GENERATION OF MEDIUM SCALE TRAVELING IONOSPHERIC DISTURBANCES FROM TROPOSPHERIC WEATHER EVENTS
Abstract
Atmospheric gravity waves (AGW) in the neutral atmosphere generated by tropospheric weather events are an important mechanism for the transport of energy and momentum over many thousands of kilometers. If they propagate to ionospheric altitudes, they perturb the ionosphere and affect the performance of HF instruments such as wide area surveillance over-the-horizon (OTH) radar which utilize the ionosphere. This project involves the development of a novel and unique approach to understand the origin of the smaller scale ionospheric variations through the modelling of the propagation of AGWs generated by terrestrial weather events. We envisage the research outcomes from this work may allow us to ultimately be able to account for the smaller scale ionospheric variations and thereby improve the performance HF instruments which rely on the ionosphere.
