3D simulation of 2018 sudden stratospheric warming and polar vortex
Researchers have simulated the 3D global morphology of atmospheric gravity waves from the surface to an altitude of about 100 kilometers of the 2018 sudden stratospheric warming event. The three-dimensional visualization revealed their shapes around the dramatically evolving polar vortex in February 2018, when the stratospheric polar vortex split into two sub-vortices. Paths of gravity waves near the Canadian sub-vortex were estimated, highlighting long-distance gravity wave propagation.
Atmospheric gravity waves have three-dimensional structures and propagate three-dimensionally from their sources. Examples include flow over mountains, convection, fronts, and imbalanced flow systems.
