NOAA flies through atmospheric rivers off California coast

Researchers study evolution and structure of moisture-bearing rivers in air

Scientists aboard the NOAA Gulfstream IV aircraft are flying over the Pacific Ocean off the U.S. West Coast this week to measure air pressure, temperature, humidity, wind speed and direction to help better understand atmospheric rivers - narrow conveyor belts of water vapor that can bring beneficial water supply and snowpack as well as create dangerous floods.

NOAA launches research on next generation of high performance weather, climate models

NOAA collaborates with U.S. Navy, other public and private partners to create faster, lower-cost models

NOAA and the U.S. Navy are teaming up with academic and other government scientists to design the next generation of powerful supercomputer models to predict weather, ocean conditions and regional climate change.

 

Four teams of scientists are beginning projects this month to rewrite computer models that will create faster, lower-cost, better integrated models.  These new models will take advantage of new supercomputers that use more energy efficient/lower-cost processors such as those originally developed for the video gaming industry.

NOAA research shows limits to detecting geo-engineered increases to sunlight reflection

A perspective from NOAA and NASA scientists published online on January 29, 2014 in Nature Climate Change addresses a key question surrounding proposals to engineer the Earth’s climate to increase the planet’s reflection of sunlight to counteract climate warming: Could we measure manmade increases in reflectivity?

New study: U.S. power plant emissions down

CIRES, NOAA scientists find switch to natural gas power plants means fewer air pollutants

Power plants that use natural gas and a new technology to squeeze more energy from the fuel release far less of the greenhouse gas carbon dioxide than coal-fired power plants do, according to a new analysis accepted for publication Jan. 8 in the journal Earth’s Future, a journal of the American Geophysical Union. The so-called “combined cycle” natural gas power plants also release significantly less nitrogen oxides and sulfur dioxide, which can worsen air quality.

Arctic melt season puts focus on sea ice forecasts Read more

Improving Arctic sea ice forecasts is a high priority for NOAA, as indigenous communities, fisheries, ecotourism, oil and gas industries, shipping concerns, wildlife managers and scientists need better information in a region that is rapidly shifting from a reliable frozen ice cap to an open-water ocean. Check out an animation of this summer's Arctic snow and ice melt.

The study evaluated all of the aviation industry’s contributing factors to climate change, including emissions of carbon dioxide and nitrogen oxide, and the effect of contrails and contrail cirrus – short-lived clouds created in jet engine exhaust plumes at aircraft cruise altitudes that reflect sunlight during the day and trap heat trying to escape at night.
