摘　　要：采用NCEP/NCAR再分析资料,计算了夏季哈德莱环流（ H. C.）强度,分析了夏季H. C.强度年际、年代际变化特征,以及亚洲季风区夏季水汽输送的气候特征,并研究了夏季哈德莱环流强度与亚洲季风区水汽输送的关系。结果表明,1979-2010年夏季南半球H. C.强度有明显增强趋势,同时也有明显的年际变化。索马里东部洋面和印尼东部洋面是南半球水汽北转输入亚洲的重要区域；夏季南半球哈德莱环流强度与索马里东部洋面和印尼东部洋面的经向水汽输送呈显著的正相关关系,与在我国中东部—南海南部、阿拉伯海东南部的经向水汽输送呈显著的负相关关系。Using NCEP/NCAR reanalysis data, Hadley Circulation intensity in summer was calculated, the annual variation characteristics were analyzed, as well as the climate features of water vapor in Asian monsoon region. The relationship between H. C. intensity and water va-por in Asian monsoon region was studied. The results showed that during the summer of 1979 to 2010, the intensity of H. C. in the southern hemisphere was significantly increased, and there was a significant annual variation. The eastern ocean of Somalia and Indonesia was an im-portant region of the southern hemisphere water vapor transport to Asia;the intensity of H. C. in summer in southern hemisphere presented sig-nificant positive correlation with meridional water vapor transport in eastern ocean of Somalia and Indonesia, showed significant negative corre-lation with meridional water vapor transport in middle east of China-south of the Nanhai Sea, southeast of Arabia sea.
