RISA Double-Moment Multiple-Phase Four-Class Bulk Ice Scheme. Part I: Description
Publisher: American Meteorological Society
Abstract: A detailed ice-phase bulk microphysical scheme has been developed for simulating the hydrometeor distributions of convective and stratiform precipitation in different large-scale environmental conditions. The proposed ...
Asymptotic Analysis of Equilibrium in Radiation Fog
Publisher: American Meteorological Society
Abstract: A vertical distribution formulation of liquid water content (LWC) for steady radiation fog was obtained and examined through the singular perturbation method. The asymptotic LWC distribution is a consequential balance among ...
One-Dimensional Time-Dependent Modeling of GATE Cumulonimbus Convection
Publisher: American Meteorological Society
Abstract: A one-dimensional time-dependent cumulonimbus model is designed that, unlike in previous one-dimensional models, simulates cloud-top heights, vertical velocities, and water contents that are reasonably consistent with those ...
A Double-Moment Multiple-Phase Four-Class Bulk Ice Scheme. Part II: Simulations of Convective Storms in Different Large-Scale Environments and Comparisons with other Bulk Parameterizations
Publisher: American Meteorological Society
Abstract: Part I of this study described a detailed four-class bulk ice scheme (4ICE) developed to simulate the hydro-meteor profiles of convective and stratiform precipitation associated with mesoscale convective systems. In Part ...
Sensitivity of Tropical West Pacific Oceanic Squall Lines to Tropospheric Wind and Moisture Profiles
Publisher: American Meteorological Society
Abstract: Two-dimensional experiments using the Goddard Cumulus Ensemble model are performed in order to examine the influence of environmental profiles of wind and humidity on the dynamical and microphysical structure of mesoscale ...
Rainfall Morphology in Florida Convergence Zones: A Numerical Study
Publisher: American Meteorological Society
Abstract: Central Florida is the ideal test laboratory for studying convergence zone?induced convection. The region regularly experiences sea-breeze fronts and rainfall-induced outflow boundaries. The focus of this study is convection ...
Establishing Closer Collaboration to Improve Model Physics for Short-Range Forecasts
Publisher: American Meteorological Society
Factors Responsible for Precipitation Efficiencies in Midlatitude and Tropical Squall Simulations
Publisher: American Meteorological Society
Abstract: Different definitions of storm precipitation efficiency were investigated from numerical simulators of convective systems in widely varying ambient conditions using a two-dimensional cloud model with sophisticated ice ...
Modified NAM Microphysics for Forecasts of Deep Convective Storms
Publisher: American Meteorological Society
Abstract: AbstractThe Ferrier?Aligo (FA) microphysics scheme has been running operationally in the National Centers for Environmental Prediction (NCEP) North American Mesoscale Forecast System (NAM) since August 2014. It was developed ...
An Ensemble of Convective Systems on 11 February 1993 during TOGA COARE:Morphology, Rainfall Characteristics, and Anvil Cloud Interactions
Publisher: American Meteorological Society
Abstract: An active day during the Coupled Ocean?Atmosphere Response Experiment (COARE) Intensive Observation Period (IOP) is examined in which nine convective systems evolved and moved eastward across the region of shipboard radar ...
