摘要
基于中国海洋大学卫星地面站提供的数据,通过NOAA/AMSU温度反演资料对2006年第4号强热带风暴"碧利斯"进行路径估算、结构再现、强度分析。结果表明,采用250 hPa温度场信息进行强热带风暴中心定位,可以较准确地估算台风路径;在利用卫星数据反演的AMSU-B 150 GHz通道亮温图像上叠加风场信息,可以清晰地反映台风的螺旋结构,同时利用AMSU数据反演得到的亮温距平剖面图能够很好地反映台风强度。
Based on the retrieval data of atmospheric temperature profiles from NOAA/AMSU received by the satellite ground station in Ocean University of China, the 4th Tropical Cyclone BILIS in 2006, was analyzed in terms of its track, structure and intensity. It shows good consistency with other data to track BILIS path through the temperature information at 250mb, and the spiral structure of BILIS can be seen more clearly from its brightness temperature in AMSU -B channel 150 GHz, when the related wind information has been added. The cross section of temperature anomaly can well represent the intensity.
