Meteorological Impacts on Commercial Aviation Delays and Cancellations in the Continental United States
(American Meteorological Society, 2019)AbstractWeather creates numerous operational and safety hazards within the National Airspace System (NAS). In 2014, extreme weather events attributed 4.3% to the total number of delay minutes recorded by the Bureau of ... -
Synoptic to Microscale Processes Affecting the Evolution of a Cold-Air Pool in a Northern New England Forested Mountain Valley
(American Meteorological Society, 2019)AbstractThe formation of katabatic winds and pooling of cold air in mountain valleys impact air quality, precipitation type, and local ecosystem functions. Much is still poorly understood about the multiscale interaction ... -
Observations of Thermally Driven Circulations in the Pyrenees: Comparison of Detection Methods and Impact on Atmospheric Composition Measured at a Mountaintop
(American Meteorological Society, 2019)AbstractThe atmospheric composition measured at the Pic du Midi high-altitude observatory (2875 m MSL) in the French Pyrenees is frequently affected by upward transport of boundary layer air during anabatic circulations ... -
Reconstructing the Drizzle Mode of the Raindrop Size Distribution Using Double-Moment Normalization
(American Meteorological Society, 2018)Commonly used disdrometers tend not to accurately measure concentrations of very small drops in the raindrop size distribution (DSD), either through truncation of the DSD at the small-drop end or because of large uncertainties ... -
Gamma Drop Size Distribution Assumptions in Bulk Model Parameterizations and Radar Polarimetry and Their Impact on Polarimetric Radar Moments
(American Meteorological Society, 2019)A suitable formulation of the rain drop size distribution (DSD) is a prerequisite for a successful assimilation of radar polarimetric information on rain into a numerical weather prediction model. Popular DSD parameterizations ... -
An Analysis of the Reliability of a New Dataset of Transmission Line Icing Thickness in Southern China
(American Meteorological Society, 2019)Based on ERA-Interim data, gauge observations, transmission line icing observational data, and hindcasted predictors from a numerical forecast system of transmission line icing, a new transmission line icing thickness ... -
Gaussian Copula Method for Bias Correction of Daily Precipitation Generated by a Dynamical Model
(American Meteorological Society, 2018)The daily precipitation data generated by dynamical models, including regional climate models, generally suffer from biases in distribution and spatial dependence. These are serious flaws if the data are intended to be ... -
Incorporating the Work Done by Vertical Density Fluxes in Both Kinetic and Thermal Energy Conservation Equations to Satisfy Total Energy Conservation
(American Meteorological Society, 2018)Conservation of total, kinetic, and thermal energy in the atmosphere is revisited, and the derived thermal energy balance is examined with observations. Total energy conservation (TEC) provides a constraint for the sum of ... -
Assessing Wind Data from Reanalyses for the Upper Midwest
(American Meteorological Society, 2019)Wind is an important atmospheric variable that is receiving increased attention as the world seeks to shift from carbon-based fuels in order to mitigate climate change. This has resulted in increased need for more temporally ... -
Observed Rainfall Trends over Singapore and the Maritime Continent from the Perspective of Regional-Scale Weather Regimes
(American Meteorological Society, 2018)Straddling the Asian?Australian monsoon region, the Maritime Continent (MC) experiences substantial rainfall variations from diurnal to interannual and longer time scales. In this study, rainfall over Singapore and the ... -
Dissipation Characteristics of Tornadic Vortex Signatures Associated with Long-Duration Tornadoes
(American Meteorological Society, 2018)Weather Surveillance Radar?1988 Doppler (WSR-88D) data from 36 tornadic supercell cases from 2012 to 2016 are investigated to identify common tornadic vortex signature (TVS) behaviors prior to tornado dissipation. Based ... -
The RheaG Weather Generator Algorithm: Evaluation in Four Contrasting Climates from the Iberian Peninsula
(American Meteorological Society, 2018)This paper describes the assumptions, equations, and procedures of the RheaG weather generator algorithm (WGA). RheaG was conceived for the generation of robust daily meteorological time series, whether in static or transient ... -
A New Method to Characterize Changes in the Seasonal Cycle of Snowpack
(American Meteorological Society, 2018)In the western United States, water stored as mountain snowpack is a large percentage of the total water needed to meet the region?s demands, and it is likely that, as the planet continues to warm, mountain snowpack will ... -
Comparisons of Electromagnetic Scattering Properties of Real Hailstones and Spheroids
(American Meteorological Society, 2018)Severe (>2.5 cm) hail causes >$5 billion in damage annually in the United States. However, radar sizing of hail remains challenging. Typically, spheroids are used to represent hailstones in radar forward operators and to ... -
Normalized Hail Particle Size Distributions from the T-28 Storm-Penetrating Aircraft
(American Meteorological Society, 2018)Hail and graupel are linked to lightning production and are important components of cloud evolution. Hail can also cause significant damage when it precipitates to the surface. The accurate prediction of the amount and ... -
A Moment-Based Polarimetric Radar Forward Operator for Rain Microphysics
(American Meteorological Society, 2018)There is growing interest in combining microphysical models and polarimetric radar observations to improve our understanding of storms and precipitation. Mapping model-predicted variables into the radar observational space ... -
A General N-Moment Normalization Method for Deriving Raindrop Size Distribution Scaling Relationships
(American Meteorological Society, 2018)A general drop size distribution (DSD) normalization method is formulated in terms of generalized power series relating any DSD moment to any number and combination of reference moments. This provides a consistent framework ... -
