[AOS08-P05] Experimental Seasonal Climate Prediction Using CFES
Keywords:experimental seasonal climate prediction, global coupled atmosphere-ocean GCM, atmosphere-ocean interaction, sea-ice variability
The atmospheric component of CFES has the resolution of T119 in the horizontal and 48 sigma-layers in the vertical with the top level placed at about 3 hPa. The oceanic component has a resolution of 1/2 degree in the directions of both longitude and latitude and 54 levels in the vertical. They are coupled every hour.
At this stage, 6-member ensemble 6-month predictions from the 1st day of March, June, September, and December have been conducted from 1983 through 2017, after 32-years of coupled spin-up integration with SST-nudging to the observed climatology. The experimental system exhibits skill in predicting SST variability in the tropical Pacific. Detailed analysis of the prediction skill, including comparison with the SINTEX-F system, will be shown in the presentation.
