Alternative Meteorological Criteria

April 17, 2002 Meeting


Notes from April 17, 2002 Meeting
9:00 a.m. - 11:00 a.m.


ARB meteorology staff and district staff from the North Central Coast Air Basin and San Luis Obispo County met in Monterey to discuss changes in meteorological criteria and zone implementation. Meteorological conditions are very different along the coast from those in the interior portion of the air basins. District representatives from the North Central Coast and San Luis Obispo County proposed dividing the regions into two zones: a coastal zone and an inland zone.
In the North Central Coast Air Basin the coastal zone burn criteria would be based on a maximum mixing height of 1,500 feet and wind speed equal to or greater than 5 mph but less than 15 mph. The inland zone burn criteria would require a maximum mixing height of 1,500 feet and wind speed equal to or greater than 5 mph.
San Luis Obispo County would prefer to see a maximum mixing height of 2,000 feet and wind speed equal to or greater than 5 mph in the coastal zone. Inland zone burn criteria would be based on 12z and 00z 500 mb heights, a maximum mixing height of 2,000 feet, and a wind speed equal to or greater than 5 mph.
One of the major problems with dividing the air basins into zones is the lack of data. It is often challenging to find data that represents an entire zone. Once we determine that there is sufficient data to comfortably make burn decisions based on the available meteorological data, we will begin testing the criteria. Our goal is to begin testing at the end of May. Meanwhile, ARB meteorology staff will communicate with Santa Barbara and Ventura counties to determine if changes should be made in those counties as well.
