摘要(Abstract)：

本文用国产卫星海洋二号散射计(HY-2A/SCAT)的数据对2012—2014年发生在西北太平洋的67个台风在台风最大风速、台风大小和结构方面进行探索性研究。结果表明,HY-2A/SCAT数据在对弱台风(风速小于20m/s)的最大风速估计整体偏高。用风速15m/s对应的半径(R_(15))定义台风大小并将台风分为大中小三个类别,得到了HY-2A/SCAT观测的台风大小的月平均分布,从台风数量的月分布直方图发现,中型台风数量最多且多发生于每年8—10月份。利用瑞金涡旋模型公式导出半径的计算公式,将HY-2A/SCAT海面风场数据相关参数代入公式求得相应半径值,与从HY-2A/SCAT数据中提取的半径R_(15)相结合进行对比分析,结果证明HY-2A/SCAT海面风场数据可以很好地应用于台风结构方面的研究。

关键词(KeyWords)： HY-2A/SCAT;台风;最大风速;台风大小;风场结构模型
