Abstract: | Variation exists in the maximum mixing height (MMH) across the coastal zone because of major differences in heat capacity
between land and sea. By assuming that synoptic and microscale effects are all small as compared to the contribution from
mesoscale temperature differences, a model is proposed to explain this variation. The model states that the variation of the
MMH across the coastal zone is due primarily and is linearly proportional to the difference in maximum temperature between
land and sea. Since the MMH is one of the most important parameters in the computation of distribution and concentration of
aerosols, water vapor, and pollutants, a simple equation is also provided for the operational forecasting of the MMH or the
mixing height over the sea. All inputs into the equation are routinely available. The model has been verified by available
data and a relevant field experiment. |
