| Zusammenfassung |
| We collected ground-based and aircraft vertical profile measurements of
meteorological parameters during a 2-week intensive campaign over the
Valencia basin, in order to understand how mesoscale circulations develop
over complex terrain and affect the atmospheric transport of tracers. A
high-resolution version of the RAMS model was run to simulate the campaign
and characterize the diurnal patterns of the flow regime: night-time
katabatic drainage, morning sea-breeze development and its subsequent
coupling with mountain up-slopes, and evening flow-veering under
larger-scale interactions. An application of this mesoscale model to
the transport of CO2 is given in a companion paper. A careful
evaluation of the model performances against diverse meteorological
observations is carried out. Despite the complexity of the processes
interacting with each other, and the uncertainties on modeled soil moisture
boundary conditions and turbulence parameterizations, we show that it is
possible to simulate faithfully the contrasted flow regimes during the
course of one day, especially the inland progression and organization of the
sea breeze. This gives confidence with respect to future applicability of
mesoscale models to establish a reliable link between surface sources of
tracers and their atmospheric concentration signals over complex terrain. |
