Ocean Response in Asia-Australia Monsoon Region to Increase of Atmospheric Carbon Dioxide Concentration in Climate Models

PI: Tatsuo Motoi
Institution: Meteorological Research Institute, Japan
Abstract:
The concentration of carbon dioxide in the atmosphere has rapidly increased and is still increasing due to mainly human activities. The change of atmospheric carbon dioxide concentration perturbs the climate system including the ocean. The ocean responds to the perturbed forcings, such as anomalous momentum (wind stress), heat and water fluxes at the surface, through the ocean-atmosphere-land surface interactions. The ocean conditions have larger seasonal variations in Asia-Australia monsoon region and affect significantly on life of both marine and continental species, including the human life, through energy and water cycles in the climate system. The purpose of the proposed research is to investigate the mechanism of response of the ocean in Asia-Australia monsoon region to increase of atmospheric carbon dioxide concentration by multi-model analyses. The datasets required for this research are monthly mean momentum, heat and water fluxes at the sea surface, and ocean velocity, temperature and salinity fields. The changes in seasonal variations of the fluxes in Asia-Australia monsoon region are analyzed as perturbations of forcings. The relations between the changes in fluxes and those in ocean circulation, temperature and salinity fields are investigated to detect the feedback processes which dominantly work in the climate changes. The evolutions of alteration in seasonal variation of thermocline depth and coastal-upwelling intensity are examined as key factors in the response processes.
