| 摘 要： | 采用Ｔ２１Ｌ５大气环流模式，详细探讨了冬季西北太平洋海表温度异常对太平洋风暴轴的影响。结果表明：冬季西北太平洋暖海表温度异常能显著增强异常区北侧及下游地区的斜压性，天气尺度扰动方差、扰动动能以及涡动热量通量等也在此风暴轴入口区得到增强，由此揭示出外热源强迫对太平洋风暴轴的维持和发展起重要作用。

| Abstract: | The winter NW Pacific SSTA effect on the Pacific storm track is investigated in detailin the context of the T_21L_5 GCM. Results show that warm SSTA can give rise to dramatically in-creased baroclinicity on the north side of the anomaly area and downstream of it and to cause syn-optic scale perturbation variance,disturbance kinetic energy and eddy heat flux to be intensifiedat the entrance of the storm track,thereby revealing the important role of thermal forcing in themaintenance and development of the track. |
