WebBoth atmospheric and oceanic equatorial Kelvin waves play an important role in the dynamics of El Nino-Southern Oscillation, by transmitting changes in conditions in the Western Pacific to the Eastern Pacific. There have been studies that connect equatorial Kelvin waves to coastal Kelvin waves. WebThey are so large and massive that they can change Earth's climate conditions. Along with rising sea levels, King Tides, and the effects of El Niño, oceanic Rossby waves contribute …
WebSome of it is also due to the heat stored in the water, so measuring the height of the sea surface is a good proxy for measuring the heat content of the water. Water expands as it warms, causing the surface of the ocean …
