The Development of a Stratospheric Real-Time Turbulence Modeling System
Abstract
This research project focused on the development of an automated numerical prediction system for stratospheric turbulence. This involved modifying and testing a stratospheric mesoscale numerical model with observed initial data from several case studies. A sequence of events was simulated that likely organized environments favorable for stratospheric turbulence. This sequence involved the development of large amplitude hydrostatic gravity waves that in turn modified the lower stratospheric environment making it favorable for wave breaking and significant eddy dissipation. An automatic grid nesting location system was tested that exploited three different dynamical indices, which would be indicators of the potential for stratospheric turbulence i.e., the NCSU1 index, vertical variation of the Scorer parameter as well as the eddy dissipation rate derived from the complete turbulence kinetic energy equation. The automatic grid nesting scheme was utilized for several case studies wherein large amplitude gravity waves and substantial latent heating were simulated.
