中文摘要：

利用NCARCAM3．1模式及NCEP／NCAR（version1）再分析资料计算出来的几种大气热源分布情况，分别讨论亚洲各地区和南半球上空夏季大气加热场（热源或冷源）对东亚季风环流系统和印度季风环流系统形成的影响。结果表明：（1）东亚地区上空的大气热源和澳大利亚冷源与东亚夏季风环流关系密切，东亚大陆上空及西太平洋上空的非绝热加热可以激发北半球副热带季风系统（例如副热带高压系统），而南海上空的大气热源和南半球冷源是形成南海热带西南季风和澳大利亚反气旋及越赤道气流的主要机制；（2）亚洲地区西部和对应的南半球印度洋非绝热加热与印度夏季风环流关系密切，而对东亚夏季风影响很小。孟加拉湾的热源可使印度西南季风向东延伸，而副热带大陆热源也是北半球副热带高压系统形成的主要机制。

英文摘要：

Based on the NCAR CAM3.1 model and the distribution of heat sources calculated by NCEP/NCAR （version 1） reanalysis datasets, the impact of atmospheric heat source （sink） distribution over Asia and the Southern Hemisphere on East Asian summer monsoon and Indian summer monsoon is investigated. The results show that： Firstly, the distribution of atmospheric heat source over East Asian region and heat sink over Australia have close relations with East Asian summer monsoon, the heating over the East Asian continent and West Pacific can in- duce the subtropical monsoon system over the Northern Hemisphere （for example the subtropical high）, and the heating over the South China Sea and the cooling over the North Australia are the major mechanism for the tropical Southwestlies monsoon over the South China Sea, the anticyclone over Australia, and the cross equatorial flow;Secondly, the heating over the western part o{ Asian region and Indian Ocean and that south of the equator connect with Indian summer monsoon very well, however, the impact on East Asian summer monsoon is weak. Heating o- ver the Bay of Bengal can induce Indian southwestlies monsoon to extend eastwardly, heating over the subtropical continent is the major mechanism for the subtropical high over the Northern Hemisphere.
