Abstract The paper describes the turbulence scheme implemented in Meso‐NH community research model, and reports on some validation studies. Since model is intended to perform both large‐eddy mesoscale simulations, we have developed a full three‐dimensional scheme, based original method of Redelsperger Sommeria. A prognostic equation for turbulent kinetic energy used, together with conservative variables moist non‐precipitating processes. particularity use variable Prandtl Schmidt numbers,...
This paper reports an intercomparison study on undisturbed trade wind cumulus convection under steady-state conditions as observed during the Barbados Oceanographic and Meteorological Experiment (BOMEX) with 10 large eddy simulation (LES) models. A main objective of this is to obtain a quantitative assessment quality turbulent dynamics for type boundary layer clouds produced by different LES codes. 6-h shows excellent model-to-model agreement vertical thermodynamical structure, reasonable...
The Cooperative Atmosphere–Surface Exchange Study—1999 (CASES-99) refers to a field experiment carried out in southeast Kansas during October 1999 and the subsequent program of investigation. Comprehensive data, primarily taken nighttime but typically including evening morning transition, supports data analyses, theoretical studies, state-of-the-art numerical modeling concerted effort by participants investigate four areas scientific interest. choice these topics is motivated both need...
The representation of the atmospheric boundary layer is an important part weather and climate models impacts many applications such as air quality wind energy. Over years, performance in modeling 2-m temperature 10-m speed has improved but errors are still significant. This particular case under clear skies low conditions at night well during winter stably stratified over land ice. In this paper, authors review these issues provide overview current understanding model performance. Results...

Abstract. Due to the major role of sun in heating earth's surface, atmospheric planetary boundary layer over land is inherently marked by a diurnal cycle. The afternoon transition, period day that connects daytime dry convective night-time stable layer, still has number unanswered scientific questions. This phase cycle challenging from both modelling and observational perspectives: it transitory, most forcings are small or null turbulence regime changes fully convective, close homogeneous...

Cloud‐top‐cooling rates weire chosen to be comparable those observed in marine stratocumulus, while avoiding evaporative feedbacks on entrainment turbulence that are also important liquid‐water clouds. radiative‐cooling rate hacl specified...

After Landsat 8 was launched in 2013, it observed that for Thermal Infrared sensor (TIRS) bands, radiance from outside of an instrument’s field-of-view produced a non-uniform ghost signal across the focal plane varied depending on out-of-scene content (i.e., stray light effect). A new correction algorithm (SLCA) is currently operational and has been implemented into United States Geological Survey (USGS) ground system since February 2017. The SLCA also applied to reprocess historical scenes....
Irrigation in semi-arid regions induces thermal heterogeneity across a range of spatial scales that impacts the partitioning energy at surface, development atmospheric boundary layer, and bidirectional interactions between atmosphere surface. In this analysis, we use data from Land Surface Interactions with Atmosphere Iberian Semi-Arid Environment (LIAISE) experiment combined coupled land–atmosphere model to understand role irrigation-induced, on surface fluxes consequently, diurnal...

Abstract The short-term forecasting of fog is a difficult issue that can have large societal impact. Radiation appears in the surface boundary layer, and its evolution driven by interactions between lower layers atmosphere. Current NWP models poorly forecast life cycle fog, improved are needed before improving prediction fog. Six numerical model simulations compared for two cases from Paris-Charles de Gaulle (Paris-CdG) field experiment. This intercomparison includes both operational...
