[ncl-talk] plotting rainfall intensity and not accumulated rainfall

[Yuqiang Zhang]

Hi Saurabh,

 

I think it could be a WRF issue, but I will answer you here.

In supplement for Saurabh's reply, if you have "bucket_mm" option turned on
in your WRF runs, you also need to add the I_RAINC and I_RAINNC

 

Something like this: 

pcp1 = a->RAINC(it-1,:,:)*(a->I_RAINC)*"bucket_mm" + a->RAINNC(it-1,:,:) *
(a->I_RAINNNC)* bucket_mm"



bucket_mm" is the setting in your WRF runs. Usually it use "100"

 

Regards,

Yuqiang

may be something like:

 

pcp1 = a->RAINC(it-1,:,:)+a->RAINNC(it-1,:,:)
pcp2 = a->RAINC(it,:,:)+a->RAINNC(it,:,:)
pcp  = pcp2-pcp1
