摘要

用为时期的 NCEP/NCAR 分析数据 1957 2001,季节的转变在亚洲澳大利亚人的季风区域大规模垂直地综合的潮湿运输(VIMT ) 展示的 climatological 在这篇论文被调查。到夏天的从冬季的 VIMT 的季节的转变的基本特征是夏日的建立“大潮湿河”模式(说出 GMR 模式)并且它的东方扩大,与发生在“一些关键时期”的一系列 climatological 事件联系了,它在中间的5月在中间的三月,在在迟了的4月的斯里兰卡附近的低 VIMT 旋涡的活动,和华南海夏季风的发作在印度支那半岛上包括著名南方的 VIMT 的出现,在其它之中。在到冬季的从夏天的转变期间,然而,特征被建立主要展出在东方位于热带区域的 VIMT 带,由发生在“关键时期”的一些事件伴随了。当在季节的变化过程期间从西的 VIMT 的南方的迁居看了时,进一步的分析揭示印第安人和东方亚洲季风区域之间的大差别,根据哪个亚洲季风区域能容易沿着印度支那半岛的西方的方面被划分成二部分,它可以也表示在二个区域之间的不同形成机制。

The basic features of the seasonal transition of VIMT from winter to summer are the establishment of the summertime "great moisture river" pattern (named the GMR pattern)and its eastward expansion, associated with a series of climatological events which occurred in some "key periods", which include the occurrence of the notable southerly VIMT over the Indochina Peninsula in mid March, the activity of the low VIMT vortex around Sri Lanka in late April, and the onset of the South China Sea summer monsoon in mid May, among others. However, during the transition from summer to winter, the characteristics are mainly exhibited by the establishment of the easterly VIMT belt located in the tropical area, accompanied by some events occurring in "key periods". Further analyses disclose a great difference between the Indian and East Asian monsoon regions when viewed from the meridional migration of the westerly VIMT during the seasonal change process, according to which the Asian monsoon region can be easily divided into two parts along the western side of the Indochina Peninsula and it may also denote different formation mechanisms between the two regions.
