Air Quality Forecast and Weather Discussion
Sunday, sunshine and hot temperatures will increase ozone formation. Furthermore, light onshore winds will inhibit pollutant dispersion. As a result, ozone levels will be Moderate. Monday and Tuesday, an upper-level trough of low pressure moving over California will enhance mixing in the atmosphere and generate stronger onshore winds. These winds will enhance pollutant dispersion and bring slightly cooler tempeartures to the region, inhibiting ozone formation. Therefore, ozone levels will be low-Moderate on Monday and Good on Tuesday.
