Reliability and Climatological Impacts of Convective Wind Estimations
(American Meteorological Society, 2018)AbstractConvective surface winds in the contiguous United States are classified as severe at 50 kt (58 mi h?1, or 26 m s?1), whether measured or estimated. In 2006, NCDC (now NCEI) Storm Data, from which analyzed data are ... -
Surface-Based Microwave Humidity Retrievals over the Equatorial Indian Ocean: Applications and Challenges
(American Meteorological Society, 2018)AbstractThe interactions between equatorial convection and humidity as a function of height, at a range of time scales, remain an important research frontier. The ability of surface-based microwave radiometry to contribute ... -
Sources of Bias in the Monthly CFSv2 Forecast Climatology
(American Meteorological Society, 2018)AbstractForecast climatologies are used to remove systematic errors from forecasts and to express forecasts as departures from normal. Forecast climatologies are computed from hindcasts by various averaging, smoothing, and ... -
Characterizing the Atmospheric Conditions Leading to Large Error Growth in Volcanic Ash Cloud Forecasts
(American Meteorological Society, 2018)ABSTRACTVolcanic ash poses an ongoing risk to safety in the airspace worldwide. The accuracy with which volcanic ash dispersion can be forecast depends on the conditions of the atmosphere into which it is emitted. In this ... -
Great Lakes Basin Snow-Cover Ablation and Synoptic-Scale Circulation
(American Meteorological Society, 2018)AbstractSynoptic-scale atmospheric conditions play a critical role in determining the frequency and intensity of snow-cover-ablation events. Using a synoptic weather-classification technique, distinct regional circulation ... -
A Method for Identifying Midlatitude Mesoscale Convective Systems in Radar Mosaics. Part II: Tracking
(American Meteorological Society, 2018)AbstractThis research is Part II of a two-part study that evaluates the ability of image-processing and select machine-learning algorithms to detect, classify, and track midlatitude mesoscale convective systems (MCSs) in ... -
A Method for Identifying Midlatitude Mesoscale Convective Systems in Radar Mosaics. Part I: Segmentation and Classification
(American Meteorological Society, 2018)AbstractThis research evaluates the ability of image-processing and select machine-learning algorithms to identify midlatitude mesoscale convective systems (MCSs) in radar-reflectivity images for the conterminous United ... -
Ambient Factors Controlling the Wintertime Precipitation Distribution Across Mountain Ranges in the Interior Western United States. Part I: Insights from Regional Climate Simulations
(American Meteorological Society, 2018)AbstractThis study analyzes the control of upstream conditions on the distribution of wintertime precipitation across mountain ranges in the interior western United States using 10 winters of high-resolution regional climate ... -
Observational Constraint for Precipitation in Extratropical Cyclones: Sensitivity to Data Sources
(American Meteorological Society, 2018)AbstractUsing cyclone-centered compositing and a database of extratropical-cyclone locations, the distribution of precipitation frequency and rate in oceanic extratropical cyclones is analyzed using satellite-derived ... -
Comparison of Linear Predictability of Surface Wind Components from Observations with Simulations from RCMs and Reanalysis
(American Meteorological Society, 2018)AbstractThis study compares the predictability of surface wind components by linear statistical downscaling using data from both observations and comprehensive models [regional climate models (RCM) and NCEP-2 reanalysis] ... -
A 0.01° Resolving TRMM PR Precipitation Climatology
(American Meteorological Society, 2018)AbstractIn this study, rainfall data are prepared at a 0.01° scale using 16-yr spaceborne radar data over the area of 36.13°S?36.13°N as provided by the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR). ... -
Assessment of Alaska Rain-on-Snow Events Using Dynamical Downscaling
(American Meteorological Society, 2018)AbstractThe ice formed by cold-season rainfall or rain on snow (ROS) has striking impacts on the economy and ecology of Alaska. An understanding of the atmospheric drivers of ROS events is required to better predict them ... -
NU-WRF Aerosol Transport Simulation over West Africa: Effects of Biomass Burning on Smoke Aerosol Distribution
