China tropical cyclone rainfall climatology

China is a mountainous country, which leads to rapid dissipation of cyclones that move inland as well as significant amounts of rain from those dissipating cyclones. Typhoon Nina in 1975 caused the collapse of two huge reservoirs and ten smaller dams when 1062 mm (41.81 inches) of rain fell in Henan Province during a 24‑hour period. Super Typhoon Carla was the wettest tropical cyclone on record for mainland China. Since 1957, there has been a downward trend in tropical cyclone rainfall for the country.
