Hello,
I am familiar with WRF model and have already used wrf restart files to continue previous simulations with extended GFS files of the same cycle. However, I was wondering if it is possible (both computationally and physically) to use the last wrfrst file of a simulation (that started with GFS cycle 00 UTC) to extend the forecast but using next GFS cycle files as input date (properly selected according to the new forecasting date). I am worried about accumulated variables and tendencies since I will be merging a initial state of the atmosphere with boundary conditions different from those used in the previous simulation.
Also, is it possible to create a hole new simulation with GFS files form different cycles from the beginning (without using restart files to merge them)? Is it a worse approach?
My intention is to use this mix of GFS files to avoid having to generate spin-up files in every situation, since using wrfrst files would already save a proper state of the atmosphere, so I could combine the latest GFS files without having to start again the simulation with a cold-start.
Thanks a lot.
