Zusammenfassung |
Some of the meteorological approaches commonly considered in urban air
pollution models do not take into account the importance of the smaller
scales in the meteorology of complex-terrain coastal sites. The aim of this
work is to estimate the impact of using the proper meteorological scales
when simulating the behaviour of the pollutant concentrations emitted in the
lower layers over coastal complex terrain areas. The availability of
experimental measurements of a power plant plume near the Castellón
conurbation (on the Spanish Mediterranean coast) has allowed us to use this
plume as a tracer of opportunity of the lower atmosphere to check the
results of a simulation exercise using the RAMS mesoscale model coupled to
the HYPACT particle model. The results obtained show that in a
complex-terrain coastal site, because of the strong effect of the
meteorological interactions between the different scales on the integral
advection and the turbulent dispersion of pollutants, using an inadequate
scale to solve the meteorology can result in a very big gap in the
simulation of lower-layer pollutant behaviour at urban scales. |
