Re: History Reanalysis in WRF EMS 3.2.1 made easy [Guide]

Hi,

That seems like an excellent feature, I'm really after newer datasets such as 2008 and at a quality global resolution.

Just wondering, where is the link to the WRf EMS 3.2.1 Beta, as I cant find it on the SOO/STRC website.

Thanks,

David

New Computer - Ideas?

Hi Guys, I am looking into setting up a new mesoscale computer for work. I am looking to run between 3km and 6km resolution domains (not nested) with a domain that extends over the entire UK. At the moment the server computer being used has two quad core processors, 32GB of RAM. It takes 133 hours t...

Re: vertical levels

Hi guys, Whilst on the subject of levels does anyone know the eta coordinates for the standard 45 level configuration. I am wanting to keep most levels the same but make them finer close to the ground in the hope of better resolving the wind speed and direction. Or if anyone knows a set of good well...

Re: vertical levels

Hi, You cant change the vertical levels in the dwiz, but you can go to wrfems/conf/ems_run and go to the run_levels.conf folder. In there you can specify the vertical levels by either number of levels or you can directly specify the height of each level in eta coordinates (similar to sigma, terrain ...

Re: Using wrf ems for wind energy

Hi, Thanks again for your input. Yeah I have stopped using grads now and use unigrid IDV instead, its much easier to use and easy to get data out in excel format. I will have a look into the geogrid file options, and play about with the cumulus schemes, and probably leave the rest pretty much as the...

Re: Using wrf ems for wind energy

Hi everyone, I am just after your opinion on the following model set up for calculating 10m wind speeds in what is mainly quite complex terrain: Single domain 80x80 grid with 8km grid spacing centered on the Scottish highlands(will improve resolution and use nesting once new computer arrives :D ) nn...

Re: Problem monolithic file for grads

Hi, I had the same problem. Its due to the grib files being written with the same file name and so coppying over each other. The simple fix is just to go to the post_grib.conf file and go to the very bottom and change the file name format to: GRIBNAME = YYMMDDHHMN_CORE_dWD.grb#fFHFMFS AUXGRIBNAME = ...

Re: Using wrf ems for wind energy

Hi, I am just trying to validate my results at the moment and I don’t really understand the difference between the print data (gxout print) in the terminal and the gridded values (gx out grid) in the display. Can anyone explain how the gridded values are calculated and how the printed data in the te...

Re: Using wrf ems for wind energy

Hi,

Thats excellent, thank you again.

For the animation i found unidata idv and am using that instead.

Cheers,

Re: Using wrf ems for wind energy

Hi, Thanks for the quick reply! Excellent thank you I have got the magnitude of the resolved wind components fine now. I understood that wrf ems used pressure levels but I really wasn't sure what sort of levels to choose so that's a big help. My background is mechanical engineering btw not meteorolo...
