Modeling the role of lake breeze transport on ozone concentrations in southern Ontario
- York Univ., North York, Ontario (Canada)
This study makes use of a modified version of the Mesoscale Compressible Community model (MC2), a fully compressible, non-hydrostatic meteorological model, to study the effects of the lake breeze circulation on the formation and distribution of high levels of ozone in south-eastern Ontario. Transport, photochemistry, emission, and deposition modules, based on the Acid Deposition and Oxidants Model (ADOM), have been added to the MC2 model. Chemistry is run on-line with the meteorology. While making greater demands on computing power, running the chemistry in-line alleviates, to some extent, the need for storage of large meteorological fields and potentially allows for greater consistency between the dynamical fields produced by the meteorology and the advection of trace gas species. The model can be run in a nested manner to allow a high resolution study of the interaction of lake breeze circulations with ozone precursor laden plumes of air leaving Toronto. The model has been successfully run for the first twenty days of August 1988 at a horizontal resolution of 21km. Modeling studies of lake breezes at a 5km resolution have been limited to meteorological only runs so far.
