High-Resolution Large-Eddy Simulations of Flow in a Steep Alpine Valley. Part II: Flow Structure and Heat Budgets
(American Meteorological Society, 2006)This paper analyzes the three-dimensional flow structure and the heat budget in a typical medium-sized and steep Alpine valley?the Riviera Valley in southern Switzerland. Aircraft measurements from the Mesoscale Alpine ... -
Contrails to Cirrus—Morphology, Microphysics, and Radiative Properties
(American Meteorological Society, 2006)This work is two pronged, discussing 1) the morphology of contrails and their transition to cirrus uncinus, and 2) their microphysical and radiative properties. It is based upon the fortuitous occurrence of an unusual set ... -
Objective Assessment of the Information Content of Visible and Infrared Radiance Measurements for Cloud Microphysical Property Retrievals over the Global Oceans. Part II: Ice Clouds
(American Meteorological Society, 2006)Cirrus clouds play an important yet poorly determined role in the earth?s climate system and its various feedback mechanisms. As such, a significant amount of work has been accomplished both in understanding the physics ... -
Effect of Air Pollution on Precipitation along the Front Range of the Rocky Mountains
(American Meteorological Society, 2006)Air pollution generated in industrial and urban areas can act to suppress precipitation by creating a narrow cloud droplet spectrum, which inhibits the collision and coalescence process. In fact, precipitation ratios of ... -
Bridge Frost Prediction by Heat and Mass Transfer Methods
(American Meteorological Society, 2006)Frost on roadways and bridges can present hazardous conditions to motorists, particularly when it occurs in patches or on bridges when adjacent roadways are clear of frost. To minimize materials costs, vehicle corrosion, ... -
On Improving 4-km Mesoscale Model Simulations
(American Meteorological Society, 2006)A previous study showed that use of analysis-nudging four-dimensional data assimilation (FDDA) and improved physics in the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale ... -
Parameterization of the Urban Water Budget with the Submesoscale Soil Model
(American Meteorological Society, 2006)This paper presents the hydrological component of the Submesoscale Soil Model, urbanized version (SM2-U). This model is an extension of the rural Interactions between Soil, Biosphere, and Atmosphere (ISBA) soil model to ... -
The Antalya 5 December 2002 Storm: Observations and Model Analysis
(American Meteorological Society, 2006)In the frame of this work, the storm that occurred on 5 December 2002 in Antalya, located on the southwestern Mediterranean Sea coast of Turkey, is analyzed. More than 230 mm of 24-h-accumulated rainfall have been reported ... -
Evaluating a Hybrid Prognostic–Diagnostic Model That Improves Wind Forecast Resolution in Complex Coastal Topography
(American Meteorological Society, 2006)The results from a hybrid approach that combines the forecasts of a mesoscale model with a diagnostic wind model to produce high-resolution wind forecasts in complex coastal orography are evaluated. The simple diagnostic ... -
An Approach for Calculation of Turbulent Transfer Coefficient for Momentum inside Vegetation Canopies
(American Meteorological Society, 2006)A method for calculating the profile of turbulent transfer coefficient for momentum inside a vegetation canopy for use in land surface schemes is presented. It is done through the following steps. First, an equation for ... -
Validation of a Receptor–Dispersion Model Coupled with a Genetic Algorithm Using Synthetic Data
(American Meteorological Society, 2006)A methodology for characterizing emission sources is presented that couples a dispersion and transport model with a pollution receptor model. This coupling allows the use of the backward (receptor) model to calibrate the ... -
Correcting Active Scatterometer Data for the Effects of Rain Using Passive Radiometer Data
(American Meteorological Society, 2006)A model for the effects of rain on scatterometer data is proposed. Data from the Advanced Microwave Scanning Radiometer (AMSR) and the SeaWinds scatterometer, both on the Midori-II satellite, are used. The model includes ... -
Area-Averaged Surface Fluxes in a Semiarid Region with Partly Irrigated Land: Lessons Learned from EFEDA
(American Meteorological Society, 2006)The European Field Experiment in a Desertification-Threatened Area (EFEDA) provides a comprehensive land surface dataset for a semiarid Mediterranean environment with natural vegetation and cultivated dry and irrigated ... -
Snowmelt-Related Flood Risk in Appalachia: First Estimates from a Historical Snow Climatology
(American Meteorological Society, 2006)A first attempt has been made toward quantifying the risk of snowmelt-related flooding in the central and southern Appalachian Mountains of the United States (from 35° to 42°N). In the last decade, two major events occurred ... -
Rain Retrieval from TMI Brightness Temperature Measurements Using a TRMM PR–Based Database
(American Meteorological Society, 2006)This study focuses on improving the retrieval of rain from measured microwave brightness temperatures and the capability of the retrieved field to represent the mesoscale structure of a small intense hurricane. For this ... -

Inconsistencies in the “New” Windchill Chart at Low Wind Speeds
(American Meteorological Society, 2006)An apparent error was detected in the calculation of windchill equivalent temperatures (WCETs) in the ?new? chart and corresponding equation that were adopted in 2001 by the weather services in the United States and Canada. ... -
Bayesian Estimation of Precipitation from Satellite Passive Microwave Observations Using Combined Radar–Radiometer Retrievals
(American Meteorological Society, 2006)Precipitation estimation from satellite passive microwave radiometer observations is a problem that does not have a unique solution that is insensitive to errors in the input data. Traditionally, to make this problem well ... -
Rainfall Climate Regimes: The Relationship of Regional TRMM Rainfall Biases to the Environment
