Gravity Waves at Low-Mid Latitudes from NRCM

Global distribution of atmospheric gravity waves is key to the understanding of middle and upper atmosphere dynamics. In a recent study, we examined the gravity waves from the Nested Regional Climate Model (NRCM). These animations show the vertical wind fields at 20 km with zonal wavelength between 100-200 km, 200-400 km, 400-800 km, and 800-1600 km from NRCM simulation of 1-8 January, 2005.
