Ground-based zenith photometric observations at São João do Cariri (7°S, 37°W), Brazil, reveal the existence of ∼25–40% quasi-3-day oscillations in OI(5577Å), O₂(0,1), and OH (6,2) emissions and upper mesospheric temperatures (∼6K) during June and July, 1998. A previous numerical model study [ Forbes, 2000 ] has reported on the global characteristics of a 3-day Kelvin wave with zonal wavenumber s = 1, and consistency with satellite and radar observations. Herein we present the results of a one-dimensional dynamical-chemical simulation that demonstrates that the photometric observations are consistent with a Kelvin wave interpretation. Thus, a connection is made for the first time between convective processes in the tropical troposphere, and upper atmospheric airglow emissions.
