Research Areas
The Department of Meteorology continues its commitment toward maintaining active research
programs in the atmospheric sciences. Meteorology faculty are currently involved in
various projects supported by national agencies including NASA, the National Science
Foundation and the National Oceanographic and Atmospheric Administration. In most
cases, both undergraduate and graduate students are actively involved in these research
programs and work closely with faculty and staff. Present projects are directed at
both local and global issues using models and though analysis of observations. Brief
descriptions of current projects are given below (listed alphabetically).
Air Pollution/Urban Meteorology
Observation, simulation, and numerical modeling of polluted coastal urban boundary
layers. Specific interests include the alteration of weather and climate elements
in cities due to urbanization and air pollution and the effects of the new urban climate
on the spread of pollutants through the urban environment. Profs. Clements, Bornstein, & Chiao
Climate Change – Atmospheric Dynamics
Theoretical and numerical analysis of global and regional climate change as a result
of both natural and anthropogenic factors. This work involves understanding how atmospheric
variability affects and interacts with climate, and through simulations and analysis
of global climate models. Profs. Cordero, Bridger
Fire Weather and Wildfire Dynamics
Observations and simulations of conditions leading to severe fire weather in California.
Field measurement campaigns, including the use of UAVs (Unmanned Aerial Vehicles),
are focused on making on site observations of fire-induced winds, fire front propagation,
fire-plume temperature and moisture perturbations, and resulting convection. Measurements
and modeling of smoke emissions including PM2.5, Black Carbon and greenhouse gases
and their impacts on local air quality and climate. Profs. Clements, Chiao
Martian Weather
Studies of weather and climate on Mars using a state-of-the art computer model developed
at NASA's Ames Research Center. We compare the simulated atmosphere with the real
thing using new data coming in from missions such as Mars Global Surveyor. We use
models to simulate and understand the development of global dust storms on present-day
Mars. Prof. Bridger
Mesoscale Processes
Emphasis on mesoscale waves dynamics, orographic precipitation and clouds, downslope
winds, and drainage flows. Profs. Clements, Chiao
Mountain Meteorology
Observational and modeling studies of boundary layer evolution in mountainous terrain.
Specific topics include the development and dissipation of cold air pools and the
evolution of valley and slope circulation systems. Ongoing research is focused on
field studies conducted in Yosemite National Park to determine the role of valley
winds on the transport of ozone and other pollutants from California's Central Valley
to high-altitude regions in the Sierra Nevada. Profs. Clements, Chiao
Regional Wind Modeling
Analysis of local and regional wind patterns typical of northern California using
computer models. This involves understanding the roles played by the ocean, and the
coastal mountain ranges in generating observed winds. For more information please
see: SAN FRANCISCO BAY WIND PATTERNS.
Stratus Forecasting
Forecasting the time of stratus burnoff at San Francisco International Airport. For
more information please see: SFO Marine Stratus Forecast Guidance and SFO Marine Stratus Forecast Guidance Web Display.
Tropical Meteorology
Observational and modeling studies of hurricane rapid intensification processes;
Studies of tropical cyclogenesis and Saharan dust effects in Atlantic region. Prof. Chiao
Weather Systems and Forecasting
Research topics include synoptic, mesoscale, and convective weather systems via numerical
modeling, analysis of observations, and theory. Profs. Bridger, Chiao
Wind Energy Assessment
Observations and analysis of mesoscale wind patterns for the assessment of wind energy
potential at specific sites in California and the western US.This research includes
the deployment of towers and the departments Doppler SODAR system at remote locations
for site-specific wind studies. Prof. Clements
