摘要
利用2005~2007年春季的降水和MODIS云资料,探讨了祁连山东部降雨(雪)与云量、云(冰)水路径、云层厚度等参数的关系。结果表明,降雪量与低云量、低云冰水路径、低云云顶-云底气压差呈明显的正相关,低云量多、低云冰水路径值大、气压差大,有利于降雪的产生;降雨量与低云云顶-云底气压差也呈明显的正相关,低云云层越厚,降雨量越大。通过卫星遥感获取的云参量与地面实测降水资料进行对应,可以为天气预报提供重要参考,还可为人工影响天气作业提供指导。
By using the precipitation and cloud parameter data in spring from 2005 to 2007,the relation between precipitation and cloud parameter,such as cloudiness,cloud water path,cloud thickness and cloud particle radius,is analyzed.The results show that there is an obvious positive relation between snow and low cloud,ice water path for lower layer,pressure difference for low cloud.When rainfall occurs,there is an obvious positive relation between precipitation and pressure difference for low cloud.The above analysis shows that it is useful for weather forecast and weather modification by using both the precipitation data and the cloud parameter obtained by satellite remote sensing.
