Meridional Energy Transport in Experiment S1200

In experiment S1200, dry static energy transport is larger than latent heat energy transport (Figure 1a, b). The distribution of dry static energy transport shows that the magnitude of transport is smaller than that in experiment S1380 but the contributions from each component is similar. The magnitude of latent heat energy transport is tenth smaller than that in experiment S1380 since atmospheric water vapor contents largely decreases. The equatorward transport is remarkable in the low latitude region from 20 latitude north and south, and the poleward transport is remarkable in the high latitude region. Due to this characteristics, there are two peaks in the total transport profile. Comparing to the result in experiment S1380, the contribution by meridional mean circulation is larger. Unfortunately, the difference between the result in experiment S1200 and that in experiment S1380 has not yet been examined.
