The heavy rainstorm from 08:00 on 17th of July to 08:00 on 23rd of July, 2021, in Zhengzhou, China. (a) The site distribution of process accumulated rainfall larger than 400 mm and less than 800 mm (black dots) and larger than 800 mm (red dots) (filled color represents altitude, units: m). (b) The variation curves of altitude (columnar shadow) and process accumulated rainfall over the Zhengzhou station 34.7°N and (c) the station 35.77°N [32].
