Evaluation of Interregional Transport Using the MM5–SCIPUFF System
(American Meteorological Society, 2004)Improved understanding of transport issues and source?receptor relationships on the interregional scale is dependent on reducing the uncertainties in the ability to define complex three-dimensional wind fields evolving in ... -
Retrieving Stratocumulus Drizzle Parameters Using Doppler Radar and Lidar
(American Meteorological Society, 2005)Stratocumulus is one of the most common cloud types globally, with a profound effect on the earth?s radiation budget, and the drizzle process is fundamental in understanding the evolution of these boundary layer clouds. ... -
Katabatic Flow Mechanisms on a Low-Angle Slope
(American Meteorological Society, 2005)Momentum and heat budget equations for katabatic flows on sloping surfaces are revisited. Terms in these equations are evaluated using wind and potential temperature data from four tethered-balloon data collection systems ... -
Evening Transition Observations in Phoenix, Arizona
(American Meteorological Society, 2005)Past research has suggested that the evening transition in complex topography typically has several main features, such as (a) continued weak upslope flows persisting 3?5 h after sunset (if the sidewalls of the valley ... -
An Application of the Variational Method to Computation of Sensible Heat Flux over a Deciduous Forest
(American Meteorological Society, 2005)A variational method is employed to compute surface sensible heat fluxes over a deciduous forest using observed temperature, temperature variance, and wind. Because the variational approach is able to take into account ... -
Variability of Drop Size Distributions: Time-Scale Dependence of the Variability and Its Effects on Rain Estimation
(American Meteorological Society, 2005)A systematic and intensive analysis is performed on 5 yr of reliable disdrometric data (over 20 000 one-minute drop size distributions, DSDs) to investigate the variability of DSDs in the Montreal, Quebec, Canada, area. ... -
Precipitation Estimation from Remotely Sensed Imagery Using an Artificial Neural Network Cloud Classification System
(American Meteorological Society, 2004)A satellite-based rainfall estimation algorithm, Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN) Cloud Classification System (CCS), is described. This algorithm extracts ... -
The Role of Airmass Types and Surface Energy Fluxes in Snow Cover Ablation in the Central Appalachians
(American Meteorological Society, 2004)A one-dimensional snowpack model, a unique airmass identification scheme, and surface weather observations are used to investigate large ablation events in the central Appalachian Mountains of North America. Data from ... -
Pseudovertical Temperature Profiles and the Urban Heat Island Measured by a Temperature Datalogger Network in Phoenix, Arizona
(American Meteorological Society, 2005)As part of an air-quality field campaign conducted in Phoenix, Arizona, during the summer of 2001, a network of temperature dataloggers and surface meteorological stations was deployed across the metropolitan area for a ... -
Water Vapor Exchange between Soil and Atmosphere over a Gobi Surface near an Oasis in the Summer
(American Meteorological Society, 2004)Using data observed at Dunhuang, in the Gansu, in the arid region of northwest China in the summer, the characteristics of the soil water content, temperature, and atmospheric humidity were analyzed. It was found that the ... -
Comparison of Numerical Methods for Computing Radiative Temperature Changes in the Atmospheric Boundary Layer
(American Meteorological Society, 1966)Three models, based on methods of Brooks and Elsasser, and on transmission functions of Davis and Viezee, are used to compute the infrared surface flux and the flux divergence in the lower atmosphere. The three models are ... -
Estimating Overwater Turbulence Intensity from Routine Gust-Factor Measurements
(American Meteorological Society, 2004)For overwater diffusion estimates the Offshore and Coastal Dispersion (OCD) model is preferred by the U.S. Environmental Protection Agency. The U.S. Minerals Management Service has recommended that the OCD model be used ... -
Remote Cloud Ceiling Assessment Using Data-Mining Methods
(American Meteorological Society, 2004)Data-mining methods are applied to numerical weather prediction (NWP) output and satellite data to develop automated algorithms for the diagnosis of cloud ceiling height in regions where no local observations are available ... -
Background Error Correlation between Surface Skin and Air Temperatures: Estimation and Impact on the Assimilation of Infrared Window Radiances
(American Meteorological Society, 2004)This paper makes use of ensemble forecasts to infer the correlation between surface skin temperature Ts and air temperature Ta model errors. The impact of this correlation in data assimilation is then investigated. In the ... -
