Abstract:

The main objective of this research was to understand the processes that dynamically couple the troposphere at equatorial tropical latitudes with the overlying thermosphere-ionosphere. and identify those aspects of ionospheric variability which may be directly attributable to these processes. Using a combination of data analyses and numerical simulations, a new understanding of the excitation mechanisms, propagation characteristics, and lower thermosphere perturbations relating to tropospherically-excited Kelvin waves and nonmigrating tides has been developed. In addition. an analyses of ionospheric data was completed that provides an estimate of the meteorological contributions to ionospheric space weather.
