TIDES, PLANETARY WAVES, AND ATMOSPHERIC COUPLING

A growing number of studies report linkages between unrelated stratospheric and upper atmospheric phenomena. For example, stratospheric warmings correlate with ionospheric perturbations, and with reductions in polar mesospheric cloud occurrence. Understanding these so-called teleconnections is important for prediction of the near-space environment, and interpreting global change proxies. Tides and planetary waves are important agents for vertical and lateral coupling. This presentation will consist of a brief tutorial on tidal and planetary wave dynamics, and showcase their roles in transmitting tropospheric and stratospheric variability to high altitudes, and between hemispheres.
