In the past, northern China had a mainly dry climate, and many cities in the region, with dense population, had relatively underdeveloped infrastructure to handle extreme rainstorms. Consequently, northern cities are highly exposed and extremely vulnerable to the risks brought by strong rainfalls.
Based on our model’s predictions, there will be an evident increase in annual precipitation in China in the future. In the north, for example, from 2026 to 2045, urban regions in Beijing-Tianjin-Hebei will experience an increase not only in summer precipitation but also in annual average precipitation. There will also be more torrential rains, more days of moderate and heavy rainfalls, a greater number of rainy days and an increase in maximum consecutive five-day precipitation. As urban areas expand, the risk posed by heavy rainfalls continues to expand as well.
