Given our cap on skewness of 4.5, this corresponds to a value of wp2=7.9.  I.e. if the skewness maximizes, then the maximum wp2 is 7.9, although if skewness is zero, then wp2 is unlimited.\n\nDo these 3 ensemble members run to completion if the maximum wp3 is instead set to 1000.0?  I'm wondering how much flexibility we have in the value of the wp3 threshold.\n\nCould you please investigate whether there are any major differences in wp2 between the max_wp3=100 and max_wp3=1000 runs at around the times where the ensemble members crashed before?  If so, could you attach a few GrADS overplots of wp2 to this ticket?\n\nI'm not suggesting that we want to commit code with max_wp3 = 1000; I just think it would be worthwhile to pause and see how sensitive our runs are to the value of this threshold.\n\n"}}
