Presenters: Matthew Fearon, Desert Research Institute and Robyn Heffernan, National Weather Service
Mixing Height is important for assessing smoke dispersion for prescribed fires and wildfires. This webinar will review and explain the strengths and weaknesses of several tested methods for determining mixing heights. The webinar will include discussion of the innovative Turbulent Kinetic Energy (TKE) method which examines several critical atmospheric variables for predicting Dispersion. TKE represents the most robust method for determining Mixing Height while the Stull Method represents an alternative approach that may be more operationally feasible. The webinar will discuss both approaches for determining Mixing Height. In addition, the National Weather Service will describe their work on a national standard for Mixing Height as a weather element in the NWS Fire Weather Program. Following the presentation there will be ample opportunities for Q/A and discussion
