Short summary

This work explores the dynamics of the momentum and energy of propagating mesospheric gravity waves (GWs). A photometer was used to observe the vertical component of the GWs, whereas the horizontal component was observed by an all-sky imager. Using the parameters from these two instruments and background wind from meteor radar, the momentum flux and potential energy of the GWs were determined and studied. It is noted that the dynamics of the downward-propagating GWs were controlled by observed ducts.
