| 摘 要： | 卫星红外遥感亮温数据值除与地球的自转和公转存在密切关系外,还与大气环境和地理环境有密切关系。应用青海省黄河门堂观测点的降水量和水位,以及对应点地表亮温资料进行对比分析,其结果为：降水量与亮温存在可比性,在峰值时间区段内,亮温与降水量呈现明显的反向变化关系;降水量的波动变化导致地表温度的波动变化;水位、降水量和亮温属于温度对气候变化较为敏感的物理量。

| Abstract: | Not only Earth＇s rotation and revolution but also atmospheric environment and geography are closely related to the brightness temperature values of satellite infrared remote sensing.In this paper,by using of precipitation and water level in the Mengtang Yellow River observation points in Qinghai province and the corresponding surface brightness temperature data,we comparatively analyzed the relationship between brightness temperature and rainfall.Therefore,we have the following results.Precipitation and bright tenderness is related in the following respects：①The brightness temperature and precipitation showed a significant inverse relationship within peak time periods;②The precipitation fluctuations brought about the surface temperature fluctuations;③Brightness temperature is more sensitive to climate change than water level and rainfall. |
