利用观测资料分析了冬季太平洋海表温度异常对风暴轴和急流的影响。结果表明：在冬季黑潮区域正ＳＳＴ异常时，风暴轴和急流均明显北移，并且风暴轴的强度在入口区显著增强，急流核的中心强度却变化不大；而在冬季赤道中、东太平洋地区正ＳＳＴ异常时，风暴轴和急流主要向东南方向明显扩展，强度也在太平洋中东部显著增强，但急流核的中心强度同样变化不大。进一步分析显示，急流的位置和强度变化主要受热带与副热带温度梯度大小变化的影响，而风暴轴的位置和强度变化不仅与急流有关，还主要与非绝热加热效应所直接引起的斜压性增强密切相关。
The effects of the winter Pacific anomalies on the storm turbulence and the rapids are analyzed using the observed data. The results show that both the storm axis and the jet stream move northward obviously during the positive SST anomaly in the winter Kuroshio area, and the intensity of the storm axis increases significantly in the entrance area while the core intensity of the jet stream does not change much. In the winter, When positive SST anomaly in the Pacific Ocean, the storm axis and the rapid stream mainly expand to the southeast direction, and the intensity also increases significantly in the central and eastern Pacific, but the center intensity of the jet stream also changes little. Further analysis shows that the location and intensity of the rapids are mainly affected by changes in the magnitude of the temperature gradient in the tropical and subtropical regions. The changes in the location and intensity of the storm axes are not only related to the rapid current but also to the baroclinic stress caused by the nonadiabatic heating effect closely related.
