Improved meteorology and surface fluxes in mesoscale modelling using adjusted initial vertical soil moisture profiles
2018
The Regional Atmospheric Modeling System (RAMS) is being used for different and diverse purposes, ranging from atmospheric and dispersion of pollutants forecasting to agricultural meteorology and ecological modelling as well as for hydrological purposes, among others. The current paper presents a comprehensive assessment of the RAMS forecasts, comparing the results not only with observed standard surface meteorological variables, measured at FLUXNET stations and other portable and permanent weather stations located over the region of study, but also with non-standard observed variables, such as the surface energy fluxes, with the aim of evaluating the surface energy budget and its relation …
Impact of Noah-LSM Parameterizations on WRF Mesoscale Simulations: Case Study of Prevailing Summer Atmospheric Conditions over a Typical Semi-Arid Re…

The current study evaluates the ability of the Weather Research and Forecasting Model (WRF) to forecast surface energy fluxes over a region in Eastern Spain. Focusing on the sensitivity of the model to Land Surface Model (LSM) parameterizations, we compare the simulations provided by the original Noah LSM and the Noah LSM with multiple physics options (Noah-MP). Furthermore, we assess the WRF sensitivity to different Noah-MP physics schemes, namely the calculation of canopy stomatal resistance (OPT_CRS), the soil moisture factor for stomatal resistance (OPT_BTR), and the surface layer drag coefficient (OPT_SFC). It has been found that these physics options strongly affect the energy partiti…
Influence of land cover in the atmospheric water vapor content and the generation of summer storms in the Turia River Basin

Les tronades d'estiu representen una font d’aigua important en la conca mediterrània, ja que aporten aigua durant els mesos més secs de l’any, amb la qual cosa ajuden a mantenir els cabdals dels principals rius. Aquests sistemes convectius estan associats a les circulacions de brisa que dominen durant l'estiu. La brisa es canalitza a través de les valls assolint les capçaleres dels principals rius on es generen línies de convergència, és a dir, zones on les masses d’aire superficials s’injecten a capes més altes de l’atmosfera i donen lloc a aquest tipus de fenòmens meteorològics. A part de la topografia, altres factors que poden influenciar la formació de tronades d'estiu són els fluxos su…
