CHARACTERISTICS OF RAINFALL AND TYPHOONS IN SOUTHEAST ASIA ASSOCIATED EITH LARGE-SCALE SEA SURFACE TEMPERATURE ANOMALIES

Abstract

 This research discuss relationship between sea surface temperature in the Pacific Ocean and the Indian Ocean and climate Southeast Asia. We used Empirical Orthogonal Function analysis and K-means method for analysis and classified 5 group based on the characteristics of sea surface temperature in the Pacific Ocean and the Indian Ocean. Then we investigated precipitation, the number of typhoon and tracks for each group. The group including the year of 2011 has high sea surface temperature in the Pacific Ocean, the Indian Ocean and the Atlantic Ocean. At that time the ratio of the number of the typhoon in the Northwest Ocean Pacific that attack the Southeast Asia is 1.4 times the average one. This research indicate predictability of the typhoon number from large scale sea surface temlperature anomalies.
