摘要
利用常规观测资料,对2015年第22号台风"彩虹"登陆前后的环流形势、探空风场和物理量场诊断分析。结果表明:强盛的副热带高压使得"彩虹"在登陆前后稳定的向西北偏西方向移动;"彩虹"在广西产生强降雨的原因是西南暖湿气流辐合和长时间维持的动力条件;"彩虹"中心经过及其东南侧的强上升运动是强降雨集中在玉林一带的主要原因。
The circulation situation, physical quantity field and sounding wind field of Typhoon " Mujigae" in 2015 were analyzed by using conventional observation data. The results show that: the strong subtropical high made " Mujigae" steadily move to the Northwest toward West when landing. The convergence of the southwest warm air and the long-lasting dynamic condition led to the appearance of " Mujigae" , and the strong rainfall in Yulin area was caused by the strong upward movement on the southeast side of Typhoon and passing-by " Mujigae" center.
