摘要:
台风的灾害往往是由暴雨引起的，对台风螺旋雨带特征的研究有利于提高对台风天气的预报水平。近年来，国内外学者对螺旋雨带的形成理论提出了相应研究。本文基于WRF模式对2014年第12号台风“娜基莉”过程进行了模拟研究，对螺旋雨带强度的变化特征进行了分析。结果表明：螺旋雨带最大降水区呈现围绕台风中心逆时针旋转的特点；螺旋雨带的结构与台风强度具有良好的对应关系。
The major damage of typhoon is mainly caused by heavy rain; related research about the characteristics of typhoon spiral rain-band is helpful to improve the ability of typhoon forecasting. Recent years, scholars at home and abroad have got some theories about the formation of typhoon spiral rain-band. This article made a simulation of the No. 12 typhoon “Nakri” happened in year 2014 using WRF model. Then characteristics of the change of spiral rain-bands are analyzed. All the studies showed that, the maximum precipitation zone of spiral rain-band presented clockwise trend. The structure of spiral rain-band corresponds well with the wild field.
