| 摘 要： | The spatio-temporal characteristics of typhoon precipitation over China are analyzed in this
study. The results show that typhoon precipitation covers most of central-eastern China. Typhoon
precipitation gradually decreases from the southeastern coastal regions to the northwestern mainland. The
maximum annual typhoon precipitation exceeds 700 mm in central-eastern Taiwan and part of Hainan,
while the minimum annual typhoon precipitation occurs in parts of Inner Mongolia, Shanxi, Shaanxi and
Sichuan, with values less than 10 mm. Generally, typhoons produce precipitation over China during April
– December with a peak in August. The annual typhoon precipitation time series for observation stations
are examined for long-term trends. The results show that decreasing trends exist in most of the stations
from 1957 to 2004 and are statistically significant in parts of Taiwan, Hainan, coastal Southeast China and
southern Northeast China. The anomaly of typhoon precipitation mainly results from that of the general
circulation over Asia and the Walker Cell circulation over the equatorial central and eastern Pacific.
Typhoon torrential rain is one of the extreme rainfall events in the southeastern coastal regions and parts of
central mainland. In these regions, torrential rains are mostly caused by typhoons.
