摘要: Meteorological modelling in the planetary boundary layer (PBL) over Greater Paris is performed using Weather Research and Forecast (WRF) numerical model. The simulated meteorological fields are evaluated by comparison with mean diurnal observational data or vertical profiles of temperature, wind speed, humidity boundary-layer height from 6 to 27 May 2005. Different PBL schemes, which parametrize atmospheric turbulence different closure may be used WRF sensitivity results four schemes (two non-local two local schemes) estimated. Uncertainties compared influence urban canopy model (UCM) updated Coordination Information on Environment (CORINE) land-use data. Using UCM CORINE produces more realistic modelled fields. overestimated simulations without UCM, improved below 1,000 m height. Furthermore, heights during nighttime strongly modified, an increase that as high 200 %. At night, impact changing scheme lower than
