Typhoon is a great natural disaster in the world. The accuracy of its path prediction is particularly important. In the conventional data-sparse tropical ocean, satellite images are the main tool to monitor tropical cyclones. Cloud track wind technology which by way of the characteristics of the clouds and clear zone to get the AMVs (atmosphere motion vectors), to a certain extent, makes up for the restrictions of the study of the ocean typhoon path due to the lack of observation data. This study combines with the gradually mature application of the satellite derived wind to typhoon prediction and also sums up the contributions of the cloud motion wind technology in improving the prediction of the typhoon path, such as the Encryption of observation data, Typhoon Center Orientation, Numerical optimization of an objective analysis of initial and field, typhoon Bogus model of man-made structure and Development and Non-development Tropical Cyclones revealed by high density cloud motion winds. Encryption observation over the sea (especially the upper atmosphere) provides valuable information for studying the dynamic mechanism of tropical cyclones. It also has an important contribution of the typhoon simulation, which has enhanced the analysis level of transition of tropical cyclones and abnormal path, and provided a wealth of wind data for the study of new typhoon track prediction methods, such as Bogus. At the same time, it also prospects a further study in the practical application of this content.
