Fwd: [Wrf-users] warning message when runing wrf-nmm

[Jamie Wolff]

Hi Eric,

The WRF-NMM does support one-way nesting in the current release.  It does not require running 'ndown' - that is for ARW only.  You are correct, v3.0 will have a feedback switch similar to ARW to run two-way nesting.

: The current release of WRF-NMM does not support running nests at the same time as the coarse domain. NMM nests are one-way and have to be run after running WRF on the coarse domain and then running 'ndown'. Then run WRF on the nest using the lateral boundary conditions produced by ndown. As far as I know, the next WRF release 3.0 is supposed to have two-way interactive nesting for NMM, and hopefully a feedback switch (as is the case with ARW) that allows users to do either two-way interactive nesting or one-way nesting in a single WRF run without having to use ndown.

: Hello wrf users,

: I am running WRF-NMM using WPS to preprocess my GFS real case. When I attempt to run the model on multiple domains, unlike on a single domain, warning message has been seen in rsl* files each time when opening a history file for the nested domain, the run was successful though.

: WARNING in nl_get_adjust_output_times: adjust_output_times applies to all domains. First arg ignored.
