---------------------------------------- Type of abstract: Invited for Student Workshop Presenter Name: Feng Li Status of first author: student_not_in_poster_competition PhD ---------------------------------------- Title: Observations of gravity waves in the mesopause region from an OH all-sky imager at Starfire Optical Range ---------------------------------------- Authors: Feng Li, University of Illinois, fengli@uiuc.edu ---------------------------------------- Abstract: A brief overview of the dynamical roles and the triggering mechanisms of the gravity waves is given as the first part of the talk. In the second part the observations of two-dimensional airglow structures by an OH all-sky imager at Starfire Optical Range are presented. Well-defined wave patterns are found, and they are interpreted as small-scale quasi-monochromatic gravity waves. ---------------------------------------- Mesosphere
