[Wrf-users] negative values when i plot rainfall output

[afwande juliet]

Dear Users
I am perplexed. I plotted WRF output Rainc and Rainnc and Rainnc+Rainc
My worry is that there are negative values for convective rain and when i
add convective and non convective rain.But when I plot only non convective
rain, no negative value in the scale is seen

Is the problem with my simualtions? OR how can I avoid negative values? I
am using ferret to plot
