Abstract
During August 29 through September 2, 2000, high surface ozone levels were observed over Houston, Texas. Observational and MM5 model data were used to evaluate the land/sea breeze event that occurred each day. The model did well in accurately representing the wind field in the lowest 4 km. Results show that changes in the large-scale wind pattern, as seen at 850 mb, can explain differences in the sea breeze circulation. Onshore flow leads to a faster moving sea breeze front whereas light opposing flow at 850-mb leads to a slower, stronger circulation. The varying sea breeze characteristics account for differences in the ozone distribution. Highest overall levels occurred on August 30 and 31: days with both a strong land breeze and nicely developed sea breeze when 850-mb winds were lightest. As clouds increased and afternoon showers developed on September 1, overall ozone measurements were lower.
