ID-18 :   AFES AMIP-type experiment




AFES AMIP-type experiment


By using AFES, which is an atmospheric general circulation model develped at JAMSTEC, we investigate influence of sea ice and mid- and high-latitude ocean on the atmospheric circulation from the view point of potential predictability.

Model Characteristics

The horizontal resolutions of AFES are T119 (about 100km) and T239 (about 50km).

Abstract (Brief description of the experiment contents (initial conditions, boundary conditions, etc.))
The initial condition is taken from every 1st January of a 20-year climatological expriment in which climatological-mean sea surface temperatures (SSTs) and sea ice are prescribed. There are four experiments: (i) observed SSTs and sea ice are presribed, (ii) observed SST and climatological sea ice are prescribed, (iii) climatological SST and observed sea ice are prescribed, and (iv) climatological SSTs and sea ice are prescribed. There are 20 ensemble members for each of experiments.
