摘要:
|
通过对超强台风“鲇鱼”几个阶段路径的特点和NCEP再分析资料分析发现:台风的引导流场始终由中高层气流提供,因此要用中高层引导气流来分析其动向;其次,台风的强度有海温、高低层流场、暖湿气流的供应共同作用;再次,台风由南口进入台湾海峡后特殊的地形往往有利于台风强度的维持。 |
Using the NCEP reanalysis data,the characteristics of the path of super typhoon“MEGI”have been studied.We conclude that,firstly,because the steering flow is provided by the mid-high level airflow,we should discuss the trends of the typhoon by analysising the mid-high level steering flow;Secondly,the intensity of the typhoon is formed by the interaction of SST,high-level airflow and worm-moist flow;Finally,the special land-forms are of benefit to the maintenance of typhoon intensity after typhoon enter Taiwan Strait from south. |
