用 CCM3/NCAR，一系列数字实验被设计探索海洋陆地的效果非洲阿拉伯的海印度 Peninsula-Bayof 孟加拉的交叉分布(跳) 亚洲夏季风发行量(ASMC ) 的形成上的印度支那半岛南方中国海。结果证明包括印度洋，阿拉伯的海，和部分的非洲人或 IndianSubcontinent 和附近的区域之间的热差别跳是维持印度季风发行量的主要机制。在舍弃这二个大陆的实验，印度季风系统(IMS ) 成员，即，索马里人跨 equatorial 喷气(40 ° E ) 和在阿拉伯的海上的西南的季风并且跳，几乎消失。而且， theHadley 循环主导地变弱。它也证明非洲在 IMS 上比 IndianSubcontinent 有更大的效果。然而，印度支那半岛和澳大利亚的存在加强东方亚洲季风系统(电动会计记帐机) 。在印度支那半岛和 SCS，澳大利亚和西方的太平洋之间的热对比在热带季风的形成起一个重要作用到电动会计记帐机的南方。当印度支那半岛在实验被掩盖时， thecross 赤道的流动(105 ° E 和 125 ° E ) 消失，通常在东亚上发现的西南的季风，和电动会计记帐机因此显著地被使衰弱。另外，夏天降水和地面温度的分发上的这些热对比的影响被调查。

英文摘要：

Using the CCM3/NCAR, a series of numerical experiments are designed to explore the effect of ocean-land interlaced distributions of Africa-Arabian Sea-India Peninsula-Bay of Bengal （BOB）-Indo-China Peninsula- South China Sea on the formation of the Asian summer monsoon circulation （ASMC）. The results show that the thermal difference between African or Indian Subcontinent and nearby areas including the Indian Ocean, Arabian Sea, and part of BOB is the primary mechanism that maintains the Indian monsoon circulation. In the experiment getting rid of these two continents, the Indian monsoon system （IMS） members, i.e., the Somali cross-equatorial jet （40°E） and the southwesterly monsoon over the Arabian Sea and BOB, almost disappear. Moreover, the Hadley circulation weakens dominantly. It also proves that Africa has greater effect than Indian Subcontinent on the IMS. However, the existence of Indo-China Peninsula and Australia strengthens the East Asian monsoon system （EAMS）. The thermal contrast between Indo-China Peninsula and SCS, Australia and western Pacific Ocean plays an important role in the formation of the tropical monsoon to the south of the EAMS. When the Indo-China Peninsula is masked in the experiment, the cross-equatorial flow （105°E and 125°E） vanishes, so does the southwesterly monsoon usually found over East Asia, and EAMS is enfeebled significantly. In addition, the impacts of these thermal contrasts on the distribution of the summer precipitation and surface temperature are investigated.
