摘要
利用卫星遥感资料对"桑美"台风进行分析,MODIS的多通道资料在确定台风中心、分析云的相态及区分高低云等方面提供了重要的监测信息。探索了臭氧与台风云顶温度的关系,得出以下结论:利用MODIS通道31的光谱特性可以判定台风的中心,利用BTD8.5-11和BTD11-12检测的云相态结果合理,通过散点图能够找出高云和低云的大致区域,并利用通道35和通道27得到验证;臭氧与台风云顶温度具有较好的相关性,臭氧通道的信息对于区分云的结构及性质具有指示意义。
The typhoon ＂Saomai＂ is studied with the satellite data.The MODIS multichannel data are proven to be able to provide important monitoring information on the typhoon eye,the cloud phase state,and the high and low clouds.The relationship between the ozone and the cloud top temperature of typhoon has been discussed.Following conclusions are obtained：the typhoon eye could be identified by the spectral characteristic of the MODIS channel 31;the detecting result of the cloud phase state with the BTD8.5-11 and BTD11-12 is reasonable;the approximate areas of the high and low clouds have been recognized through the scatter plots,and validated by the channels 35 and 27.The correlations between the cloud-top temperature and the ozone is well.The ozone information is indicative of recognizing the cloud structure and characteristics of typhoons.
