UEMS/WRF EMS Unofficial Forums

Hi all, If I wish to drop the first 6 hours of a run by setting FREQ_WRF_GRIB = 180:360, 60:360 in the post_grib.conf, the resulting grib files are using the initialization file reference time and the first forecast records are for 6 hours forecast. Is it an acceptable practice to reset the referenc...

Thanks for the hints.
I'll start tweaking the microphyisics schemes

Hi,

I'm using UEMS 20.11.3 and 19.8.1
The difference is to real observations and the lack of resolving cloud cover appear to be related to non-convective clouds.
Convection is being forecast quite accurately.

In the eastern Mediterranean area I am noticing underestimation of cloud cover by WRF. This in comparison to the cloud coverage predicted by global models (GFS, ICON, Arpege). I have tried several CU and PBL schemes resulting in only minor differences in cloud prediction. Has anyone tried to adjust ...

I ran into the same problem installing on Debian 10
The problem is in the installer script with a call to "uname" on line 2281

My workaround:
changed line 2281 to $info{hwtype} = `/bin/uname -m`;
instead of uname -i

I updated Robert on this

As far as I remember, gfsp25 and gfsp25pt and other gfs datasets switched over to FV3 on the 12 June this year.
If you have the latest version of UEMS the switch over is transparent.

It is possible to set the number of cpus and to stop the hyperthreading of an E2C instance, at least on Ubuntu distros This is what I used: edit /etc/default/grub if you want 16 cores for c3.8xlarge for e.g you'd edit: GRUB_CMDLINE_LINUX_DEFAULT="console=tty1 console=ttyS0 maxcpus=16" GRUB...

Hi,

Simply create a new domain using the command line ems_domain --create ...
Then copy the namelist.wps file from the static folder in your old domain to the static folder in the new domain (overwrite the existing namelist.wps).
Then finally run on the new domain.
