    We advance the hypothesis that regional characteristics of the East Asian Summer Monsoon (EASM) result from the presence of non-linear coupled features that modulate the seasonal circulation and rainfall at the intraseasonal timescale. To examine this hypothesis, we undertake the analysis of daily EASM variability using a non-linear multivariate data classifying algorithm known as self-organizing maps (SOM). Based on an analysis of the various SOM nodes, we identify 4 major intraseasonal phases of the EASM. The first node describes a circulation state corresponding to weak tropical and subtropical pressure systems, weakened monsoonal winds, and cyclonic upper level vorticity. This mode that is related with large rainfall anomalies in South East China and Southern Japan is identified as the Meiyu-Baiu phase. ... 전체 초록 보기
