摘　　要：利用由气候的全球海表温度及海冰来驱动NCAR CAM3.0模式,得到的200年控制试验结果,通过引用西北太平洋副热带高压指数和南亚高压指数,研究了该系统的自然变率特征。结果表明:(1)模拟的西北太平洋副热带高压具有年际变化和周期变化特征,各指数关系密切;(2)模拟的南亚高压具有年际变化和周期变化特征,各指数关系密切;(3)自然变率下西北太平洋副热带高压与南亚高压关系密切。Based on simulations of NCAR CAM3 forced by climatic global SSTs and sea ice,a control experiment result of 200 years is acquired,natural variety characteristics of Northwest Pacific subtropical anticyclone and South Asia High are studied by means of defined indices.Results show that(1)simulated Northwest Pacific subtropical anticyclone showed interannual variabilities and periodic characteristic,a close relation exists between indices;(2)Simulated South Asia High showed interannual variabilities and periodic characteristic,a close relation exists between indices;(3)A close relation exists between Northwest Pacific subtropical anticyclone and South Asia High under natural variability.
