RISA Case Study of GWE Satellite Data Impact on GLA Assimilation Analyses of Two Ocean Cyclones
Publisher: American Meteorological Society
Abstract: The impact of GWF satellite data on GLA analyses of the thermal structure of two oceanic extratropical cyclones are presented. The two storms developed nearly simultaneously in the western Pacific and Atlantic oceans during ...
The Measurement and Parameterization of Effective Radius of Droplets in Warm Stratocumulus Clouds
Publisher: American Meteorological Society
Abstract: Observations from the Meteorological Research Flight's Hercules C-130 aircraft of the microphysical characteristics of warm stratocumulus clouds have been analyzed to investigate the variation of the effective radius of ...
Parameterization of Wind Gustiness for the Computation of Ocean Surface Fluxes at Different Spatial Scales
Publisher: American Meteorological Society
Abstract: Analysis of the Goddard cloud-ensemble (GCE) model output forced by observational data over the tropical western Pacific and eastern tropical North Atlantic has shown that ocean surface latent and sensible heat fluxes ...
A Study of the Response of Deep Tropical Clouds to Large-Scale Thermodynamic Forcings. Part II: Sensitivities to Microphysics, Radiation, and Surface Fluxes
Publisher: American Meteorological Society
Abstract: The Goddard Cumulus Ensemble (GCE) model is used to examine the sensitivities of multiday 2D simulations of deep tropical convection to surface fluxes, interactive radiation, and ice microphysical processes. The simulations ...
Collisional Forcing of Raindrop Oscillations
Publisher: American Meteorological Society
Abstract: An energy model is formulated to compare collisional kinetic energy with viscous dissipation for oscillating raindrops as a function of size, raindrop distribution and rainfall rate. A potential energy model is used to ...
A Quasi-Lagrangian Diagnostic Case Study of the Effect of Satellite Sounding Data Assimilation on Model Cyclone Prediction
Publisher: American Meteorological Society
Abstract: The results of a quasi-Lagrangian diagnostic study of two 72 h Goddard Laboratory for Atmospheric Sciences (GLAS) model cyclone predictions from 0000 GMT 19 February 1976 are presented and compared with observed results. ...
A Compact, Low-Cost GPS Drifter for Use in the Oceanic Nearshore Zone, Lakes, and Estuaries
Publisher: American Meteorological Society
Abstract: The design of small, compact, low-cost GPS drifters that utilize ?off the shelf? components is described. The drifters are intended for use in confined or nearshore environments over time scales of up to several days and ...
On the Effect of Graphene Nanoplatelets on Water–Graphene Nanofluid Thermal Conductivity, Viscosity, and Heat Transfer Under Laminar External Flow Conditions
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experiments were conducted with graphene nanoplatelets (GNP) to investigate the relative benefit of the thermal conductivity increase in relationship to the potential detriment of increased viscosity. The maximum enhancement ...
The Atmospheric Energy Budget and Large-Scale Precipitation Efficiency of Convective Systems during TOGA COARE, GATE, SCSMEX, and ARM: Cloud-Resolving Model Simulations
Publisher: American Meteorological Society
Abstract: A two-dimensional version of the Goddard Cumulus Ensemble (GCE) model is used to simulate convective systems that developed in various geographic locations (east Atlantic, west Pacific, South China Sea, and Great Plains ...
The Collection and Analysis of Freshly Fallen Hailstones
Publisher: American Meteorological Society
Abstract: Attempts have been made to obtain samples of freshly fallen hailstones from severe storms in Oklahoma with the purpose of studying the nature and extent of spongy ice within natural hail. Interception by automobile of radar ...
