Group 1 - The article discusses the occurrence of "warm zone rainstorms" in northern China, particularly during a period of continuous heavy rainfall affecting regions like Beijing and Hebei [1][5] - "Warm zone rainstorms" are characterized by strong convective precipitation triggered by various weather systems in a high-temperature and high-humidity environment, without significant cold air involvement [1][3] - The phenomenon is localized, with intense rainfall rates of 50-100 millimeters per hour, and the affected areas can be as small as a few dozen square kilometers, making forecasting challenging [1][3] Group 2 - The formation mechanism of warm zone rainstorms is linked to the weak confrontation between cold and warm air, leading to the accumulation of moisture from the summer monsoon in northern regions [3] - Unlike traditional warm zone rainstorms in southern China, these rainstorms can also occur in northern regions during critical periods, such as "July to August" [5] - The geological conditions and vegetation distribution in northern China are less capable of handling strong rainfall, increasing the risk of geological disasters like flash floods and mudslides [5]
