Abstract
In this study, the maximum wind speed (WSmax) changes across China from 1956 to 2004 were analyzed
based on observed station data, and the changes of WSmax for 2046–2065 and 2080–2099 are projected using
three global climate models (GFDL?CM2?0, CCCMA?CGCM3, and MRI?CGCM2) that have participated
in the IPCC Fourth Assessment Report (AR4). The observed annual and seasonal WSmax and the frequency
of gale days showed obvious declining trends. The annual WSmax decreased by approximately 1.46 m s
?1 per decade, and the number of gale days decreased by 3.0 days per decade from 1956 to 2004. The amplitudes
of the annual and seasonal WSmax decreases are larger than those of the annual and seasonal average wind
speeds (WSavg). The weakening of the East Asian winter and summer monsoons is the cause for the distinct
decreases of both WSmax and WSavg over the whole China. The decrease of WSmax in the southeast coastal
areas of China is related to the reduced intensity of cold waves in China and the decreasing number (and
decreasing intensity) of land-falling typhoons originated in the Northwest Pacific Ocean.
The global climate models GFDL?CM2?0, MRI?CGCM2, and EBGCM (the ensemble of above mentioned
three global climate models) consistently suggest that the annual and seasonal WSmax values will
decrease during 2046–2065 and 2080–2099 relative to 1981–2000. The models also suggest that decreases in
WSmax for whole China during 2046–2065 and 2080–2099 are related to both the reduced intensity of cold
waves and the reduced intensity of the winter monsoon, and the decrease in WSmax in the southeast coastal
areas of China is corresponding to the decreasing number of tropical cyclones over the Northwest Pacific
Ocean in the summer during the same periods.
