<p class="MsoNormal"><span lang="EN-US">I am having some issue trying to create an ensemble script with ncl, the idea is to take 3 different wrfout each one has a different scheme and used to do a 1hr accum precipitation average. On the attached file you can
 see I got almost everything ready but get stock at the end with the WRF ncl function wrf_countour this function needs the  ( file , wks, prep_tot_ens, opts_r) but as you see I have 3 a ‘s, a1 is from Schem 1, a2 from Schem 2, a3 Schem 3. So I cant not use
 it with the wrf_countour function so I am a little bit lost I am new with NCL and I got this running with GRADS.<u></u><u></u></span></p>
