Air Pollution/Urban Meteorology

Observation, simulation, and numerical modeling of urban heat island (UHI) and 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.


Global, regional climate modeling, natural role of trace gases, aerosols, and clouds in global climate, impacts of climate changes on air pollutant emissions and air quality, bias introduced by urban heat islands in assessing global warming, use of long-range transport models to investigate source regions, movements, and deposition patterns associated with pathogenic spore clouds, and synoptic climatology of weather events associated with tropical and extra-tropical cyclones.

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.

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.

Weather Systems and Forecasting

Research topics include synoptic, mesoscale, and convective weather systems via numerical modeling, analysis of observations, and theory.

Mesoscale Processes

Emphasis on mesoscale waves dynamics, orographic precipitation and clouds, downslope winds, and drainage flows.

Tropical Meteorology

Observational and modeling studies of hurricane rapid intensification processes; Studies of tropical cyclogenesis and Saharan dust effects in Atlantic region.

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.

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.
