Abstract

Indonesian Throughflow (ITF) transport change under the global warming scenario has been investigated using a coarse resolution global ocean circulation model based on the HYCOM (Hybrid Coordinate Ocean Model). Two cases of atmospheric forcing have been applied to compare the ITF transport change, one is adopted from the daily surface heat and momentum fluxes of ERA-interim data from 1989 to 2010 for the 20th century and the other is the monthly forcing from MIROC 3.2 hi-resolution results for the A1B scenario during 21st century. For the surface flux correction, the sea surface salinity has been relaxed to the climatological data with a time scale of 30 days and the long wave correction has been applied to the surface thermal radiation flux. Comparison shows that the ITF transport is decreased in a warming climate. The reasons of this decrease of ITF transport and its impact have been discussed.
