  • Fanning the flames of megafires
    July 24, 2018 | Although drought and overgrown forests are often blamed for major fires in the western United States, new research indicates that various types of highly localized winds sometimes play a much larger role, creating large, destructive fires even when regional winds are weak.The study, led by the...

  • Double the data: Putting weather observations in the cloud increases access
    May 1, 2018 | Meteorologists and other users accessed more than twice as much U.S. weather radar data after the National Oceanic and Atmospheric Administration (NOAA) partnered with Amazon and the University Corporation for Atmospheric Research (UCAR) to make the data available in the cloud. The collaboration is part... Read more »
  • The entire atmosphere in a single model
    May 1, 2018 | As the atmosphere approaches the edge of space, it behaves very differently than it does closer to the surface, where weather takes place. For one thing, while the lower atmosphere warms in response to emissions of carbon dioxide (CO2), the outer and less dense atmosphere cools,... Read more »
  • Taking the temperature of streamflow forecasts
    February 21, 2018 | Adding temperature predictions into seasonal streamflow forecasts in the U.S. Southwest could increase the accuracy of those forecasts, according to a new study that analyzed historical conditions in the headwaters of the Colorado and Rio Grande rivers.Many rivers in the western United States are fed by...

  • The rate of sea level rise is accelerating, a new study finds
    NCAR scientist John Fasullo is a co-author of a new study appearing in the Proceedings of the National Academies of Science. The study finds that the rate of sea level rise is accelerating. The following is an excerpt from a news release by the Cooperative Institute for Research in Environmental... Read more »
  • Drier and wetter: The future of precipitation variability
    January 17, 2018 | Precipitation variability — the swing from dry to wet and back again — will continue to increase across the majority of the world's land area as the climate warms, according to a new study led by scientists at the National Center for Atmospheric Research.The researchers expect...

  • New model reveals origins of the Sun's seasons
    December 4, 2017 | The solar seasons — which change every six to 18 months from "bursty" to quiet, and vice versa — have been realistically simulated for the first time in a computer model of the Sun's shear layer beneath the turbulent outer shell, an advance that promises the... Read more »
  • New research could predict La Niña drought years in advance
    NCAR Senior Scientist Clara Deser is a co-author of two new studies, published this month in the journal Geophysical Research Letters, that examine the impacts and predictability of La Niña. The following excerpt is from a news release by the University of Texas at Austin, a UCAR Member.Nov. 16, 2017... Read more »
  • Investing in climate observations would generate major returns
    November 14, 2017 | A major new paper by more than two dozen climate experts concludes that a well-designed climate observing system could deliver trillions of dollars in benefits while providing decision makers with the information they need in coming decades to protect public health and the economy."We are on...

  • Climate change could decrease Sun's ability to disinfect lakes, coastal waters
    October 20, 2017 | One of the largely unanticipated impacts of a changing climate may be a decline in sunlight's ability to disinfect lakes, rivers, and coastal waters, possibly leading to an increase in waterborne pathogens and the diseases they can cause in humans and wildlife.A new study published in...
