Influence of Cloud Condensation Nuclei on Orographic Snowfall
(American Meteorological Society, 2009)Pollution aerosols acting as cloud condensation nuclei (CCN) have the potential to alter warm rain clouds via the aerosol first and second indirect effects in which they modify the cloud droplet population, cloud lifetime ... -
Evaluations of BDA Scheme Using the Advanced Research WRF (ARW) Model
(American Meteorological Society, 2009)A tropical cyclone bogus data assimilation (BDA) scheme is built in the Weather Research and Forecasting three-dimensional variational data assimilation system (WRF 3D-VAR). Experiments were conducted (21 experiments with ... -
Summer Moisture and Wildfire Risks across Canada
(American Meteorological Society, 2009)The Fire Weather Index System has been in use across Canada for the past 30 years in the daily operations of fire management agencies. As part of this system, the Drought Code (DC) was developed to act as a daily index of ... -
Bollène-2002 Experiment: Radar Quantitative Precipitation Estimation in the Cévennes–Vivarais Region, France
(American Meteorological Society, 2009)The Bollène-2002 Experiment was aimed at developing the use of a radar volume-scanning strategy for conducting radar rainfall estimations in the mountainous regions of France. A developmental radar processing system, called ... -
Trends in Extreme Temperatures in Relation to Urbanization in the Twin Cities Metropolitan Area, Minnesota
(American Meteorological Society, 2009)The long-term trends in extreme summer season temperatures across the Twin Cities Metropolitan Area (TCMA) associated with urbanization are examined. To assess trends in extreme temperature data, maximum and minimum ... -
Spatiotemporal Mapping of Temperature and Precipitation for the Development of a Multidecadal Climatic Dataset for Wisconsin
(American Meteorological Society, 2009)Results from the generation of a multidecadal gridded climatic dataset for 57 yr (1950?2006) of daily and monthly precipitation (PTotal), maximum temperature (Tmax), and minimum temperature (Tmin) are presented for the ... -
The CM-SAF and FUB Cloud Detection Schemes for SEVIRI: Validation with Synoptic Data and Initial Comparison with MODIS and CALIPSO
(American Meteorological Society, 2009)The Satellite Application Facility on Climate Monitoring (CM-SAF) is aiming to retrieve satellite-derived geophysical parameters suitable for climate monitoring. CM-SAF started routine operations in early 2007 and provides ... -
The Application of an Evolutionary Algorithm to the Optimization of a Mesoscale Meteorological Model
(American Meteorological Society, 2009)It is shown that a simple evolutionary algorithm can optimize a set of mesoscale atmospheric model parameters with respect to agreement between the mesoscale simulation and a limited set of synthetic observations. This is ... -
Development and Testing of Canada-Wide Interpolated Spatial Models of Daily Minimum–Maximum Temperature and Precipitation for 1961–2003
(American Meteorological Society, 2009)The application of trivariate thin-plate smoothing splines to the interpolation of daily weather data is investigated. The method was used to develop spatial models of daily minimum and maximum temperature and daily ... -
Validation of TRMM Precipitation Radar through Comparison of Its Multiyear Measurements with Ground-Based Radar
(American Meteorological Society, 2009)A procedure to accurately resample spaceborne and ground-based radar data is described and then is applied to the measurements taken from the Tropical Rainfall Measuring Mission (TRMM) precipitation radar (PR) and the ... -
Evaluation of a Satellite Multispectral VIS–IR Daytime Statistical Rain-Rate Classifier and Comparison with Passive Microwave Rainfall Estimates
(American Meteorological Society, 2009)A daytime surface rain-rate classifier, based on artificial neural networks (ANNs), is proposed for the Spinning Enhanced Visible and Infrared Imager (SEVIRI) on board the Meteosat-8 geostationary satellite. It is developed ... -

Sudden Nocturnal Warming Events in Mississippi
(American Meteorological Society, 2009)Significant episodes of sudden nocturnal warming have been observed by the Mississippi Mesonet. The probable relation of these nocturnal warming events to surface layer regime transitions between a decoupled quiescent ... -
A 5-yr 40-km-Resolution Global Climatology of Superrefraction for Ground-Based Weather Radars
(American Meteorological Society, 2009)The propagation of electromagnetic waves emitted from ground-based meteorological radars is determined by the stratification of the atmosphere. In extreme superrefractive situations characterized by strong temperature ... -
Development of a Zero-Dimensional Mesoscale Thermal Model for Urban Climate
(American Meteorological Society, 2009)A simple energy balance model is created for use in developing mitigation strategies for the urban heat island effect. The model is initially applied to the city of Phoenix, Arizona. There are six primary contributions to ... -
Maximum Covariance Analysis of Typhoon Surface Wind and Rainfall Relationships in Taiwan
(American Meteorological Society, 2009)The multivariate relationships between hourly surface wind and rainfall observations during typhoons affecting Taiwan have been investigated with maximum covariance analysis (MCA). Historical surface observations from 1987 ... -
Validation of a Simple Steady-State Forecast of Minimum Nocturnal Temperatures
(American Meteorological Society, 2009)A two-layer steady-state resistance model is compared with routine meteorological data collected from the Western Australian wheat belt during 2000?06. Major difficulties in implementing such a model are the correct ... -
Identifying the Uncertainty in Determining Satellite-Derived Atmospheric Motion Vector Height Attribution
(American Meteorological Society, 2009)This study investigates the assignment of pressure heights to satellite-derived atmospheric motion vectors (AMVs), commonly known as cloud-drift and water vapor?motion winds. Large volumes of multispectral AMV datasets are ... -
Estimation of Daytime Net Radiation from Shortwave Radiation Measurements and Meteorological Observations
