Abstract
Mesospheric frontal-type gravity waves are an uncommon type of wave disturbance that occurs in the mesospheric OH, Na, O2, and O(1S) nightglow. They are understood to be the result of gravity waves exhibiting various degrees of non-linear behavior. Despite their similar appearance in all-sky images, careful analysis reveals that there are at least two distinct types of frontal wave disturbances, each with completely different consequences in terms of vertical momentum transport and deposition. Therefore, a correct identification is important in order to characterize their propagation modes. In this report we present the frontal gravity wave activity that occurred during a twelve-month period at Millstone Hill (42.6°N, 172.5°W), a mid-latitude site, to illustrate their range of behaviors.
