RISA Study of Cold-Air Modification over the Gulf of Mexico Using In Situ Data and Mixed-Layer Modeling
Publisher: American Meteorological Society
Abstract: The evolution of the mean characteristics of the marine boundary layer during cold-air outbreaks can be described with an integrated or slab model. In order to assess the practical applicability of this-type of model to ...
Modeling of Stratocumulus Cloud Layers in a Large Eddy Simulation Model with Explicit Microphysics
Publisher: American Meteorological Society
Abstract: A new large eddy simulation (LES) stratocumulus cloud model with an explicit formulation of micro-physical processes has been developed, and the results from three large eddy simulations are presented to illustrate the ...
Variational Optimization Method for Calculation of Cloud Drop Growth in an Eulerian Drop-Size Framework
Publisher: American Meteorological Society
Abstract: A variational optimization (VO) method that requires specification of only one variable in each bin size for condensation and evaporation calculations in an Eulerian drop-size framework is proposed. The method is tested ...
Evaluation of Storm Structure from the Operational HWRF during 2012 Implementation
Publisher: American Meteorological Society
Abstract: n this work, a high-resolution triple-nested implementation of the National Centers for Environmental Prediction (NCEP) operational Hurricane Weather Research and Forecasting Model (HWRF) for the 2012 hurricane season is ...
Modeling of Ship Effluent Transport and Its Sensitivity to Boundary Layer Structure
Publisher: American Meteorological Society
Abstract: The LES model is applied for studying ship track formation under various boundary layer conditions observed during the Monterey Area Ship Track experiment. Simulations in well-mixed and decoupled boundary layers show that ...
Forecasting Tropical Cyclones in the Western North Pacific Basin Using the NCEP Operational HWRF Model: Model Upgrades and Evaluation of Real-Time Performance in 2013
Publisher: American Meteorological Society
Abstract: his study presents evaluation of real-time performance of the National Centers for Environmental Prediction (NCEP) operational Hurricane Weather Research and Forecast (HWRF) modeling system upgraded and implemented in 2013 ...
Representing Multiple Scales in the Hurricane Weather Research and Forecasting Modeling System: Design of Multiple Sets of Movable Multilevel Nesting and the Basin-Scale HWRF Forecast Application
Publisher: American Meteorological Society
Abstract: n this study, the design of movable multilevel nesting (MMLN) in the Hurricane Weather Research and Forecasting (HWRF) modeling system is documented. The configuration of a new experimental HWRF system with a much larger ...
Forecasting Tropical Cyclones in the Western North Pacific Basin Using the NCEP Operational HWRF: Real-Time Implementation in 2012
Publisher: American Meteorological Society
Abstract: his study documents the recent efforts of the hurricane modeling team at the National Centers for Environmental Prediction?s (NCEP) Environmental Modeling Center (EMC) in implementing the operational Hurricane Weather ...
Impact of Assimilating Aircraft Reconnaissance Observations on Tropical Cyclone Initialization and Prediction Using Operational HWRF and GSI Ensemble–Variational Hybrid Data Assimilation
Publisher: American Meteorological Society
Abstract: AbstractThis study evaluates the impact of assimilating high-resolution, inner-core reconnaissance observations on tropical cyclone initialization and prediction in the 2013 version of the operational Hurricane Weather ...
Drizzle Suppression in Ship Tracks
Publisher: American Meteorological Society
Abstract: Although drizzle was a relatively infrequent occurrence during the Monterey Area Ship Track study, diverse measurements from several sources produced data signals consistent with a reduction in drizzle drops in stratus ...
