    WRF hangs when running an LES at 250 m

    I have been trying to run a one day of simulations over the Java island. While Java has a complex terrain with mountain reach 3km height, the inner domain is over flat terrain. The wrf.exe hangs at 9 UTC no matter all the different combinations of schemes I have tried. I am running a 3 domain...

    How to add additional auxinput streams?

    Hi all, I would like to add some new variable inputs into WRF. For example, I need to input 10 variables, all of which are dynamically changing, and each variable has its own distinct timestep. I understand that auxinput5 can handle dynamic inputs(SST,LAI,etc), but I have more than one variable...
