These images show that the central and eastern Pacific Ocean was unusually cold in December 2010, a tell-tale sign of La Niña. The associated rainfall map shows that La Niña was impacting weather in parts of the globe.

Astronauts aboard the Space Shuttle Discovery used the sunglint off the surface of the Mediterranean Sea to reveal biogenic films on the ocean surface (“Biogenic film” refers to a thin layer of biologically-produced film resting on the surface.). The films dampen surface capillary waves, creating brighter and darker reflections, which, in turn, trace the complex surface water movements along the coast. The sunglint also highlights coastal features (jetties, submerged costal areas) near the Port of Suez.

La Niña is an occurrence of unusually cold water temperatures in the Pacific Ocean along the equator (the precise area affected is outlined in black in the image above). La Niña and its opposite, El Niño, are linked to seesaw variations in air pressure over the tropical Pacific and affect weather patterns across the globe. NASA monitors developing El Ni&ntidle;o and La Niña events by observing sea surface temperatures. This image compares the water temperatures observed in late January 2006 to long-term average conditions for that time of year. The recent data were collected by the Advanced Microwave Scanning Radiometer for EOS (AMSR-E). Red shows where sea surface temperatures are warmer than normal and blue where they are colder than normal.
