%X Using airglow imagers, a particular type of gravity wave event called a mesospheric bore was observed over Germany and the observation was complemented by 2D Direct Numerical Simulation of the Navier-Stokes equations under Boussinesq approximation. The inclusion of the wind in addition to temperature, led to the generation of secondary instabilities previously reported in observations of both bores and solitons. The extension of the existing simulation to 3D showed that the dynamics are also influenced by the generation of these instabilities in the transverse direction to the propagation.<eng>
