earthlight Posted October 5, 2012 Author Share Posted October 5, 2012 You can see a comparison of the two using GEMPAK scripts. The 15km RGEM is first, and the upgraded 10km 4DVAR RGEM is second. h/t baroclinic_instability. Link to comment Share on other sites More sharing options...
Dark Energy Posted October 5, 2012 Share Posted October 5, 2012 Yea, I noticed the PSU ewall it all messed up because of this for the RGEM. I hope they get to fix it. Link to comment Share on other sites More sharing options...
Sundog Posted October 5, 2012 Share Posted October 5, 2012 I would love to see the gems verification scores as we progress through fall. Imagine it becomes one of our most reliable models? The more the better. Link to comment Share on other sites More sharing options...
ag3 Posted October 5, 2012 Share Posted October 5, 2012 I would love to see the gems verification scores as we progress through fall. Imagine it becomes one of our most reliable models? The more the better. Rgem was already a good model for qpf when convection wasn't involved. It suffered greatly from convective feedback. Hopefully, this upgrade corrects that issue.
