RISVolume Scanning Strategies for 3D Wind Retrieval from Dual-Doppler Lidar Measurements
Publisher: American Meteorological Society
Abstract: Dual-Doppler lidar volume scans for 3D wind retrieval must accommodate the conflicting goals of dense spatial coverage and short scan duration. In this work, various scanning strategies are evaluated with semisynthetic ...
The Convective Boundary Layer in the Terra Incognita
Publisher: American Meteorological Society
Abstract: umerical simulations of a convective boundary layer (CBL) are performed to investigate model behavior in the terra incognita, also known as the gray zone. The terra incognita of the CBL refers to a range of model grid ...
High-Resolution Large-Eddy Simulations of Flow in a Steep Alpine Valley. Part II: Flow Structure and Heat Budgets
Publisher: American Meteorological Society
Abstract: This paper analyzes the three-dimensional flow structure and the heat budget in a typical medium-sized and steep Alpine valley?the Riviera Valley in southern Switzerland. Aircraft measurements from the Mesoscale Alpine ...
External Influences on Nocturnal Thermally Driven Flows in a Deep Valley
Publisher: American Meteorological Society
Abstract: The dynamics that govern the evolution of nighttime flows in a deep valley, California?s Owens Valley, are analyzed. Measurements from the Terrain-Induced Rotor Experiment (T-REX) reveal a pronounced valley-wind system ...
A New Vertical Grid Nesting Capability in the Weather Research and Forecasting (WRF) Model
Publisher: American Meteorological Society
Abstract: esoscale atmospheric models are increasingly used for high-resolution (<3 km) simulations to better resolve smaller-scale flow details. Increased resolution is achieved using mesh refinement via grid nesting, a procedure ...
Topographic Effects on Radiation in the WRF Model with the Immersed Boundary Method: Implementation, Validation, and Application to Complex Terrain
Publisher: American Meteorological Society
Abstract: AbstractTopographic effects on radiation, including both topographic shading and slope effects, are included in the Weather Research and Forecasting (WRF) Model, and here they are made compatible with the immersed boundary ...
Generalized Empirical Regret Bounds for Control of Renewable Energy Systems in Spatiotemporally Varying Environments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on the empirical derivation of regret bounds for mobile systems that can optimize their locations in real-time within a spatiotemporally varying renewable energy resource. The case studies in this paper ...
Bayesian Inference and Markov Chain Monte Carlo Sampling to Reconstruct a Contaminant Source on a Continental Scale
Publisher: American Meteorological Society
Abstract: A methodology combining Bayesian inference with Markov chain Monte Carlo (MCMC) sampling is applied to a real accidental radioactive release that occurred on a continental scale at the end of May 1998 near Algeciras, Spain. ...
Intercomparison of Mesoscale Model Simulations of the Daytime Valley Wind System
Publisher: American Meteorological Society
Abstract: hree-dimensional simulations of the daytime thermally induced valley wind system for an idealized valley?plain configuration, obtained from nine nonhydrostatic mesoscale models, are compared with special emphasis on the ...
