| Zusammenfassung |
| The evolution of the thermodynamic structure of the atmospheric boundary layer over and in
the vicinity of the Alqueva reservoir, a 250 km2 man made lake in south Portugal, is studied
using mesoscale simulations and observations.
The Observations were carried out during the intensive period (IOP) of the ALqueva
hydro-meteorological Experiment, ALEX 2014 (www.alex2014.cge.uevora.pt), which took
place between 22 and 24 July 2014. Twomodels were used, and the results have been
inter-compared: The Weather Research and Forecasting, WRF, andthe non-hydrostatic
Meso-NH.
During the ALEX 2014 IOP, radiosondes were launched every tree hours and the near surface
fluxes of energy, vapor and momentum were measured using an eddy covariance system
installed on a floating platform in the lake.
The ALEX field campaign includes also several surface meteorological stations, over
water and land in order to characterize the local horizontal structure of the surface
layer.
The simulations, validated by the observations, allows the study of the effects of the lake in
the boundary layer and on the atmospheric flow. |
