| 摘 要： | 采用Ｔ４２Ｌ９大气环流模式，研究了冬季赤道西太平洋海表温度异常对太平洋风暴轴的影响。结果表明：冬季赤道西太洋正ＳＳＴＡ能显著增强风暴轴区域在气尺度扰动的强度，与风暴轴发展有关的涡动热量通量和动量通量也在风暴轴的入口区得的增强。

| Abstract: | The T 42 L 9 GCM is adopted to investigate in detail the effect of equatorial west Pacific (EWP) SSTA on the Pacific storm track during winter. Results show that the warm SSTA is responsible for appreciably intensifying the synoptic scale perturbation vigor in the track region and the track development associated eddy heat/momentum fluxes get enhanced at the track entrance region as well, thus revealing a crucial role of low latitude external heat forcing in the maintenance and development of the track. |
