Thread starter TyBuck Start date Jan 11, TyBuck New member. The plots attached show a handful of variables of interest where some clear features are present: 1. The town of Lubbock itself centre of the domain. Odd speckle effects which create an almost static like appearance. Can anyone explain what's going on here?
Attached is the namelist. Thanks for the help! Ming Chen Moderator Staff member. Hi, Ty, In your namelist. Can you change to Noah or NoahMP and try again?
I also tried a fixed colour scale to see if the effects were actually small and being automatically populated due to the automated colour scaling, but that didn't work either. Any ideas? Neither effect seems realistic. This is the first high-resolution domain I've ran focussed on an urban area since upgrading to WRF4. The effect is also replicable on other machines, so it doesn't seem like it's an isolated problem. Thanks, Ty. I think I've found the culprit.
So, for some reason, the simulation is doing something odd with the landuse. Digging into this a little more, I looked into near-surface variables outputted in wrfout files compared to interpolated near-surface variables using WRF-Python. Attached is an example, where the interpolated u10 clearly shows the town of Lubbock, but it looks smoothed and more realistic.
