Chengdu lies in the mountainous terrain of southwest China, where a humid subtropical climate and complex topography combine to funnel moist air into intense, localized downpours, especially through the summer rainy season.
Sitting on the fertile Chengdu Plain, ringed by mountains that trap moisture, the city experiences frequent but often localized heavy rain events. Steep terrain means rainfall runoff concentrates quickly into streams and rivers around Sichuan, so radar-based tracking of individual storm cells is especially valuable for anticipating flash flooding in low-lying districts.
