Atmospheric science is the study of the physics, chemistry, and dynamics of the atmosphere and its interrelationship with the hydrosphere and the biosphere. Students gain advanced knowledge of air quality, meteorology, atmospheric chemistry, micrometeorology, biometeorology, climate dynamics, mesoscale meteorology, large-scale dynamics, and numerical weather prediction. Students graduate with the qualitative and quantitative skills necessary for professional research and teaching in the chemistry and dynamics of the atmosphere and its interrelationship with the hydrosphere and the biosphere. The Graduate Group in Atmospheric Science offers both M.S. and Ph.D. degree programs. A student may place emphasis on graduate work in one or more of the following fields: air quality meteorology, atmospheric chemistry, cloud physical processes, biometeorology, micrometeorology, numerical weather prediction, remote sensing, climate dynamics, large-scale dynamics, meso-scale and boundary-layer meteorology, computational geosciences, extreme weather, and climate change impacts. The diverse and extensive backgrounds of the faculty allow opportunities for interdisciplinary training and research.
The Large-Scale and Climate Dynamics program at Davis examines basic fluid dynamics and short-term climatic processes. Some of the research combines dynamics, thermodynamics, radiation and synoptic meteorology. The phenomena studied range in scale from a single midlatitude frontal cyclone up to global circulations. Some students are investigating fluid dynamic instabilities with linear and nonlinear models of frontal systems. Large-scale tropical circulations and their midlatitude interactions are incorporated into this program, as well. Most students are using various computer models to simulate atmospheric circulations. Some students are also studying observational data with advanced statistical techniques.
