RISAn Idealized Comparison of One-Way and Two-Way Grid Nesting
Publisher: American Meteorological Society
Abstract: Most mesoscale models can be run with either one-way (parasitic) or two-way (interactive) grid nesting. This paper presents results from a linear 1D shallow-water model to determine whether the choice of nesting method can ...
Global-to-Regional Nested Grid Climate Simulations in the GFDL High Resolution Atmospheric Model
Publisher: American Meteorological Society
Abstract: two-way nested grid version of the Geophysical Fluid Dynamics Laboratory High Resolution Atmosphere Model (HiRAM) has been developed that uses simple methods for providing nested grid boundary conditions and mass-conserving ...
A Two-Way Nested Global-Regional Dynamical Core on the Cubed-Sphere Grid
Publisher: American Meteorological Society
Abstract: nested-grid model is constructed using the Geophysical Fluid Dynamics Laboratory finite-volume dynamical core on the cubed sphere. The use of a global grid avoids the need for externally imposed lateral boundary conditions, ...
Toward Convective-Scale Prediction within the Next Generation Global Prediction System
Publisher: American Meteorological Society
Abstract: AbstractThe Geophysical Fluid Dynamics Laboratory (GFDL) has developed a new variable-resolution global model with the ability to represent convective-scale features that serves as a prototype of the Next Generation Global ...
Improving Harvey Forecasts with Next-Generation Weather Satellites: Advanced Hurricane Analysis and Prediction with Assimilation of GOES-R All-Sky Radiances
Publisher: American Meteorological Society
Abstract: AbstractHurricane Harvey brought catastrophic destruction and historical flooding to the Gulf Coast region in late August 2017. Guided by numerical weather prediction models, operational forecasters at NOAA provided ...
Simulation and Prediction of Category 4 and 5 Hurricanes in the High-Resolution GFDL HiFLOR Coupled Climate Model
Publisher: American Meteorological Society
Abstract: new high-resolution Geophysical Fluid Dynamics Laboratory (GFDL) coupled model [the High-Resolution Forecast-Oriented Low Ocean Resolution (FLOR) model (HiFLOR)] has been developed and used to investigate potential skill ...
