TAPM demonstrates many advantages such as three-dimensional prognostic modeling, predicting both meteorological and air pollution fields, predicting hour by hour pollution concentrations for periods of up to a year, and predicting the flows important to local-scale air pollution such as sea breezes and terrain induced flows. But TAPM has a tendency to overestimate surface wind speed over urban areas during stagnant nocturnal conditions, resulting in quick flushing of pollutants (Zawar-Reza et al., 2005).
