Images of structure in the OH nightglow emission have been used to establish the presence of short period gravity waves in the winter polar mesosphere. The observations, which were made from the auroral station at Longyearbyen, Svalbard (78°N), are currently being used to investigate the generation of small scale gravity waves by auroral processes. Results so far show that the airglow wave patterns appear similar in both morphology and dynamics to those commonly seen at mid-latitudes indicating tropospheric sources for the waves. However, on one occasion there is good evidence for the generation of gravity waves by an auroral electric field that exhibited an intrinsic periodicity close to that observed in the airglow wave pattern Further studies are in hand.
