摘要
用 OSU 大气环流模式做了两个试验,一个为控制试验,另一个为假设中国北部(30～46°N,90～120°E)土壤湿度为饱和的湿土壤试验。结果表明,土壤湿度升高有利于西太平洋副热带高压和低空急流的加强和北抬,使得105°E以东的江淮和华北东南部地区降水减少,而105°E以西的非季风区和华北北部降水增加。
Using the OSU GCM,simulations are conducted,one being the control run and the other the assumed saturated wet soil run in North China(30～46°N,90～120°E).Results show that the increase in soil humidity contributes to the enhancement and northward shift of the western Pacific subtropical high and low-level jet,thereby causing the reduced rainfall over the Changjiang-Huaihe basins and SE North China east of 105°E,and favoring the increase of pre- cipitation over the non-monsoon region and northern North China to the west.
