RISTemporal and Spatial Interpolation Errors of High-Resolution Modeled Atmospheric Fields
Publisher: American Meteorological Society
Abstract: eneral circulation models can now be run at very high spatial resolutions to capture finescale features, but saving the full-spatial-resolution output at every model time step is usually not practical because of storage ...
The Behavior of Gravitational Modes in Numerical Forecasts with the NCAR Community Climate Model
Publisher: American Meteorological Society
Abstract: Characteristics of gravitational-wave noise in noninitialized forecasts were investigated with the NCAR Community Climate Model. Forecasts were begun from FGGE analyses. The behavior of individual, gravitational normal ...
Uncertainty of Observation Impact Estimation in an Adjoint Model Investigated with an Observing System Simulation Experiment
Publisher: American Meteorological Society
Abstract: AbstractAdjoint models are often used to estimate the impact of different observations on short-term forecast skill. A common difficulty with the evaluation of short-term forecast quality is the choice of verification ...
The Impact of Increased Frequency of Rawinsonde Observations on Forecast Skill Investigated with an Observing System Simulation Experiment
Publisher: American Meteorological Society
Abstract: ost rawinsondes are launched once or twice daily, at 0000 and/or 1200 UTC; only a small number of the total rawinsonde observations are taken at 0600 and 1800 UTC (?off hour? cycle times). In this study, the variations of ...
