Microphysical and Optical Properties of Atmospheric Ice Crystals at South Pole Station
(American Meteorological Society, 2006)In early February 2001 (during the austral summer), over 900 000 digital images of ice crystals were recorded at the South Pole using two ground-based cloud particle imagers (CPIs). Of these, 721 572 crystals >50 ?m were ... -
Variation of Surface Air Temperature in Complex Terrain
(American Meteorological Society, 2006)Data from three micronetworks with eddy correlation data and three additional micronetworks without eddy correlation data are analyzed to study the spatial variability of surface air temperature in complex terrain. A simple ... -
Winter-Season Climate Prediction for the U.K. Health Sector
(American Meteorological Society, 2006)The winter climate of the British Isles is characterized by considerable interannual variability, which, because of the general climate sensitivity of a number of health outcomes, places at times considerable pressure on ... -
Understanding the Influence of Climate Forecasts on Farmer Decisions as Planned Behavior
(American Meteorological Society, 2006)Results of a set of four regression models applied to recent survey data of farmers in eastern Nebraska suggest the causes that drive farmer intentions of using weather and climate information and forecasts in farming ... -
Understanding Farmers’ Forecast Use from Their Beliefs, Values, Social Norms, and Perceived Obstacles
(American Meteorological Society, 2006)Although the accuracy of weather and climate forecasts is continuously improving and new information retrieved from climate data is adding to the understanding of climate variation, use of the forecasts and climate information ... -
Coevolution of Down-Valley Flow and the Nocturnal Boundary Layer in Complex Terrain
(American Meteorological Society, 2006)An enhanced National Center for Atmospheric Research (NCAR) integrated sounding system (ISS) was deployed as part of the Vertical Transport and Mixing (VTMX) field experiment, which took place in October of 2000. The ... -
A Simple Model for Simulating Tornado Damage in Forests
(American Meteorological Society, 2006)An analytical model is presented to describe patterns of downed trees produced by tornadic winds. The model uses a combined Rankine vortex of specified tangential and radial components to describe a simple tornado circulation. ... -
Parameterization of the Urban Energy Budget with the Submesoscale Soil Model
(American Meteorological Society, 2006)The thermal component of the Soil Model for Submesoscales, Urbanized Version (SM2-U), is described. SM2-U is an extension on a physical basis of the rural Interactions between Soil, Biosphere, and Atmosphere (ISBA) soil ... -
Does the Influence of Oblate-Like Distortions in Larger Raindrops Make a Difference in Collection and Evaporation Parameterizations?
(American Meteorological Society, 2006)This note documents the results of more exact parameterizations for continuous-collection growth and evaporation against simpler traditional ones. Although the main focus is on improving research models, the research results ... -
Thermally and Dynamically Induced Pressure Features over Complex Terrain from High-Resolution Analyses
(American Meteorological Society, 2007)Within the Vienna Enhanced Resolution Analysis (VERA) Climatology (VERACLIM) project, the complex influence of topographic structures on the spatial distribution of meteorological parameters has been investigated and ... -
Fuzzy Rule–Based Approach for Detection of Bounded Weak-Echo Regions in Radar Images
(American Meteorological Society, 2006)A method for the detection of a bounded weak-echo region (BWER) within a storm structure that can help in the prediction of severe weather phenomena is presented. A fuzzy rule?based approach that takes care of the various ... -
Analysis and Application of Sheppard’s Airflow Model to Predict Mechanical Orographic Lifting and the Occurrence of Mountain Clouds
(American Meteorological Society, 2006)Mechanically driven orographic lifting is important for air pollution dispersion and weather prediction, but the small dimensions of mountain peaks often prevent numerical weather models from producing detailed forecasts. ... -
Development and Testing of Tropical Cyclone Parametric Wind Models Tailored for Midlatitude Application—Preliminary Results
(American Meteorological Society, 2006)Over the years, researchers have developed parametric wind models to depict the surface winds within a tropical cyclone (TC). Most models were developed using data from aircraft flights into low-latitude (south of 30°N) ... -
Comparisons of Transport and Dispersion Model Predictions of the Mock Urban Setting Test Field Experiment
(American Meteorological Society, 2006)The potential effects of a terrorist attack involving the atmospheric release of chemical, biological, radiological, nuclear, or other hazardous materials continue to be of concern to the United States. The Defense Threat ... -
The Successive-Order-of-Interaction Radiative Transfer Model. Part II: Model Performance and Applications
(American Meteorological Society, 2006)Radiative transfer models for scattering atmospheres that are accurate yet computationally efficient are required for many applications, such as data assimilation in numerical weather prediction. The successive-order-of- ... -
NEOPLANTA: A Short Description of the First Serbian UV Index Model
(American Meteorological Society, 2006)A numerical model called ?NEOPLANTA? for estimating solar UV irradiance and UV index under cloud-free conditions is being developed and tested at the University of Novi Sad in Serbia. In this paper, the model features, ... -
Using Climate Forecasts for Drought Management
