Lanzhou sits in China’s arid-to-semiarid northwest, where annual rainfall is comparatively low but falls in short, intense summer cloudbursts rather than steady, gentle rain.
Strung along a narrow stretch of the Yellow River valley, the city’s steep surrounding hills concentrate any heavy rain into fast-moving runoff toward the river. Dry, hard-packed or loess soil common to Gansu sheds water quickly rather than absorbing it, so a brief but intense storm can trigger flash flooding well out of proportion to the total rainfall, making live radar useful for spotting fast-developing cells.
