极端降水的“另类”推手——“暖区暴雨”有哪些特点？一文了解

Group 1 - The article discusses the occurrence of "warm zone heavy rain" in northern China, particularly during a period of continuous heavy rainfall affecting regions like Beijing and Hebei [1][4] - "Warm zone heavy rain" is characterized by strong convective precipitation triggered by small to medium-scale weather systems in a high-temperature and high-humidity environment, without significant cold air involvement [4][6] - The phenomenon is typically localized, with hourly rainfall amounts reaching 50-100 millimeters, and the affected areas may only cover a few dozen square kilometers, making forecasting challenging [4][6] Group 2 - While traditionally associated with southern China, "warm zone heavy rain" can also occur in northern regions during critical periods, such as the transition from July to August [8] - The geological conditions and vegetation distribution in northern China are less capable of handling heavy rainfall, increasing the risk of geological disasters like flash floods and mudslides [8]
