Cyclone Gonu on NASA/MODIS satellite, 6/4/07
August 20, 2014
A case study indicates that the COSMIC microsatellite system can significantly improve predictions of tropical cyclones by using GPS radio occultation to observe remote regions of the atmosphere.
Sea surface temperatures during 2007–08 La Niña
August 13, 2014
For millions of people, El Niño or La Niña indicates whether they’re likely to face unusually warm, cold, wet, or dry conditions over the coming winter. A new modeling study pins down the process that apparently determines why La Niña events often last twice as long as typical El Niño events—a result with major implications for seasonal predictions.
Depiction of model-produced meridional circulation beneath solar surface
August 05, 2014
A leading goal of solar scientists is to improve predictions of the Sun's approximately 11-year cycle. New research led by scientists from NCAR and Sweden shows how solar predictions can borrow from weather forecasting techniques in order to predict the timing and extent of the solar cycle.

Scientists have found that internal variability can make one season twice as active as another, even when large-scale hurricane-shaping elements are unchanged. The research suggests that seasonal hurricane forecasts could be improved by conveying the amount of unavoidable uncertainty in the outlook.
Pollution, fires, warming west: A fire burns on Camp Pendleton, California
June 25, 2014
California will likely experience more large fires in forested areas this century because of rising temperatures and changes in precipitation along with development patterns, new research finds. The blazes could increase some types of fire-generated air pollution by more than half.

Geophysical Research Letters, a leading journal in Earth science, is toasting its 40th anniversary this month with an editor-picked retrospective collection of 40 papers, including several with authors from NCAR.
Water: too much, too little - Image shows effects of major drought on plants across U.S. on June 24, 2011
April 10, 2014
Climate change will reduce water availability during dry seasons and increase it during wet seasons around the globe, new research suggests. It also finds there will be large regional variations in water-related impacts.
March 12, 2014
Increased Pacific winds are sending excess heat into the deep ocean and likely playing a role in the current hiatus in global warming.
Arctic sea ice: Regional nuclear conflict could lead to extended global cooling
March 03, 2014
A nuclear exchange, even if limited to one region, would have severe atmospheric impacts.
Pollution above Asia: Layer in stratosphere may originate from global sources
February 19, 2014
Scientists link coal, oil, and biomass to a layer of sulfates high above Asia.
