Abstract : In this report we investigate: (1) alternative and more direct means of observing gravity waves using optical methods as well as the effects of winds on gravity wave propagation; (2) the effects of gravity wave critical layer interactions, and their effects on the nonlinear response of minor species; (3) the guidance of long and short period gravity waves and their implications on some ALOHA data, in particular, the by now well known and rather unusual 'Wall' event. All three investigations are carried out in collaboration with other members of the SOAR program who provide much of the data on which the theoretical analyses are based.
