Comment
The image reveals an atmospheric internal solitary wave packet propagating west off Madagascar's southwest coastline. The large-scale internal solitary wave packet is made visible by characteristic sea surface roughness patterns, which are due to modulation of Bragg waves associated with wind stress variability on the sea surface.
