Oceanic Rossby wave (Rev #2, changes)

Showing changes from revision #1 to #2: Added | Removed | Changed



Oceanic Rossby waves are very low-frequency waves in the ocean’s surface and thermocline. At the ocean’s surface they are only 5 centimeters high, but hundreds of kilometers across. They move at about 10 centimeters/second, requiring months to years to cross the ocean! The surface waves are mirrored by waves in the thermocline, which are much larger, 10-50 meters in height. When the surface goes up, the thermocline goes down.


You can watch a 3-year long movie of oceanic Rossby waves, and also read more about them here:

These authors have investigated the characteristics of low-frequency, large-scale Rossby waves using data from the TOPEX/Poseidon satellite.
