Title: Gravity wave impacts on circulation and transport: Insights from high-resolution modeling studies

Presenter: Laura Holt, NorthWest Research Associates

Abstract: The representation of small-scale gravity wave drag is a primary factor controlling model biases in stratospheric winds and temperatures. Current methods for controlling these biases involve tuning of gravity wave drag parameterizations and time-consuming model iterations and diagnostics whenever changes are made to the model system. Ideally we would like to observe the wave drag to constrain models, but unfortunately observations can only provide us with a subset of waves at limited locations in space and time. One promising way forward is the utilization of high-resolution models to augment our limited observations and provide guidance for gravity wave parameterizations. In this talk I will describe some recent progress from studies that use validated high-resolution model experiments to examine small-scale waves, their sources, and how they interact with the large-scale circulation and transport.
