Datatake Envisat MERIS Wavelength 864.8 nm Bandwidth 19.999 nm September 16, 2004 at 17:14 West Indian Ocean Mozambique coast Comment The image reveals an atmospheric internal solitary wave packet propagating southwest off Mozambique's 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, and cloud bands of significant lateral extension, which indicate favourable condensation conditions in the ascending branches of the wave. Another small-scale internal wave may be seen propagating to the east southeast. Image |
