Response of MCSs and low-frequency gravity waves to vertical wind shear and nocturnal thermodynamic environments
Low-frequency gravity waves have been found to both increase and decrease environmental favorability ahead of mesoscale convective systems (MCSs) based on their associated vertical motions. The strength and timing of these waves is determined by the internal dynamics of the MCS. This study investigates the sensitivities of MCSs to changes in the vertical wind and thermodynamic profiles through idealized cloud model simulations, highlighting how internal MCS processes impact low-frequency gravity wave generation, propagation and environmental influence. A common feature among all of the simulations ...
