Interacting "morning glories' over northern Australia

Abstract

It is just over 15 years since the first major expedition was organized to investigate the "morning glory' phenomenon of northeastern Australia. The authors present data for a particularly interesting event that occurred on 3 October 1991, a day on which two morning glory wave formations, one from the northeast and one from the south, were seen to interact over the Gulf of Carpentaria. Spectacular National Oceanic and Atmospheric Administration/Advanced Very High Resolution Radiometer satellite imagery are presented for this event. Aspects of the interaction between the northeasterly and southerly morning glories are shown to be consistent with theoretical predictions concerning solitary wave interactions. -from Authors
