南海夏季风爆发迟早的影响因子分析

Studies on Factors Affecting the Early or Late Onset of South China Sea Summer Monsoon

本文通过统计分析、合成分析和相关分析,探讨了影响南海夏季风爆发迟早的因子。研究发现,这些因子包括海温的变化,热带地区对流的活动以及大气环流的形势等,它们在南海夏季风爆发早晚年间存在着很大的差异。

the factors affecting the onset of the South China Sea summer monsoon are studied from 1950 to 1997 based on the methods of statistics analysis、composite analysis and correlation analysis. The results show that the main affecting factors, such as the transformation of SST, OLR conduction over tropical Indian ocean and tropical pacific ocean, and the general circulation, have obvious distinction between the early onset year and the late onset year. All these factors work in coordination and decide an early or late onset of South China Sea summer monsoon.
