  • warm climate conditions enhance subtropical high-pressure systems

    Warmer Climate Brings Stronger Spring Storms to U.S.

    Simulations show North Pacific and North Atlantic subtropical high-pressure systems are enhanced more during spring than summer under future warming, with great implications for regional precipitation patterns.

  • The roles of ocean and atmosphere in cyclic changes of sea surface temperature

    Disentangling the Ocean-Atmosphere Interactions in the North Atlantic

    This study shows that surface heat fluxes act to damp the variability of ocean-driven sea surface temperature. This implies that the strength of surface coupling in global climate models might be one of the reasons why many Earth system models simulate weaker Atlantic Multidecadal Variability compared to observations.

  • PNNL researchers develop more accurate model of volatile organic compounds

    New Aerosol Modeling Approach Takes Cues from Lab Experiments

    PNNL researchers are unraveling the complex evolution of secondary organic aerosols and their effect on climate. Studying isoprene in lab experiments, they developed a consistent way to represent dynamic SOA chemistry in three-dimensional chemical transport models.

  • Dr. Susannah Burrows

    Susannah Burrows Honored with Brodzinski Early Career Exceptional Achievement Award

    Dr. Susannah Burrows, an atmospheric scientist at Pacific Northwest National Laboratory, recently received a 2018 Ronald L. Brodzinski Early Career Exceptional Achievement Award. Burrows was recognized for her leadership in improving the understanding of connections between biological systems on land and ocean and their chemistry, and physical climate processes in the atmosphere. The Brodzinski award is named after a former PNNL Laboratory Fellow and nuclear physicist to honor his passion for mentoring early career staff.

  • building energy codes reduce greenhouse gas emissions

    Linking Local and National Government for Global Mitigation

    Less-developed countries may lack what is needed to implement their energy efficiency goals. Pacific Northwest National Laboratory and the University of Maryland performed case studies in six cites on different continents to identify barriers to building energy code implementation and assess how they can be mitigated.

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.
