California’s ongoing extreme drought must be a lesson for managing water in a warmer, more densely populated world, says a team of NOAA and University of California climatologists and hydrologists in an essay this week in Nature.
With the August 22 arrival of the NASA Global Hawk unmanned aircraft on Virginia’s eastern shore, scientists and pilots are now ready to start the NOAA-led mission to improve hurricane forecasts of track and intensity using data collected by the Global Hawk during the season’s hurricanes.
New research appearing online today in the journal Nature Climate Change by NOAA and partners forecasts the effects of climate change on countries' economic output and suggests that rising greenhouse gases may contribute to more extreme El Niños, the climate phenomenon that can trigger severe weather.
The hot and dry Santa Ana winds are associated with many of Southern California’s destructive wildfires, and even take the blame for tense, ugly moods. Now, NOAA researchers have found that on occasion the winds have an accomplice in contributing to California’s wildfires: atmospheric events known as stratospheric intrusions, which bring extremely dry air from the upper atmosphere down to the surface.
This hurricane season, NOAA’s Office of Oceanic and Atmospheric Research will work with NOAA’s National Weather Service to upgrade weather forecast models and conduct research with unmanned air and water craft to improve forecasts of hurricane track and intensity.
This summer, more than 20 NOAA scientists will stay up late to learn why some thunderstorms form and grow at night, without the energy from the sun's heat. They will be participating in the Plains Elevated Convection At Night (PECAN), a large, intensive field campaign to collect data before and during nighttime thunderstorms in the western Great Plains from June 1 to July 15.
It is too soon to know if recent extreme cold weather such as the last two East Coast winters are linked to Arctic climate warming, according to new research published in the Journal of Climate by James Overland of NOAA, and other authors from North America, Asia and Europe.
If you’ve ever sailed aboard a ship in the ocean, or checked a weather report before heading to the beach, then you are one of many millions of people who benefit from ocean observations. NOAA collects ocean observations and weather data to provide mariners with accurate forecasts of seas, coastal weather forecasts and regional climate predictions. Partnerships are essential to maintaining a network of free-floating, data-gathering buoys known as drifters. NOAA’s latest partner is not your typical research or ocean transportation vessel: the six sailboats and crew currently racing around the world in the Volvo Ocean Race.
Yes, there are rivers in the sky! Atmospheric rivers, to be exact, are narrow bands of moisture that regularly form above the Pacific Ocean and flow towards North America’s west coast, drenching it in rain and packing it with snow. These rivers, which transport more water than the Amazon or the Mississippi, have a far-reaching impact - even on the food you may be eating today.
With this week’s January 14 sailing of NOAA’s largest ship, the Ronald H. Brown, a major investigation of atmospheric rivers named CalWater 2015 is now underway.
