【摘要】 利用 L9R1 5气候谱模式 ,就热带太平洋—印度洋夏季海温异常对亚洲夏季风的影响进行了数值研究。结果表明 ,夏季热带太平洋和印度洋海温正异常时 ,不仅能造成热带地区大气环流和降水的同时性响应 ,还能导致东亚夏季风和南亚夏季风的一致减弱 ,两者的影响是同号的 ,但并不是两者单独影响的线性叠加。由此给出了亚洲夏季风与热带太平洋—印度洋海气系统的同期关系更多还原

【Abstract】 L9R15 climate spectrum model is employed to investigate the effect of summer SSTA in the equatorial Indian Oecan and Pacific on Asian summer monsoon.It’s found that the positive SSTA in summer in the tropical Indian Ocean or Pacific can,not only cause the response of atmospheric circulation and precipitation in the tropical region,but also lead to the weakening of east Asia and south Asia summer monsoons.However,the output with SSTA imposed in two waters together is not a linear sum of the output with SSTA imposed individually in two waters.As such, the schematic map is proposed to demonstrate the simultaneous relationship between the Asian summer monsoon and the atmosphere-ocean system in the tropical Indian Ocean and Pacific.更多还原
