Breakup of Temperature Inversions in Deep Mountain Valleys: Part II. Thermodynamic Model
Publisher: American Meteorological Society
Abstract: A thermodynamic model is developed to simulate the evolution of vertical temperature structure during the breakup of nocturnal temperature inversions in mountain valleys. The primary inputs to the model are the valley floor ...
Diurnal Radiance Patterns of Finite and Semi-Infinite Clouds in Observations of Cloud Fields
Publisher: American Meteorological Society
Abstract: One of the important radiative effects of cloud Shape is to modify diurnal radiance patterns observed from satellites. Theory predicts a diurnal radiance pattern nearly symmetric about local noon for both semi-infinite and ...
Estimating Winter Design Temperatures from Daily Minimum Temperatures
Publisher: American Meteorological Society
Abstract: A methodology has been developed to estimate winter design temperatures (temperatures exceeded a specific number of hours during the December through February winter season-an important design parameter in building ...
Stratospheric Temperature Profiles from Limb Radiance Measurements
Publisher: American Meteorological Society
Abstract: Stlratospheric temperature profiles have been inferred from limb radiance data. The limb radiance observations were made from an Aerobee rocket flown on 7 February 1970 from White Sands Missile Range, N.M. The inferred ...
Deep Stable Layers in the Intermountain Western United States
Publisher: American Meteorological Society
Abstract: A deep stable layer (DSL) is a layer much deeper than a typical nocturnal inversion with stabilities not frequently found over a sizable portion of the lowest 1.5 km. They have traits that can cause the stagnation of cold ...
Effects of Shear, Stability and Valley Characteristics on the Destruction of Temperature Inversions
Publisher: American Meteorological Society
Abstract: A dry two-dimensional version of the Colorado State Cloud/Mesoscale Model was used to study the morning, inversion destruction cycle in a variety of deep mountain valley configurations. Eleven simulations were run to examine ...
Effects of Cloud Shape on Scattered Solar Radiation
Publisher: American Meteorological Society
Abstract: Calculations are presented which compare the effects on directional reflectance and relative radiance of changes in microphysical structure and geometric shape for scattered solar radiation in terrestrial water clouds. The ...
Scattering of Visible Radiation by Finite Clouds
Publisher: American Meteorological Society
Abstract: A theoretical model of the scattering of shortwave radiation is applied to clouds finite in horizontal extent. The resulting irradiance patterns are then compared with calculations for horizontally semi-infinite clouds. ...
Mesoscale Boundary-Layer Evolution over Complex Terrain. Part II: Factors Controlling Nocturnal Boundary-Layer Structure
Publisher: American Meteorological Society
Abstract: The development of the nocturnal boundary layer (NBL) over a sloping plateau upwind of a high mountain barrier is studied with a numerical model and field observations. Six numerical simulations and one observed case are ...
