研究了西北太平洋夏季风特征及其季风槽结构对台风生成的影响。
The influence of Northwest Pacific summer monsoon(NWPSM) characteristics and the structure of monsoon trough on typhoon genesis is studied.
西风槽为降强水提供动力及冷暖空气,台风为强降水提供水汽。
West wind trough provided power and cold - warm air for this strong precipitation, typhoon provided vapors.
主要影响系统为登陆台风、西风低槽和低空急流。
The main affecting systems include landfall typhoon, low-level jet stream and west trough.
台风及西风槽强度的改变将直接导致中尺度系统强度的变化,从而造成降水强度的不同。
Furthermore, intensity changes of westerly trough would directly lead to intensity changes of mesoscale systems and thus lead to different rainfall.
以一个在陆上长久维持并最终演变成温带气旋的登陆台风“麦莎”为研究对象,通过对其北上变性过程的分析发现,台风与中高纬西风槽的相互作用使得冷空气侵入是其变性加强的原因。
Through the analysis, it is shown that the Matsa s extratropical transition and the re-intensification are due to the intrusion of cold air from the upper-level trough into the typhoons circulation.
低层水汽输送,造成中纬度暴雨区强水汽辐合和不稳定能量积聚,故槽前降雨的强度与其南方台风东侧的水汽输送有着相当密切的关系。
The results show that typhoon intensity can have influence on the water vapor transport to mid-latitude area by the southeasterly jet on the east of the typhoon.
不同台风路径下,“角流”和背风槽的位置和范围不同。
Along different category of tracks, the location and scope of "corner flow" and leeward trough were different.
不同台风路径下,“角流”和背风槽的位置和范围不同。
Along different category of tracks, the location and scope of "corner flow" and leeward trough were different.
