Turbulence in Extreme Weather Events

Session ID#: 74801

Session Description:
The range of spatial and temporal scales controlling the dynamics of geophysical fluid flows are vast and span several orders of magnitude from large-scale Rossby waves in the atmosphere to small-scale eddies responsible for viscous dissipation in the atmosphere and ocean.  This wide range of scales, and particularly the nonlinear interactions between them, pose significant difficulties for observational systems and numerical simulations that limit our understanding and predictive capability of extreme weather events.  The frequency of extreme weather events (e.g. hurricanes, winter storms, cold air outbreaks, fires) appears to be increasing in the current climate and it is important to assess the current state of knowledge and performance of predictive models for these disruptive events. This session invites scientists and engineers studying turbulence in extreme weather events on a wide range of spatial/temporal scales using all available tools (theory, modeling and observations).
