Etude de la ventilation de la vallée de la Sarine en Gruyère

[摘要] A case study has been carried out in the Sarine valley inGruyere (Switzerland) in order to improve the understandingof thermotopographic winds over a complex terrain. Apartfrom field observations (fixed network, soundings, tracking ofconstant level balloons), two models have been tested withthe aim to apply these models in areas with a similar topography. The physical or laboratory model was able to createrealistic mountain or valley winds. The hydrostatic numericalmodel (MESOCONV) has been used to determine threedimensionalwind patterns for two important anticyclonicweather situations (with NE or SW synoptic winds).
