TC Winds Group Conference Call Notes (10/10/12)

The CSTAR TC Winds Group held their monthly conference call on Wednesday, October 10, 12th.  The participants on the call were Bryce Tyner (NCSU), Reid Hawkins (ILM), Michael Brennan (NHC), Jonathan Blaes (RAH), and Bob Bright (CHS).  A summary of the call is highlighted below:

  • Bryce discussed the NDFD questionnaire.  As of the time of the call, only one survey had been returned completed.  Bryce will post on the blog to remind collaborators to participate in the survey.  Reid will also send out a reminder via email.  A deadline of Friday, November 2nd, 2012 was established in order to allow time for incorporation into the climatology paper to be submitted to Weather and Forecasting.
  • A summary of the Holland et al. (2010) verification was discussed by Bryce.  Bryce has shown success via reduced sensitivity to the TCM wind radii product as well as a smoother wind field and reduced winds when compared to the modified Rankine vortex interpolation method.  As a final step to the verification, Bryce has begun conducting a comparison to H*Wind analyses.  As a starting place, he conducted a verification of Irene (2011).  Results showed a lack of significant improvement using the Holland et al. (2010) model.  Bryce hypothesizes that this may be due to the dependency of the interpolated winds onto the central pressure for the storm.  Irene (2011) was an anomalous storm with very low central pressure compared to the maximum sustained winds.  Bryce will continue his analysis for recent storms since 2000 and will post on the blog as the images are available.
  • The November CIMMSE group meeting has been cancelled.  Stay tuned for the possibility of a CIMMSE group webinar in its place, which is currently being discussed.
  • The next conference call will be held Wednesday, November 10th at 11 a.m.
  • Slides from the call are available here: cc_2012_10
