Abstract

The purpose of this paper is to analyze the evolution of typhoon cloud patterns in the spatio-temporal domain using statistical learning models. The basic approach is clustering procedures for extracting hidden states of the typhoon, and we also analyze the temporal dynamics of the typhoon in terms of transitions between hidden states. The clustering procedures include both spatial and spatio-temporal clustering procedures, including K-means clustering, Self-Organizing Maps (SOM), Mixture of Gaussians (MoG) and Generative Topographic Mapping (GTM) combined with Hidden Markov Model (HMM). The result of clustering is visualized on the ”Evolution Map” on which we analyze and visualize the temporal structure of the typhoon cloud patterns. The results show that spatio-temporal clustering procedures outperform spatial clustering procedures in capturing the temporal structures of the evolution of the typhoon.
