With coastal areas bracing for rising sea levels, new research indicates that cutting emissions of certain pollutants can greatly slow down sea level rise. Reductions in the four pollutants that cycle comparatively quickly through the atmosphere could forestall the rate of sea level rise by roughly 25 to 50 percent.
Applying its atmospheric expertise to solar energy, NCAR is spearheading a three-year, nationwide project to create unprecedented, 36-hour forecasts of incoming energy from the Sun. The prototype system will forecast sunlight every 15 minutes over specific solar facilities, thereby enabling utilities to continuously anticipate the amount of available solar energy.
Even if you live more than 1,000 miles from the nearest large city, it could be affecting your weather. New research shows that the heat generated by everyday activities in metropolitan areas influences major atmospheric systems, raising and lowering temperatures over thousands of miles.
Raising further concerns about sea level rise, a study finds that the West Antarctica Ice Sheet is warming nearly twice as much as previously thought. The study, which will appear in Nature Geoscience, finds an increase of 4.3 degrees Fahrenheit since 1958 – three times faster than the global average.
NCAR has developed a prototype system to help flights avoid major storms as they travel over remote ocean regions. The 8-hour forecasts of potentially dangerous atmospheric conditions are designed for pilots, air traffic controllers, and others involved in flights over remote ocean regions where limited weather information is available.
Scientists have developed a new system that adapts techniques used in weather prediction to generate local forecasts of seasonal influenza outbreaks. By predicting the timing and severity of the outbreaks as far as seven weeks in advance, the system can eventually help society better prepare for them.
Climate model projections showing a greater rise in global temperature are likely to prove more accurate than those showing a lesser rise, according to a new analysis by NCAR. The findings could provide a breakthrough in the longstanding quest to narrow the range of expected global warming.
Expanding its focus on the link between the atmosphere and human health, NCAR is launching a three-year, international study into the impact of open-fire cooking on regional air quality and disease. The broad research team will analyze the effects of smoke from traditional cooking on households, villages, and entire regions.
The NCAR-Wyoming Supercomputing Center, which houses one of the world’s most powerful supercomputers dedicated to the geosciences, officially opens today. Scientists at NCAR and universities across the country are launching a series of initial scientific projects on the center’s flagship, a 1.5-petaflop IBM supercomputer known as Yellowstone.
With the U.S. economy vulnerable to weather events costing billions of dollars, an expert panel today asked Congress to create the first U.S. Weather Commission. The commission would provide guidance to policymakers on leveraging weather expertise across government and the private sector to better protect lives and businesses.
For airline passengers who dread bumpy rides to mountainous destinations, help is on the way. A new NCAR turbulence avoidance system has for the first time been approved for use at a U.S. airport and can be adapted for additional airports in rugged settings across the United States and overseas.
China's efforts to reduce pollution for the Beijing Olympics has enabled scientists to quantify traffic impacts on carbon dioxide emissions. New research led by NCAR shows Beijing's lighter traffic achieved a percentage of the emissions cut that would be needed worldwide to prevent warming from exceeding 2 degrees Celsius.
A decline in the population of emperor penguins appears likely this century as climate change reduces Antarctic sea ice, according to a detailed projection published this week. The study concludes that the number of breeding pairs in a much-observed penguin colony may drop by about 80 percent by 2100.
Scientists are targeting thunderstorms across the U.S. to discover what happens when clouds suck up air from Earth’s surface many miles into the atmosphere.
Scientists are working to solve a critical wintertime weather mystery: how to accurately measure the amount of snow on the ground.
A new international study, with NCAR co-authors, suggests that the Little Ice Age was triggered by an unusual, 50-year episode of four massive volcanic eruptions. This led to an expansion of sea ice and a related weakening of Atlantic currents that caused the cool period to persist for centuries.
Improved forecasting of winter storms and innovative technological systems to keep winter drivers safe are among the goals of new work at NCAR and collaborating organizations. The winter research, perfect for seasonal features, focuses on storm forecasting, stratospheric events that jeopardize communications systems, high-tech tools to measure snowfall, and more.
NCAR today announced that IBM will install major components of a petascale supercomputing system at the new NCAR-Wyoming Supercomputing Center. The system, known as Yellowstone, will advance the nation’s research capabilities for severe weather, climate change, and other critical areas of the geosciences.

The University Corporation for Atmospheric Research named Dr. Thomas J. Bogdan as its new president today, following an extensive international search. Bogdan, director of NOAA’s Space Weather Prediction Center, will assume his new position on January 9.
