A First-Order Closure for Covariances and Fluxes of Reactive Species in the Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: Covariances and fluxes of reactive species in the clear convective atmospheric boundary layer (CABL) are studied and parameterized. The covariances result from correlations between reactive species. These covariances may ...
Real-Time Water Vapor Maps from a GPS Surface Network: Construction, Validation, and Applications
Publisher: American Meteorological Society
Abstract: In this paper the construction of real-time integrated water vapor (IWV) maps from a surface network of global positioning system (GPS) receivers is presented. The IWV maps are constructed using a two-dimensional variational ...
Area-Averaged Surface Fluxes in a Semiarid Region with Partly Irrigated Land: Lessons Learned from EFEDA
Publisher: American Meteorological Society
Abstract: The European Field Experiment in a Desertification-Threatened Area (EFEDA) provides a comprehensive land surface dataset for a semiarid Mediterranean environment with natural vegetation and cultivated dry and irrigated ...
Performance of HIRLAM in a Semiarid Heterogeneous Region: Evaluation of the Land Surface and Boundary Layer Description Using EFEDA Observations
Publisher: American Meteorological Society
Abstract: Observations from the European Field Experiment in a Desertification-threatened Area (EFEDA) are used to evaluate the performance of the radiation, land surface, and boundary layer description of the numerical weather ...
Dispersion of a Passive Tracer in Buoyancy- and Shear-Driven Boundary Layers
Publisher: American Meteorological Society
Abstract: By means of finescale modeling [large-eddy simulation (LES)], the combined effect of thermal and mechanical forcing on the dispersion of a plume in a convective boundary layer is investigated. Dispersion of a passive tracer ...
Land Surface Feedbacks on Spring Precipitation in the Netherlands
Publisher: American Meteorological Society
Abstract: n this paper, the Weather Research and Forecasting (WRF) Model is used to investigate the sensitivity of precipitation to soil moisture and urban areas in the Netherlands. The average output of a 4-day event during 10?13 ...
Relating Eulerian and Lagrangian Statistics for the Turbulent Dispersion in the Atmospheric Convective Boundary Layer
Publisher: American Meteorological Society
Abstract: Eulerian and Lagrangian statistics in the atmospheric convective boundary layer (CBL) are studied by means of large eddy simulation (LES). Spectra analysis is performed in both the Eulerian and Lagrangian frameworks, ...
Surface and Atmospheric Controls on the Onset of Moist Convection over Land
Publisher: American Meteorological Society
Abstract: he onset of moist convection over land is investigated using a conceptual approach with a slab boundary layer model. The authors determine the essential factors for the onset of boundary layer clouds over land and study ...
Opportunistic Sensing with Recreational Hot-Air Balloon Flights
Publisher: American Meteorological Society
An Automated Microlysimeter to Study Dew Formation and Evaporation in Arid and Semiarid Regions
Publisher: American Meteorological Society
Abstract: The development of a simple and low-cost portable weighing microlysimeter that makes use of a load cell for automated recording and for studying daily dew formation, rate of accumulation, and subsequent evaporation in arid ...
