[Wrf-users] Long-run Simulation

[Tabish Ansari]

Hi Mickias,

I assume that you had your initial and boundary conditions for meteorology
for the one year that you ran the model for, in your wrfinput and wrfbdy
files. You must have produced these files through ungrib and metgrid
utilities, and must have downloaded a reanalysis or global model data like
FNL/GFS or ECMWF to create these files.

You cannot run a regional model (WRF) without initial and (more
importantly) boundary conditions. So you'll have to first run a global
model for the 30 years past and 30 years future, or alternatively contact
someone who has run it and has the output available for that period. Then
use that data (instead of FNL etc.) to create new wrfinput and wrfbdy
files. This would require a fair amount of restructuring and reformatting
of data if you want it to be processed by WPS. Once you've produced your
wrfinput and wrfbdy files for the required period, you can go ahead and run
WRF.


Good luck!
