Horizontal structure of the slowest westward-propagating inertia-gravity (WIG) mode on the sphere, n=0 WIG wave.
Geopotential height is scaled by the maximal height. Colours vary between -1 and +1 with positive/negative perturbations in red/blue.
Wind components are scaled by the maximal wind speed. The equivalent depth is 1536 meters.
