Figure 2.4.a. Time series of the precipitation results of 81 SCM runs (black lines) versus observational data (red line) for 30 August - 18 September 1974 GATE III are shown here. Each of the SCM runs was initialized with a temperature sounding corresponding to a different grid point of the objectively analyzed dataset; all other initialization and prescription data were identical for each run. The SCM was driven using horizontal advective forcing ("vertical flux mode").
