    The Devil's in the Details

    Low and wispy clouds have escaped climate model detection until now. A new modeling system captures their most difficult-to-picture side: turbulence. Researchers from Pacific Northwest National Laboratory led implementation of a new system to represent turbulence in a multi-scale atmosphere model that improves the simulated distribution of low clouds.

    Remote Heat Rouses Hurricanes

    Scientists at PNNL identified a connection between the variations in temperature of the sea surface in the North Atlantic Ocean and the Mediterranean Sea and variations in Atlantic tropical cyclones from year to year. Their research is the first to use 30 years of observations to systematically identify the physical and statistical linkages between the two.

    Leung Invited to Guide Climate Modeling Directions

    Dr. L. Ruby Leung, PNNL Fellow and atmospheric scientist, was selected for positions on the National Center for Atmospheric Research (NCAR) Mesoscale and Microscale Meteorology Laboratory advisory panel and the Steering Committee of the World Climate Research Programme's High Resolution Model Intercomparison Project, the HighResMIP.

    Unlocking Cloud Gridlock

    Even as computing power increases, current climate model formulas struggle to handle storm clouds at today's higher resolutions and smaller model grid sizes. Cumulus storm cloud systems are still only partially resolved. Armed with a new formula developed by a PNNL-led research team, the approach breaks the storm cloud modeling gridlock by more accurately depicting how cumulus clouds transport moisture through the atmosphere.

    Ruby Leung Named to AGU Fellows Selection Committee

    Dr. L. Ruby Leung, Laboratory Fellow and atmospheric scientist at PNNL, was invited to serve on the American Geophysical Union's Fellows Selection Committee for the Atmospheric Sciences. An AGU Fellow since 2013, Leung joins nine other AGU Fellows for a two-year term on the committee. AGU is a professional scientific organization representing more than 62,000 members advancing the Earth and space sciences.

How do human activities and natural systems interact to affect the Earth's climate? Ultimately, that is the question challenging scientists in PNNL’s Atmospheric Sciences & Global Change Division.
