Abstract. This paper describes a novel method for hurricane trajectory prediction based on data mining (HTPDM) according to the hurricane's motion characteristics. Firstly, all frequent trajectories in the historical hurricane trajectory database are mined by using association analysis technology and their corresponding association rules are generated as motion patterns. Then, the current hurricane trajectories are matched with the motion patterns for predicting. If no association rule is found for matching, a predicted result according to the hurricane current movement trend would be returned. All experiments are conducted with the Atlantic weather Hurricane/Tropical Data from 1900 to 2008. The experimental results show that if the matching failure part is contained, the prediction accuracy is 57.5%. Whereas, the valve would be to 65% provided all matches are successful.
