中文摘要：

台风风场结构对台风预报和灾害评估具有重要的意义。作为目前仅有的高水平分辨率台风风场结构资料——NOAA/NESDIS全球多平台热带气旋风场资料（MTCSWA）,虽然在北大西洋地区已经利用HWind资料进行了评估,但在西北太平洋地区还没有相关的评估和验证。利用自2008年以来影响浙江的3个台风的沿海海岛站和浮标站风场资料,以及相关的卫星资料,对MTCSWA资料进行了初步评估。结果表明MTCSWA资料所表现的台风非对称结构与卫星观测一致,MTCSWA资料的风速与实际观测风速的平均绝对误差（MAEs）为47m/s,与北大西洋的误差（50m/s）相当,但在台风内核区域（大风半径附近）风速被低估,MAEs达74m/s。

英文摘要：

The typhoon wind field structure is of vital significance to its forecast and disaster assessment. As the only typhoon wind field structure data with high horizontal resolution, NOAA/NESDIS multiplafform tropical cyclone surface wind analysis （MTCSWA） has been evaluated by H ＊ wind data in the North Atlantic region, while related assessment and verification has not been carried out in the Pacific Northwest. In this work, three typhoon cases influencing Zhejiang since 2008 were chosen. With island stations and buoys wind data and related satellite data, we made a preliminary evaluation of MTCSWA. The results show that the performance of the MTCSWA data of typhoon asymmetric structure is consistent with that of satellite observations, with the mean absolute error （MAEs） of MTCSWA wind speed at 4. 7 m./s relative to the observed wind speed, which is equivalent to the MAEs in the North Atlantic （5 m/s）. However, the gale of typhoon kernel （near the maximum wind radii） is underestimated, with the MAEs as high as 7.4 m/s.
