Repeating La Niña Hitting Its Peak: NASA
2012-01-21 04:27:40

La Niña, "the diva of drought," is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry. Sea surface height data from NASA's Jason-1 and -2 satellites show that the milder repeat of last year's strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean shown above. The image is based on the average of...

ESA´s CryoSat mission has been gathering detailed information on the thickness of Earth´s ice since its launch in 2010. Through international collaboration, this state-of-the-art mission is soon to be used to monitor conditions at sea for marine forecasting. CryoSat was built to measure tiny variations in the thickness of Earth´s ice. As a result, the mission is providing scientists with the data they need to help improve our understanding of the relationship between ice,...

Image 1 - Japanese Devastation The Result Of Merging Waves

[ Watch the Video ] Researchers from NASA and Ohio State University have discovered that the deadly tsunami generated from the March 2011 Tohoku-Oki earthquake that devastated northeastern Japan resulted from merging waves, causing the killer tsunami to double in intensity over ocean ridges, and then amplifying its power upon landfall. Data taken from NASA and European radar satellites captured at least two wave fronts during the events that day. The fronts merged to form a single, more...

WASHINGTON, Dec. 5, 2011 /PRNewswire-USNewswire/ -- NASA and Ohio State University researchers have discovered the major tsunami generated by the March 2011 Tohoku-Oki quake centered off northeastern Japan was a long-hypothesized "merging tsunami." The tsunami doubled in intensity over rugged ocean ridges, amplifying its destructive power at landfall.

  An Update from NASA's Sea Level Sentinels: Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming. While the rise of the global ocean has been remarkably steady for most of...

New NASA satellite data indicate the current La Niña event in the eastern Pacific has remained strong during November and December 2010. A new Ocean Surface Topography Mission (OSTM)/Jason-2 satellite image of the Pacific Ocean that averaged 10 days of data was just released from NASA. The image, centered on Dec. 26, 2010, was created at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. "The solid record of La Niña strength only goes back about...

The tropical Pacific Ocean has transitioned from last winter's El Niño conditions to a cool La Niña, as shown by new data about sea surface heights, collected by the U.S-French Ocean Surface Topography Mission (OSTM)/Jason-2 oceanography satellite. This OSTM/Jason-2 image of the Pacific Ocean is based on the average of 10 days of data centered on Sept. 3, 2010. A new image depicts places where the Pacific sea surface height is higher (warmer) than...

The latest image of Pacific Ocean sea surface heights from the NASA/European Ocean Surface Topography Mission/Jason-2 oceanography satellite, dated June 11, 2010, shows that the tropical Pacific has switched from warm (red) to cold (blue) during the last few months. The blue area in the center of the image depicts the recent appearance of cold water hugging the equator, which the satellite measures as a region of lower-than-normal sea level. Remnants of the El Niño warm...

Scientists and agencies monitoring the oil spill in the Gulf of Mexico are keeping a wary eye on changes in the nearby Loop Current, a warm ocean current that is part of the Gulf Stream. Beginning as a large flow of warm water from the Caribbean, the Loop Current heads up into the eastern part of the Gulf of Mexico and then turns south before finally moving out through the Straits of Florida and northward into the Gulf Stream. Deep and fast moving, the Loop Current often breaks off and forms...

In an effort to monitor the behavior of the world's oceans, Europe has committed to build the next Jason altimeter spacecraft -- a decision that should guarantee the continuation of a remarkable 18-year record of sea-surface shape until late in the decade, BBC News reported. The recent steady 3mm per year rise in global sea level has been tracked by the Jason series. The data has become invaluable to oceanographers, weather forecasters and climatologists. Eumetsat, which looks after Europe's...
