The latest data visualizations of conditions in the tropical Pacific Ocean show that moderate to weak La Nina conditions are present and expected to continue for months to come. Presently, cooler than normal sea surface and subsurface water temperatures extend more than 6000 miles across the equatorial Pacific Ocean.
Red colors indicate regions warmer than normal and blue regions indicate regions cooler than normal.
The evolution of La Nina can be seen as a blue region along the equator. Presently, cooler than normal sea surface and subsurface water temperatures extend more than 6000 miles across the equatorial Pacific Ocean. Red colors indicate warmer than normal conditions associated with El Nino and Blue colors indicate cooler than normal temperatures associated the of La Nina. The 1982-83 El Nino eventually reversed and developed into a La Nina pattern towards the end of 1983. El Nino and La Nina events.
