The U.S. Department of Energy’s Atmospheric System Research program advances process-level understanding of the key interactions among aerosols, clouds, precipitation, radiation, dynamics, and thermodynamics, with the ultimate goal of reducing the uncertainty in global and regional climate simulations and projections.

Research Highlights

Turbulence and density currents below heavily precipitating marine stratocumulus clouds.

Downdrafts associated with heavy drizzle in stratocumulus clouds can bring colder air within the [...] Read more
