subtropical westerlies

It is then possible that "Kelvin cat's eyes" produced by the nonlinear critical layer is a new physical mechanism generating the subtropical high in the vicinity of the interface betWeen zonal easterlies and westerlies.

因此，非线性临界层产生的Kelvin猫眼有可能是位于纬向东西风交界面附近的副热带高压形成的一种新的物理机制。

Results show that the variation of the position and the intensity of the western Pacific subtropical high play a crucial role in going northward typhoons. Furthermore, the middle-latitude westerlies systems and the South Asian High actions have an important influence on typhoon ′ s northward movements.

结果发现，不仅西北太平洋副热带高压位置和强度变化对台风登陆北上起决定性作用，而且西风带系统和南亚高压活动有利于台风登陆后北折和持续北上也有不可忽视的影响。
