A Parameterization of Heterogeneous Land Surfaces for Atmospheric Numerical Models and Its Impact on Regional Meteorology
Publisher: American Meteorological Society
Abstract: Natural land surfaces are usually heterogeneous over the resolvable scales considered in atmospheric numerical models. Therefore, model surface parameterizations that assume surface homogeneity may fail to represent the ...
The Extrapolation of Vertical Profiles of Wind Speed within the Marine Atmospheric Surface layer Using the p Formula
Publisher: American Meteorological Society
Abstract: Values of p for the exponent-type wind profile formulation, used in vertical extrapolations of wind speed, were derived for the marine atmospheric surface layer. Nomograms were constructed providing p values as dependent ...
Application of a Numerical Mesoscale Model for the Evaluation of Seasonal Persistent Regional Climatological Patterns
Publisher: American Meteorological Society
Abstract: A three-dimensional numerical mesoscale model has been applied over the irregular terrain of northern Israel in order to simulate the local surface climate pattern associated with typical July stagnate synoptic meteorological ...
Vertical Heat Fluxes Generated by Mesoscale Atmospheric Flow Induced by Thermal Inhomogeneities in the PBL
Publisher: American Meteorological Society
Abstract: An analytical evaluation of the vertical heat fluxes associated with the mesoscale flow generated by thermal inhomogeneities in the PBL in the absence of a synoptic wind is presented. Results show that the mesoscale fluxes ...
Estimating the Fractal Dimension and the Predictability of the Atmosphere
Publisher: American Meteorological Society
Abstract: The fractal dimension, Lyapunov-exponent spectrum, Kolmogorov entropy, and predictability are analyzed for chaotic attractors in the atmosphere by analyzing the time series of daily surface temperature and pressure over ...
Horizontal Resolution Needs for Adequate Lower Tropospheric Profiling Involved with Atmospheric Systems Forced by Horizontal Gradients in Surface Heating
Publisher: American Meteorological Society
Abstract: For a propagating mesoscale system whose intensity and structure is not changing with time, relatively coarse horizontal profiler resolution is sufficient to resolve the feature since the circulation would pass by the ...
Scaling and Numerical Model Evaluation of Snow-Cover Effects on the Generation and Modification of Daytime Mesoscale Circulations
Publisher: American Meteorological Society
Abstract: Consideration of the sensible heat flux characteristics over a snow surface suggests a significant diminution in the magnitude of the flux, compared to that over a snow-free surface under the same environmental conditions. ...
The Impact of Wet Soil and Canopy Temperatures on Daytime Boundary–Layer Growth
Publisher: American Meteorological Society
Abstract: The impact of very wet soil and canopy temperatures on the surface sensible heat flux, and on related daytime boundary-layer properties is evaluated. For very wet soils, two winter situations are considered, related to ...
A Comparative Study of Daytime Thermally Induced Upslope Flow on Mars and Earth
Publisher: American Meteorological Society
Abstract: Several characteristics of thermally induced mesoscale upslope flow on Mars and its comparison with that on Earth were investigated using both analytical and numerical model approaches. The conclusions obtained from the ...
Effects of Atmospheric Thermal Stability and Slope Steepness on the Development of Daytime Thermally Induced Upslope Flow
Publisher: American Meteorological Society
Abstract: The impact of background atmospheric thermal stability and slope steepness on the daytime thermally induced upslope flows was investigated using analytical and numerical model approaches. The study focuses on meso-? domains ...
