摘要
根据常规气象观测资料、GMS 5静止气象卫星的红外云图和可见光图像 ,分析了 1999年 4月 2 5至 5月 4日塔里木盆地浮尘天气。分析结果表明 ,红外云图和可见光图像能够监测盆地浮尘的变化 ,浮尘呈灰色 ,纹理均匀 ,边界清晰。浮尘区的TBB在 0～ - 15℃之间变化 ,与地面能见度有着较好的对应关系 ,大范围浮尘区的反射率在30 %～ 36 %之间 ,浮尘区反射率等值线稀疏 。
By using conventional meteorological data and the infrared and visible images of GMS-5 satellite, the floating dust weather from April 25 to May 4 in 1999 in Tarim Basin is analyzed. The results Show that the floating dust in Tarim Basin is monitored in the infrared and visible images, floating dust in it is gray with even grain and distinct verge. The T BB of floating dust area changes between 0～-15℃ and relates to ground visibility. In the reflectivity isogram chart the reflectivity of large area of floating dust is between 30%-36%. The reflectivity isogram of floating dust region is sparse, but in cloud field it is tight.
