RISEstimating the Intrinsic Limit of Predictability Using a Stochastic Convection Scheme
Publisher: American Meteorological Society
Abstract: Global model simulations together with a stochastic convection scheme are used to assess the intrinsic limit of predictability that originates from convection up to planetary scales. The stochastic convection scheme has ...
Upscale Error Growth in a High-Resolution Simulation of a Summertime Weather Event over Europe
Publisher: American Meteorological Society
Abstract: he growth of small-amplitude, spatially uncorrelated perturbations has been studied in a weather forecast of a 4-day period in the summer of 2007, using a large domain covering Europe and the eastern Atlantic and with ...
Structure Function Analysis of Water Vapor Simulated with a Convection-Permitting Model and Comparison to Airborne Lidar Observations
Publisher: American Meteorological Society
Abstract: AbstractThe spatial scale dependence of midlatitude water vapor variability in the high-resolution limited-area model COSMO is evaluated using diagnostics of scaling behavior. Past analysis of airborne lidar measurements ...
Convective and Slantwise Trajectory Ascent in Convection-Permitting Simulations of Midlatitude Cyclones
Publisher: American Meteorological Society
Abstract: ir parcel ascent in midlatitude cyclones driven by latent heat release has been investigated using convection-permitting simulations together with an online trajectory calculation scheme. Three cyclones were simulated to ...
Variability and Clustering of Midlatitude Summertime Convection: Testing the Craig and Cohen Theory in a Convection-Permitting Ensemble with Stochastic Boundary Layer Perturbations
Publisher: American Meteorological Society
Abstract: AbstractThe statistical theory of convective variability developed by Craig and Cohen in 2006 has provided a promising foundation for the design of stochastic parameterizations. The simplifying assumptions of this theory, ...
Estimation of the Variability of Mesoscale Energy Spectra with Three Years of COSMO-DE Analyses
Publisher: American Meteorological Society
Abstract: Research on the mesoscale kinetic energy spectrum over the past few decades has focused on finding a dynamical mechanism that gives rise to a universal spectral slope. Here we investigate the variability of the spectrum ...
Quantitative View on the Processes Governing the Upscale Error Growth up to the Planetary Scale Using a Stochastic Convection Scheme
Publisher: American Meteorological Society
Abstract: AbstractTwo diagnostics based on potential vorticity and the envelope of Rossby waves are used to investigate upscale error growth from a dynamical perspective. The diagnostics are applied to several cases of global, ...
