A Synoptic Climatology of Summertime Heat and Humidity in the Piedmont Region of North Carolina
(American Meteorological Society, 2006)The synoptic patterns and boundary layer conditions over a range of antecedent periods associated with the summertime hot events for the years 1951?93 are examined. A hot event is defined as a single day with the highest ... -
A Simple, Efficient Solution of Flux–Profile Relationships in the Atmospheric Surface Layer
(American Meteorological Society, 2006)This note describes a simple scheme for analytical estimation of the surface-layer similarity functions from state variables. What distinguishes this note from the many previous papers on this topic is that this method is ... -
The Retrieval of Ice Water Content from Radar Reflectivity Factor and Temperature and Its Use in Evaluating a Mesoscale Model
(American Meteorological Society, 2006)Ice clouds are an important yet largely unvalidated component of weather forecasting and climate models, but radar offers the potential to provide the necessary data to evaluate them. First in this paper, coordinated ... -
Critical Assessment of Microphysical Assumptions within TRMM Radiometer Rain Profile Algorithm Using Satellite, Aircraft, and Surface Datasets from KWAJEX
(American Meteorological Society, 2006)The Tropical Rainfall Measuring Mission (TRMM) Microwave Imager precipitation profile retrieval algorithm (2a12) assumes cloud model?derived vertically distributed microphysics as part of the radiative transfer?controlled ... -
Measuring Atmospheric Stability with GPS
(American Meteorological Society, 2006)Nowcasting of convective systems plays a crucial role in weather forecasting. The strength of convection depends on the (in)stability of the air column. The stability can be detected by radiosonde observations. However, ... -
The Impact of Land Cover Change on a Simulated Storm Event in the Sydney Basin
(American Meteorological Society, 2006)The Regional Atmospheric Modeling System (RAMS) was run at a 1-km grid spacing over the Sydney basin in Australia to assess the impact of land cover change on a simulated storm event. The simulated storm used NCEP?NCAR ... -
Modeling of the Coastal Boundary Layer and Pollutant Transport in New England
(American Meteorological Society, 2006)Concentrations of ozone exceeding regulatory standards are regularly observed along the coasts of New Hampshire and Maine in summer. These events are primarily caused by the transport of pollutants from urban areas in ... -
Relationship between Air Pollution in Hong Kong and in the Pearl River Delta Region of South China in 2003 and 2004: An Analysis
(American Meteorological Society, 2006)Air pollution in the Pearl River Delta (PRD) region of south China, which is one of the four regions in China most heavily affected by haze, is found to correlate with that of Hong Kong, indicating the regional nature of ... -
On the Influence of Assumed Drop Size Distribution Form on Radar-Retrieved Thunderstorm Microphysics
(American Meteorological Society, 2006)Polarimetric radar measurements are used to retrieve drop size distributions (DSD) in subtropical thunderstorms. Retrievals are made with the single-moment exponential drop size model of Marshall and Palmer driven by radar ... -
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 ... -
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 ... -
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 ... -
Rainfall Climate Regimes: The Relationship of Regional TRMM Rainfall Biases to the Environment
(American Meteorological Society, 2006)Intercomparisons of satellite rainfall products have historically focused on the issue of global mean biases. Regional and temporal variations in these biases, however, are equally important for many climate applications. ... -
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 I: Liquid Clouds
(American Meteorological Society, 2006)The importance of accurately representing the role of clouds in climate change studies has become increasingly apparent in recent years, leading to a substantial increase in the number of satellite sensors and associated ... -
