On the Effects of Islands' Geometry and Size on Inducing Sea Breeze Circulation
Publisher: American Meteorological Society
Abstract: Model scaling of the characteristics of the sea breeze circulation involved with circular and slab elongated-symmetric midlatitude islands was performed. Larger horizontal and vertical velocities were indicated over the ...
The Impact of Deep Cumulus Reflection on the Ground-Level Global Irradiance
Publisher: American Meteorological Society
Abstract: The magnitude of solar irradiance reflected from deep cumulus clouds to the ground was evaluated using observations along the Front Range of Colorado. Solar-irradiance reflection around noon was found to cause increases ...
On the Meteorological Conditions during Postprecipitation Periods: Implications to Pollutant Dispersion
Publisher: American Meteorological Society
Abstract: The various processes within the atmospheric boundary layer (ABL) during precipitation events tend to thermally stabilize the ABL. Selected observations are presented in order to illustrate this thermal stabilization for ...
Inferring Snow-Breeze Characteristics from Frozen-Lake Breezes
Publisher: American Meteorological Society
Abstract: Thermally induced flows between snow and snow-free areas (snow breezes) are difficult to evaluate by direct observations. This note outlines the equivalence of the surface thermal flux over snow and that over frozen/near-frozen ...
Nonclassical Mesoscale Circulations Caused by Surface Sensible Heat-Flux Gradients
Publisher: American Meteorological Society
Abstract: Significant spatial heterogeneities of daytime surface sensible heat flux are common over land within mesoscale domains. Thermally induced circulations, similar to the sea/lake breeze [termed nonclassical mesoscale ...
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 ...
Enhancement of Crosswind Pollutant Dispersion by Steadily Veering Winds in Sea Breezes
Publisher: American Meteorological Society
Abstract: An estimate is given of the relative importance of wind veering and turbulent diffusion in the mean horizontal spread of pollutant plumes in the atmosphere. Documented veering rates in sea breezes are used to illustrate ...
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 ...
Some Conceptual and Scaling Evaluations of Snowmelt Events Forced by Warm Soil
Publisher: American Meteorological Society
Abstract: Snowfall occasionally occurs over bare soil with high thermal storage in its upper layer. Quantification and generalization of the potential impact of the thermal storage on episodic snowmelt is evaluated using a scaling ...
