Research Abstract |
We analysed the vertical propagation of gravity waves from the lower to the upper atmosphere from combined measurements with an airglow imager and lidars/radars in the northern Europe. Ray-tracing analysis suggested that the gravity wave observed in the mesospheric airglow was generated by a distortion of the polar jet at the tropopause height, approximately 2600 km away from the airglow observation site. This result implies that gravity waves could affect atmospheric dynamics in the ionosphere in regions far away from their source. Based on this idea, we also developed an analysis environment for simultaneous airglow imaging network data from multipoint observations in Japan in order to investigate wave propagation structures with a spatial extent covering Japan. By using the network analysis, we showed, for the first time, "observational evidence for ducted gravity wave propagation over a very large distance" and "large concentric airglow structures induced by Typhoon Pongsona".
