WRF Model Version 3.5.1 : Known Problems and Fixes

Nesting with 1:2 ratio:

Problem: There is a problem with nest ratio of 1:2.

Solution: We are working on resolving the problem.

Grell-Freitas Cumulus Scheme (new in V3.5):

Problem: There are 2 bugs found in one of the physics files. One bug is related to erroneous use of a computed tendency that will subsequently impact the computed rainfall rates, and the other bug is related to the forcing calculation.

Solution: Replace WRFV3/phys/module_cu_gf.F with a corrected file and then recompile the code. There is no need to do a 'clean -a' or to reconfigure.

Compilation Problems (added 11/5/2013):

Problem: There are certain compilers that have a problem with the way a couple of the calculations were written in the code for files module_bl_mynn.F and module_radiation_driver.F, causing WRF to encounter errors during compilation.

Solution: Replace WRFV3/phys/module_bl_mynn.F with a corrected file and replace WRFV3/phys/module_radiation_driver.F with a corrected file and then recompile the code.

Restart Failure when Using Sea-Ice Options (added 11/5/2013):

Problem: When using certain sea-ice options (namelist options: SEAICE_ALBEDO_OPT=2; SEAICE_THICKNESS_OPT=1; SEAICE_SNOWDEPTH_OPT=1) restarts were failing.

Solution: Replace WRFV3/Registry/Registry.EM_COMMON with a corrected file and then recompile the code. You will have to do a 'clean -a' and then reconfigure and recompile the code for this correction to work.
