Message: storm motion computation corrected

Posted by Geoff Manikin on 26 Jun 01, 8:38 MT

The algorithm that computes the storm motion vector in the operational RUC at NCEP has been changed to correct an error. The coding bug was leading to forecast values of helicity that were far too high for certain events. This correction was implemented at 12Z on 26 June 2001.
