k. Characteristics of Atmospheric Disturbance

Meridional thermal energy transport increases with an increasing solar constant. The increase in energy transport is primarily attributable to latent heat transport by disturbances. Here, the nature of the disturbances that are responsible for energy transport from low to high latitudes will be examined.

The precipitation distribution of Experiment S1570 shows numerous disturbances that migrate from the tropics to mid-latitudes. The disturbance activities in this experiment are enhanced compared to the case of Experiment S1380. It can be presumed that such increased disturbance activities are the cause of the increased latent heat transport associated with an increasing solar constant. In fact, an examination of the distribution of the vertically integrated specific humidity (precipitable water) reveals that air masses with high water vapor content migrate from the low to high latitudes and air masses with low water vapor content migrate from the high to low latitudes. Although not illustrated in the figure, all these disturbances possess vorticity.
