Observing & Predicting
Department:December 14, 2016A black swan event is a situation so rare that few people would have imagined it was possible. In November 2016, researchers were caught off guard by just such an event: extremely low sea ice extents in both the Arctic and Antarctic.
Department:December 13, 2016A new NOAA-sponsored report shows that unprecedented warming air temperature in 2016 triggered massive declines in sea ice and snow cover across the Arctic, and brought a record-breaking delay to fall sea ice freeze up. Learn more through our image highlights of the 2016 Arctic Report Card.
Department:December 1, 2016Providing more timely and accurate information over the western hemisphere, total lightning mapping, and higher resolution images streaming down from space more often, the new GOES satellite marks the first major redesign of the nation’s operational Earth-observing technology in more than 20 years.
Department:November 30, 2016While the U.S. was observing Thanksgiving last week, Costa Rica was facing the first landfalling hurricane on record for the Central American country.
Department:November 23, 2016Are sea surface temperatures located north of the equator important for El Niño or La Niña development? Yes! Introducing the Pacific Meridional Mode.
Department:November 15, 2016Multi-year drought in California has been joined this summer and fall by extreme and exceptional drought across the Southeast and moderate to severe drought in parts of New England.
Department:November 2, 2016A broad expanse of 80+ degree water dominated the tropical Pacific last winter. This animation shows how these warm surface waters were eroded by waves of cool water that pulsed across the equator throughout spring and summer.
Department:October 26, 2016Using a combination of observations and models, NOAA-funded scientists have found a small but significant “advanced warning” signal for heightened summer tornado activity in the U.S.: warmer-than-average water temperatures in the Gulf of Mexico
Department:October 25, 2016What are NOAA's predictions for this possible La Niña winter of 2016-17, and how did its predictions for last winter fare during the strong El Niño? Guest blogger Mike Halpert gives us the lowdown.
Department:October 19, 2016Unlike the United States' extreme temperature places, which are dominated by where you sit on a map, the extreme precipitation places tend to be dominated by what features are near you. We'll explore the driest and wettest places in the United States.
