SA06. Connections Between the Lower and Upper Atmosphere and Ionosphere
Abstract submission site opened on 21 July 2010.
Deadline for submission is 2 September 2010.
Ample observational evidence has recently emerged revealing close connections between dynamical processes in the lower atmosphere and temporal and spatial variability in the thermosphere and ionosphere. Examples include observations of persistent four- or three-peak longitudinal structures in electric fields and plasma and neutral densities, or drastic changes in the equatorial ionospheric anomaly correlated with sudden stratospheric warmings. While mechanisms of such connections are still under investigation, global planetary and tidal waves, smaller-scale gravity waves, and their nonlinear interactions appear to play a prominent role. Correlative data analysis and modeling studies are solicited. Contributions offering insights into physical mechanisms of the teleconnections
terrestrial and space weather are of particular interest.
