摘要：

利用连续观测的云序列图像进行风场探测的技术已经较为成熟，目前主要应用于卫星云导风中，可以获取较大范围、大尺度的区域风场信息，但利用地基观测云图进行云导风方面的研究还较少。分析了地基测云仪器的发展现状，提出了采用高时空分辨率的地基红外云图，通过阈值确定云高，利用目标匹配方法、目标追踪方法进行示踪云的选择，利用快速搜索算法进行示踪云的搜索，以及地基云导风计算的方法，并分析了导风结果的质量控制思路。利用该类地基红外云图导风资料可以与常规高空风探测手段、卫星云导风资料互为补充。

Abstract:

In present, detecting the upper altitude wind by using the continuous observation of cloud images is widely used in the application of satellite cloud imagery, which can obtain a wide range and large scale wind field's information. There is little research on using ground-based cloud images to calculate cloud motion winds. A method of cloud motion winds of ground-based infrared cloud images is proposed. The development status of ground-based cloud measuring instrument is analyzed, the threshold method is designed to acquire whole sky cloud height by high spatial and temporal resolution ground-based infrared cloud image, the object matching method and object tracking method are used to choose tracking clouds, the quick search algorithm is used to search tracking clouds, and the calculation method of ground-based cloud motion winds is presented. At last the quality control ideas of cloud motion winds is discussed. Detection of upper altitude wind by the ground-based infrared cloud image, convention measurement of upper altitude wind and cloud motion wind of satellite images can supplement each other.

Key words: cloud motion winds, ground-based, infrared cloud image, cloud measuring instrument
