中文摘要: 这是一个对GFS数值预报产品进行解释应用的方法。将支持向量机（SVM）回归方法应用于近海和登陆热带气旋（TC）的强度预报。从其本身强度，影响范围内气象因子情况，地形因子等三个方面，设计相关因子，建立预报模式，用来预报12、24、36、48、60和72 h的TC强度。总体上模式强度预报结果与中央气象台的预报结果相近，优于气候持续法的预报；趋势预报优势明显，可高出7～12个百分点。表明可以成为台风强度预报的另一个工具，投入业务应用。

Abstract:This is an interpretation technique for numerical weather prediction (NWP) products of GFS. In this paper the support vector machine (SVM) was employed to forecast the intensity of offshore and landing tropical cyclones (TC). According to the TC intensity, meteorological environment and topographical factors, we designed related factors and built a forecasting model which was used to forecast the intensities of TC in 12, 24, 36, 48, 60 and 72 hours. The predicting precision by SVM is closer to the forecast by the National Meteorological Centre of CMA and all predictions are superior to that by the method of climate persistence. The trend prediction of TC has obvious advantages and can improve forecast precision by 7%-12%. All these indicate that SVM is a better method and can be applied to TC intensity forecast in operations.
