After an intense start to 2015, the waters of the South Pacific are finally cooling off, bringing relief to corals. But NOAA scientists expect stressful conditions to spread into the northeast Pacific and the Caribbean this summer.
Rainfall totals across parts of Texas and Oklahoma were several hundred percent above normal in May 2015, leading to record-breaking flood levels on many rivers.
How much warmer or colder than average would sea surface temperatures be in the eastern tropical Pacific Ocean in April 2015? That's the question we asked participants to answer in our new online game, in which players pit their predictive powers against experts’ opinions. The answer is in...
A new analysis suggests that in the winter following a La Niña, dryness in California often deepens into drought. Consistent with that pattern, California’s current drought began in 2011-12, during the second year of a La Niña episode.
Uncommon atmospheric circumstances spawned a pair of tropical cyclones in the western Pacific—one on either side the equator, at nearly the same longitude, at nearly the same time. Why are twin cyclones more common during El Niño?
This pair of maps shows whether your state tends to have wet, dry, or average springs during El Niño, and how often the wet or dry pattern occurred during the last 10 El Niño years.
