huanghuai regions [2] - Southern regions, particularly Jiangxi, Zhejiang, Fujian, and parts of Hunan, are expected to maintain high temperatures, with some areas likely to see temperatures above 35°C, and specific regions reaching up to 38°C [2][3] Meteorological Explanation - The weather patterns are influenced by the subtropical high-pressure system, which causes clear and hot conditions in the southern regions while allowing for rainfall in the northern areas due to the interaction of cold air and warm moist air [3] - The recent temperature drop in northern regions is attributed to the strong presence of cold air and the subtropical high-pressure system, resulting in a significant decrease in average temperatures compared to historical norms, with some areas experiencing temperatures 2°C to 4°C lower than usual [3]

Core Points - A significant temperature contrast is observed between northern and southern China, with northern regions experiencing a drop in temperature due to cold air and rain, while southern regions continue to experience high temperatures above 35°C [1][5][7] Temperature Trends - Northern regions, including North China and Northeast China, are seeing afternoon temperatures only slightly above 10°C, with some areas like Shijiazhuang expected to reach a maximum of only 11°C, marking a significant drop for early October [1][8] - In contrast, southern regions, particularly Jiangxi and surrounding areas, are forecasted to experience high temperatures for 5 to 7 days, with maximum temperatures potentially reaching 37°C to 39°C, which is unusually high for this time of year [7][8] Rainfall and Weather Patterns - Northern China is expected to be the core area for rainfall, with forecasts indicating heavy rain in regions such as northern Shaanxi, central Shanxi, and parts of Hebei, Beijing, and Tianjin [9][10] - The ongoing rainfall in North China is characterized as unusual for October, with a long duration and significant cumulative rainfall, leading to a damp and cold feeling similar to southern autumn and winter [12] Future Weather Outlook - A warming trend is anticipated in northern regions starting from October 11, as temperatures gradually return to normal levels [12]
