The latest image of sea surface heights in the Pacific Ocean from NASA's Jason-2 satellite shows that the equatorial Pacific Ocean is now in its 10th month of being locked in what some call a neutral, or 'La Nada' state.
The latest image of Pacific Ocean sea surface heights from the NASA's OSTIM/Jason-2 oceanography satellite, on June 11, 2010, shows that Pacific has switched from warm (red) to cold (blue) during the last few months.
This image from NASA's European Ocean Surface Topography Mission/Jason-2 shows that the moderate El Niño of the past year has officially bowed out, leaving his cool sibling, La Niña, poised to potentially take the equatorial stage.
Recent sea-level height data from NASA's Jason-2 oceanography satellite show a weakening of trade winds in western and central equatorial Pacific during late-January through February has triggered yet another strong, eastward-moving Kelvin wave.
El Niño Surges; Warm Kelvin Wave Headed for South America
The most recent sea-level height data from the NASA/European Ocean Surface Topography Mission/Jason-2 oceanography satellite show the continued eastward progression of a strong wave of warm water, known as a Kelvin wave, now approaching South America.
Pools of warm water known as Kelvin waves can be seen traveling eastward along the equator (black line) in this image from the NASA/French Space Agency Ocean Surface Topography Mission/Jason-2 satellite.
