2013 Workshop: Planetary Waves and Tides

This workshop will focus on observations as well as modeling, assimilation and theoretical studies that deal with excitation, propagation and interactions of planetary waves and tides and their effects on both the neutral atmosphere and the ionosphere. As highlighted in CEDAR thrusts, traditional data comparisons with models are inefficient in determining what mechanisms and forcing’s can drive the model state towards observations. The aim of this workshop is to understand mechanisms of wave generation, wave-wave and wave-mean flow interactions, ionospheric dynamo coupling processes, year-to-year, annual and day-to-day variability in wave dynamics, and their impacts on neutral / ion composition. We welcome studies highlighting the seasonality of different planetary-scale waves and tides in the middle atmosphere and ionosphere from both observations and models. During this workshop we will assess capability of models to predict variability of tides and PWs and discuss data analysis/assimilation techniques needed for effective fusion of current and planned observations into the first-principle physics-chemistry based models to improve predictions of global waves. An additional objective is to facilitate dialogue between the middle atmosphere and ionospheric community on planetary wave and tidal processes of interest, and how efforts between the two communities can be coordinated.
