基于遥感探测的不同类型降水云识别方法

降水云类型监测的手段主要有地基的新一代多普勒天气雷达和空基的气象卫星,该文介绍了利用雷达和卫星对不同类型降水云监测的原理和方法,对国内外使用神经网络法、阈值法、小波分析等方法进行不同类型降水(对流性降水、层状云降水和混合云降水)云系/云团识别的研究结果和进展进行了简要综述,主要介绍阈值法,并对两种监测手段存在的问题进行了阐述。

Review of Monitoring Methods for Rainfall Cloud Remote Sensing

Precipitation is a common phenomenon in the atmosphere. Owing to the difficulty of high spatial and temporal resolution cloud monitoring on ground, various remote sensing techniques are used in precipitation cloud monitoring. An introduction is made to the principles, techniques, and methods of rainfall cloud detection techniques, mainly the ground-based Doppler weather radar, and meteorological satellites. The findings and advances in the researches on the identification of cloud systems/clusters for different types of precipitation （including convective, stratoform-cloud, and mixing-cloud precipitation） with neural network, threshold, and wavelet analysis methods in China and abroad are reviewed, with emphasis on the threshold method. The problems encountered in use of both radar and satellite detection data are discussed.
