Modeling and Understanding the Meteorological Causes of the Southern California Ozone Episode of August 1997

Bob Bornstein, San Jose State University, and Jim Wilkinson, Alpine Geophysics

Research Project


The primary ozone episode monitored during the Southern California Ozone Study of 1997 occurred in early August. The investigators find that the meteorological causes of the August 1997 ozone episode involved important interactions between synoptic and mesoscale dynamics. The presentation will focus on the analysis of the interactions between synoptic and mesoscale meteorological influences, changes to the meteorological model MM5 that were required to correctly simulate those interactions, and statistical-graphical techniques used in the evaluation process.

Speaker Biography

Bob Bornstein has been a Professor in the Department of Meteorology at SJSU since 1969. His research has focused on observation, analysis, and simulation of polluted coastal urban boundary layers. His current efforts involve air quality studies in Israel, Houston, San Francisco Bay Area, and New York City.

Jim Wilkinson is currently a Ph.D. candidate in Engineering and Public Policy at Carnegie Mellon University and a Ph.D. candidate in Environmental Engineering at Georgia Institute of Technology. His recent research has focused on estimating the uncertainties in biogenic emissions and their impacts on predicted ozone formation, on developing a technique to apportion emissions source culpability to predicted air quality, and on developing statistical techniques to ascertain air quality and meteorological model performance.
