Impacts of the Midwestern Drought Forecasts of 2000
(American Meteorological Society, 2002)In March of 2000 (and again in April and May) NOAA issued long-range forecasts indicating that an existing Midwestern drought would continue and intensify through the upcoming summer. These forecasts received extensive ... -
Measurement and Analysis of Puff Dispersion above the Atmospheric Boundary Layer Using Quantitative Imagery
(American Meteorological Society, 2002)Collection and analysis of puff dispersion data in the atmosphere using a remote sensing technique are presented. Quantitative measurements of standard deviation of the concentration distribution in the along-wind and ... -
A Case Study of the Morning Evolution of the Convective Boundary Layer Depth
(American Meteorological Society, 2002)Because of the importance of the convective boundary layer depth (CBLD) in determining pollutant concentrations near the surface, a study of the morning evolution of the convective boundary layer was carried out at the ... -
Principal Component Image Analysis of MODIS for Volcanic Ash. Part I: Most Important Bands and Implications for Future GOES Imagers
(American Meteorological Society, 2002)In Part I of this paper, the infrared bands of the Moderate Resolution Imaging Spectroradiometer (MODIS) are analyzed for volcanic ash signals using principal component image analysis. Target volcanoes included Popocatepetl ... -
Principal Component Image Analysis of MODIS for Volcanic Ash. Part II: Simulation of Current GOES and GOES-M Imagers
(American Meteorological Society, 2002)In Part I of this paper the infrared bands of the Moderate Resolution Imaging Spectroradiometer (MODIS) were analyzed using principal component image analysis for volcanic ash signals. The analyses performed determined ... -
X-Band Polarimetric Radar Measurements of Rainfall
(American Meteorological Society, 2002)A combined polarimetric estimator for rainfall rate (R) retrievals from polarimetric radar measurements at X band is proposed. This estimator uses the horizontal polarization radar reflectivity Ze, differential reflectivity ... -
Mesoscale Wind Regimes in Chile at 30°S
(American Meteorological Society, 2002)In November of 1999, four permanent surface stations were installed in the vicinity of the surface ozone monitoring station on the summit of the Cerro Tololo (2200 m MSL) in Chile at 30°S. These stations were used to study ... -
Simple Modifications to Improve Fifth-Generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model Performance for the Phoenix, Arizona, Metropolitan Area
(American Meteorological Society, 2002)The diurnal temperature cycle in the Phoenix, Arizona, metropolitan area, as represented in the fifth-generation Pennsylvania State University?National Center for Atmospheric Research Mesoscale Model (MM5), is examined ... -
Changes in the Frequency of Extreme Warm-Season Surface Dewpoints in Northeastern Illinois: Implications for Cooling-System Design and Operation
(American Meteorological Society, 2002)Warm-season (1 May?30 September) hourly dewpoint data were examined for temporal changes at two weather stations in northeastern Illinois during a 42-yr period (1959?2000). This area has dense population (greater than 8 ... -
Relationship between the Vertical Velocity Skewness and Kurtosis Observed during Sea-Breeze Convection
(American Meteorological Society, 2002)Fourth-order moments of vertical velocity in the convective boundary layer (CBL) are seldom available because the unsteady nature of atmospheric flows makes time statistics unreliable for the evaluation of high-order ... -
Comments on “A More Extensive Investigation of the Use of Ensemble Forecasts for Dispersion Model Evaluation”

Geostatistical Analyses of Landsat Thematic Mapper–Derived Surface Temperature during Winter Nights
(American Meteorological Society, 2002)Geostatistical analyses were used to clarify the effects of the spatial structure of terrain on the spatial variability of satellite-derived surface temperatures on clear winter nights in central Japan. The clarification ... -
Multiyear Observations of Cloud Lines Associated with the Chesapeake and Delaware Bays
(American Meteorological Society, 2002)Satellite and corresponding near-surface in situ observations have been made of single- and dual-band cloud events [dubbed anomalous cloud lines (ACLs)] associated with the Chesapeake and Delaware Bays. A previous study ... -
Comparison of Rainfall Products Derived from TRMM Microwave Imager and Precipitation Radar
(American Meteorological Society, 2002)Satellite remote sensing is an indispensable means of measuring and monitoring precipitation on a global scale. The Tropical Rainfall Measuring Mission (TRMM) is continuing to make significant progress in helping the global ... -
Monthly Mean Solar Radiative Fluxes and Cloud Forcing over South America in the Period of 1986–88: GCM Results and Satellite-Derived Data
(American Meteorological Society, 2002)The incident solar radiative fluxes, simulated by an atmospheric general circulation model over South America for the period 1986?88, are compared with the satellite-derived surface fluxes provided by the Surface Radiation ... -
Cloud Halos: Numerical Simulation of Dynamical Structure and Radiative Impact
(American Meteorological Society, 2002)Significant enhancements in humidity around cumulus clouds, that is, the ?cloud halos? observed in many aircraft penetrations, are simulated using a three-dimensional dynamic model. Five case studies show that humidity ... -
Air Temperature Model Evaluation in the North Mediterranean Belt Area
