July 2013 TC Inland Winds Conference Call Notes

The CIMMSE TC Inland Winds group held their monthly conference call on July 10, 2013 at 11 AM. Participants on the call were: Bryce Tyner (NCSU), Reid Hawkins (ILM), Bob Bright (CHS), Frank Alsheimer (CHS), Jonathan Blaes (RAH), John Billet (AKQ), and Michael Brennan (NHC).

Bryce led off the call by summarizing the survey responses provided by NWS forecasters in the region. The responses were summarized in a recent blog post by Jonathan that can be found here. Forecasters who have not submitted their comments to Bryce are encouraged to do so in the near future. The call participants agreed that developing a summary of the methods/results of the new interpolation method would be a good step. Bryce will develop a draft of this summary that the collaborators will review before submitting to the Tropical Wind Team for review on potential changes/additions to the TCMWindTool.

Bryce also showed the results of his first WRF-LES simulation. A very strong wind maximum develops in the WRF-LES domain after only a few hours of model simulation. After discussing with Dr. Sukanta Basu at NCSU, it was suggested that potential sources of this were the two-way nesting strategy implemented in the domains as well as the inclusion within the domain both continental and maritime environments. Future WRF-LES runs will attempt to test this hypothesis.

Participants of the call indicated the new test tools for gust and land reduction factors have been installed at the various WFOs and are ready for a case study this Atlantic TC season to evaluate the tools.

The next conference call will be held on Wednesday, August 14th at 11 AM.
