Time Evolution of the Precipitation Distribution in Experiment S1380

The characteristic features of the results of Experiment S1380 are that 1) eastward propagating disturbances that probably have their origin in the baroclinic instabilities exist in the mid-latitudes and 2) vortex disturbances sometimes migrate from the equatorial region to mid- and high latitudes. The disturbances that migrate into mid- and high latitudes from the equator are not always present, and it can be presumed that most of the precipitation near 40° latitude north and south is caused by baroclinic disturbances.
