Tips and Tricks
1. If you notice that the WRF model has become unstable, you should consider to make the following changes in the namelis.input file:
(a) reduce the time-step; and/or
(b) set w_damping to 1; and/or
(c) set epssm (0.1 by default) to a higher value (e.g. 0.3)
The changes above indeed improves the stabilities in our case.
2. If there is segmentation error in runtime, you can add following line to your PBS job batch script and see if this works:
limit stacksize unlimited (for TCSH) or ulimit -s unlimited (for BASH)
