Automated typhoon identification from quikscat wind data

An automated typhoon identification algorithm using QuikSCAT wind data is developed. The histogram features of the wind speed and wind direction of typhoon is used for a coarse identification, and then a more precise identification which makes use of the circulation property of typhoon is applied to the wind data which can pass the coarse identification, so that the typhoon observed by QuikSCAT can be identified automatically. As an example, the identification method is applied to identify typhoon Morakat 2009 from a sequence of QuikSCAT wind data distributed by PO.DACC, the results show that the typhoon can be correctly identified with our method, which demonstrates the feasibility and usefulness of our method.
