Core Insights - The article discusses the significant weather differences between northern and southern China, highlighting the impact of the subtropical high-pressure system on these variations [1][2]. Weather Conditions - From October 10 to 13, regions including eastern Northwest China, North China, and the Huanghuai area are expected to experience substantial rainfall, with areas like eastern Gansu and southern Shaanxi facing a high probability of heavy rain [1]. - In contrast, southern regions such as Jiangnan and South China will continue to experience high temperatures, with some areas forecasted to exceed 35°C, and local temperatures potentially reaching above 38°C [1]. Meteorological Explanation - The chief forecaster from the Central Meteorological Observatory explains that the weather patterns are influenced by the subtropical high-pressure system, which leads to clear and hot conditions in areas under its control, while regions on its periphery are prone to rainfall [2]. - The strong northward shift of the subtropical high-pressure system, combined with active cold air in the northern regions, has resulted in significant precipitation along its northern side [2]. Agricultural Impact - The ongoing rainfall in the northwest and northern regions poses risks of soil saturation and flooding, prompting experts to recommend harvesting mature crops before rain, and implementing drying and storage measures to mitigate spoilage risks [3]. - Conversely, the persistent high temperatures in southern regions are leading to soil moisture deficits, necessitating attention to soil preparation for oilseed rape planting to ensure proper seedling emergence [3].
