讲座简介：

The Indonesian seas feature a wide spectrum of variations in hydrography and circulation.This study applies a simplefrequency-based time series decomposition method to the 20-year (2000-2019)model simulation,revealing the spatialdistributions of intra-seasonal,semi-annual,annual,and inter-annual variation,respectively.K-means clustering based onthe decomposed variabiliy is used to explore dynamical similarites and differences among dfferent basins of the Indonesianseas,highlighting the competing impacts of annual and inter-annual variations.The Indonesian seas lie at a "crossroadwhere the inter-annual variation dominates in a NE-SW oriented deep-ocean regime,while the annual variation prevailsin a NW-SE oriented marginal sea regime.The former is primarily associated with the ENSO induced Rossby waves fromthe equatorial Pacific Ocean,whereas the latter is driven by the local monsoonal winds.Moreover,the current profilesreveal significant differences between the main and east branches of the Indonesian Throughflow such that the interannualanomalies occur in opposite directions and that the annual variations are more prominent above(below)the thermocline in themain(east)branch.
