Fecha de publicación: | mar-2012 | Editor: | American Meteorological Society | Citación: | Jiménez, Pedro A., Jimy Dudhia, J. Fidel González-Rouco, Jorge Navarro, Juan P. Montávez, Elena García-Bustamante, 2012: A Revised Scheme for the WRF Surface Layer Formulation. Monthly Weather Review, 140, 898–918. doi: http://dx.doi.org/10.1175/MWR-D-11-00056.1 | Resumen: | This study summarizes the revision performed on the surface layer formulation of the Weather Research and Forecasting (WRF) model. A first set of modifications are introduced to provide more suitable similarity functions to simulate the surface layer evolution under strong stable/unstable conditions. A second set of changes are incorporated to reduce or suppress the limits that are imposed on certain variables in order to avoid undesired effects (e.g., a lower limit in u*). The changes introduced lead to a more consistent surface layer formulation that covers the full range of atmospheric stabilities. The turbulent fluxes are more (less) efficient during the day (night) in the revised scheme and produce a sharper afternoon transition that shows the largest impacts in the planetary boundary layer meteorological variables. The most important impacts in the near-surface diagnostic variables are analyzed and compared with observations from a mesoscale network. | Versión del editor: | http://dx.doi.org/10.1175/MWR-D-11-00056.1 | URI: | http://hdl.handle.net/10261/75949 | DOI: | 10.1175/MWR-D-11-00056.1 |
