Ground-Truth Model Evaluation of Subgrid Orographic Base-Flux Parameterization
Publisher: American Meteorological Society
Abstract: AbstractHigh-resolution simulation can be a powerful means of evaluating and tuning orographic drag schemes, but connecting the parameterized drag, which is a local forcing, with the model drag, which is fundamentally ...
27 Years of Regional Cooperation for Limited Area Modelling in Central Europe
Publisher: American Meteorological Society
Abstract: AbstractThis paper describes 27 years of scientific and operational achievement of Regional Cooperation for Limited Area Modelling in Central Europe (RC LACE), which is supported by the national (hydro-) meteorological ...
Results of the First Arctic Heat Open Science Experiment
Publisher: American Meteorological Society
Abstract: AbstractSeasonally ice-covered marginal seas are among the most difficult regions in the Arctic to study. Physical constraints imposed by the variable presence of sea ice in all stages of growth and melt make the upper ...
Climate Dependence in Empirical Parameters of Subgrid-Scale Parameterizations using the Fluctuation–Dissipation Theorem
Publisher: American Meteorological Society
Abstract: AbstractMany subgrid-scale (SGS) parameterizations in climate models contain empirical parameters and are thus data dependent. In particular, it is not guaranteed that the SGS parameterization still helps the model to ...
Concentric Eyewall Formation in Typhoon Sinlaku (2008). Part III: Horizontal Momentum Budget Analyses
Publisher: American Meteorological Society
Abstract: Abstract This is a follow-up work to two prior studies examining secondary eyewall formation (SEF) in Typhoon Sinlaku (2008). This study shows that, in the SEF region, the majority of the elevated winds are supergradient. ...
A Turbulence Scheme with Two Prognostic Turbulence Energies
Publisher: American Meteorological Society
Abstract: AbstractA new turbulence scheme with two prognostic energies is presented. The scheme is an extension of a turbulence kinetic energy (TKE) scheme following the ideas of Zilitinkevich et al. but valid for the whole stability ...
Improvement of the Simulation of Cloud Longwave Scattering in Broadband Radiative Transfer Models
Publisher: American Meteorological Society
Abstract: AbstractCloud longwave scattering is generally neglected in general circulation models (GCMs), but it plays a significant and highly uncertain role in the atmospheric energy budget as demonstrated in recent studies. To ...
A Comprehensive Observational Study of Graupel and Hail Terminal Velocity, Mass Flux, and Kinetic Energy
Publisher: American Meteorological Society
Abstract: AbstractThis study uses novel approaches to estimate the fall characteristics of hail, covering a size range from about 0.5 to 7 cm, and the drag coefficients of lump and conical graupel. Three-dimensional (3D) volume scans ...
The Impact of Mountain Waves on an Idealized Baroclinically Unstable Large-Scale Flow
Publisher: American Meteorological Society
Abstract: AbstractThe feedback of mountain waves and low-level blocking on an idealized baroclinically unstable wave passing over an isolated ridge is examined through numerical simulation. Theoretical analysis implies that the ...
The Competing Effects of Stability and Humidity on Subtropical Stratocumulus Entrainment and Cloud Evolution from a Lagrangian Perspective
Publisher: American Meteorological Society
Abstract: AbstractThe evolution of subtropical stratocumulus clouds and the boundary layer is studied on daily time scales from the Lagrangian perspective, following the flow. Measures of humidity above the boundary layer and of ...
