摘要

摘要: 利用0519号"龙王"台风SAR遥感图像,结合NCEP/QSCAT混合风场海面风向反演了高分辨的台风海面风速。基于高分辨率的SAR台风海面风场的风速剖面,对台风期间台湾海峡及周边海域海面风场的小尺度特征及变化进行了分析,结果表明,地形对风场特征的形成有显著作用,它导致台风海面风场结构发生变形以及澎湖列岛附近低风速尾流区、台湾岛的中央山脉北端下风面"角流"区和台湾岛西北海岸背风槽(或诱生低压)等现象的形成及台风期间福建省沿海区的大风天气。

Abstract: High resolution sea surface wind speeds of typhoon were retrieved by using the No.0519 "Longwang" typhoon SAR image combining with the wind directions from the blended NCEP/Q SCATsea surface wind data.And also the profiles of high resolution SARsea surface wind speeds were used to analyze the features and mechanism of sea surface wind fields around the Taiwan Strait during the typhoon period. The results showed that the geography had prominent effects on the formation of wind fields features;it caused some interesting phenomena,such as the deformation of typhoon,the formation of leeward trough, corner flow and the downstream of the tips.
