(American Meteorological Society, 2013)his research compares reanalysis-derived proxy soundings from the North American Regional Reanalysis (NARR) with collocated observed radiosonde data across the central and eastern United States during the period 2000?11: ... -
Diagnosing the Intercept Parameters of the Exponential Drop Size Distributions in a Single-Moment Microphysics Scheme and Impact on Supercell Storm Simulations
(American Meteorological Society, 2014)n this study, power-law relations are developed between the intercept parameter N0 of the exponential particle size distribution and the water content for the rain, hail, graupel, and snow hydrometeor categories within the ... -
Use of Radar Chaff for Studying Circulations in and around Shallow Cumulus Clouds
(American Meteorological Society, 2014)irculations in and around cumulus clouds are inferred by using a passive tracer (radar chaff) and an airborne cloud radar during the Barbados Aerosol Cloud Experiment (BACEX). The radar chaff elements used for this experiment ... -
Uncertainty in Contaminant Concentration Fields Resulting from Atmospheric Boundary Layer Depth Uncertainty
(American Meteorological Society, 2014)he relationship between atmospheric boundary layer (ABL) depth uncertainty and uncertainty in atmospheric transport and dispersion (ATD) simulations is investigated by examining profiles of predicted concentrations of a ... -
Performance of Alternative “Normals” for Tracking Climate Changes, Using Homogenized and Nonhomogenized Seasonal U.S. Surface Temperatures
(American Meteorological Society, 2013)leven alternatives to the annually updated 30-yr average for specifying climate ?normals? are considered for the purpose of projecting nonstationarity in the mean U.S. temperature climate during 2006?12. Comparisons are ... -
Improved Historical Temperature and Precipitation Time Series for U.S. Climate Divisions
(American Meteorological Society, 2014)his paper describes an improved edition of the climate division dataset for the conterminous United States (i.e., version 2). The first improvement is to the input data, which now include additional station networks, quality ... -
Cyclone Wind Field Asymmetries during Extratropical Transition in the Western North Pacific
(American Meteorological Society, 2013)isk-assessment systems for wind hazards (e.g., hurricanes or typhoons) often rely on simple parametric wind field formulations. They are built using extensive observations of tropical cyclones and make assumptions about ... -
Assessing Impacts of Integrating MODIS Vegetation Data in the Weather Research and Forecasting (WRF) Model Coupled to Two Different Canopy-Resistance Approaches
(American Meteorological Society, 2014)he impact of 8-day-averaged data from the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor?namely, the 1-km leaf area index, absorbed photosynthetic radiation, and land-use data?is investigated for use in the ... -
Late Winter Sea Ice in the Bering Sea: Predictor for Maize and Rice Production in Northeast China
(American Meteorological Society, 2014)n this research, the linkage between late winter Bering Sea ice and maize/rice yields in northeastern China (NEC) is investigated. Results show that such ice influences NEC crop production and thus can be employed to predict ... -
Comments on “Effect of Electric Charge on Collisions between Cloud Droplets”
(American Meteorological Society, 2014)letcher?s simple model for the electric force between charged conducting spheres (with reference to cloud droplets) is compared with an exact model and also with another approximate model. His results for the charge ratio ... -
The Dispersion of Silver Iodide Particles from Ground-Based Generators over Complex Terrain. Part II: WRF Large-Eddy Simulations versus Observations
