Short summary
Convection is an important source of atmospheric gravity waves (GWs). In this work, scales of convective GWs seen by limb sounders were first defined based on observed spectral information. Interactions of these waves with the background were considered. Long-scale convective GWs addressed by this approach showed significant importance in driving the QBO. Zonal mean of GW momentum flux and its vertical gradients are in good agreement with respective observations provided by limb sounders.
