Recent LIDAR research at USU found a noctilucent cloud (NLC) near the minimum of a large-amplitude temperature wave in the upper mesosphere. Such a large-amplitude wave had not been seen previously. Initial analysis suggested that this wave might be related to the diurnal tide, but greatly amplified. This research set out to learn whether these waves are a common feature. Large waves or temperature “bumps” exceeding 10 K were found in more than half the observations. A later stage will be to see if they are linked to the tides.
