【摘要】 本文主要讨论与8111号台风的生成和移动有关的影响系统,发现:高层冷涡不仅提供了有利于热带扰动发展的背景条件;而且还影响其路径。移过其北面的沿TUTT延伸的二次高层冷涡,使8111号台风离开引导气流发生偏转,出现一次复杂路径。在影响台风的生成和路径中,南亚的越赤道气流和印度的季风气流,如同高层冷涡一样具有重要的作用。更多还原

【Abstract】 In this paper, the initiation and track of Roy. a storm over the South China Sea. and its relation to surrounding systems are mainly discussed.It has been found that the upper cold vortices not only provided a favourable environment for the initial development of Roy. but also affected its track. Two upper cold vortices propagating along the TUTT and passing by the north of Roy caused the storm to deflect from the steering currenlts resultant in a complicated track In affecting the initiation and track of storm, the cross-equatorial currents over the South Asia and the monsoon currents coming from India also play important role same as upper cold vortices.更多还原
