The session addresses three foci: (1) the session is on understanding coupling mechanisms due to atmospheric waves (planetary and gravity waves as well as infrasound) in the middle atmosphere based on satellite and non-satellite measurements. Of special interest are non-linear effects such as non-linear resonant wave-wave interactions. But also results concerning wave sources, wave breaking, reflection and ducting are welcome. (2) Quantifying and understanding trends in wave patterns in the middle atmosphere and especially in the mesopause region are adressed. (3) Contributions dealing with the impact of atmospheric dynamics on validation are invited. Addressed are aspects like miss-time, miss-distance and miss-integration errors.
