Evaluation of Orographic Cloud Seeding Using a Bin Microphysics Scheme: Three-Dimensional Simulation of Real Cases
(American Meteorological Society, 2020)The University of Pécs and NCAR Bin (UPNB) microphysical scheme was implemented into the mesoscale Weather Research and Forecast (WRF) Model that was used to study the impact of silver iodide (AgI) seeding on precipitation ... -
Major Over- and Underestimation of Drought Found in NOAA’s Climate Divisional SPI Dataset
(American Meteorological Society, 2020)Evaluation of the standardized precipitation index (SPI) dataset published monthly in the National Oceanic and Atmospheric Administration/National Centers for Environmental Information (NOAA/NCEI) climate divisional database ... -
Investigation of a nocturnal cold-air pool in a semi-closed basin located in the Atacama Desert
(American Meteorological Society, 2020)In desert environments, intense radiative cooling of the surface during the night leads to rapid cooling of the adjacent air, resulting in a strong temperature inversion conducive to cold air pool formation. In this work ... -
Evaluating the performance of WRF urban schemes and PBL schemes over Dallas Fort Worth during a dry summer and a wet summer
(American Meteorological Society, 2020)This study evaluated the Weather Research and Forecasting (WRF) model sensitivity to different planetary boundary layer (PBL) schemes (the YSU and MYJ schemes) and urban schemes including the bulk scheme (BULK), single-layer ... -
Geospatial QPE Accuracy Dependence on Weather Radar Network Configurations
(American Meteorological Society, 2020)The relatively low density of weather radar networks can lead to low-altitude coverage gaps. As existing networks are evaluated for gap-fillers and new networks are designed, the benefits of low-altitude coverage must be ... -
The Influences of Urban Building Complexes on the Ambient Flows over the Washington–Reston Region
(American Meteorological Society, 2019)AbstractThis paper examines the collective impacts of urban building complexes on the planetary boundary layer (PBL) winds using both observations and a mesoscale model. Horizontal winds measured on the rooftops of federal ... -
The Influence of Dynamics and Emissions Changes on China’s Wintertime Haze
(American Meteorological Society, 2019)AbstractHaze days induced by aerosol pollution in North and East China have posed a persistent and growing problem over the past few decades. These events are particularly threatening to densely populated cities such as ... -
Estimation of Atlantic Tropical Cyclone Rainfall Frequency in the United States
(American Meteorological Society, 2019)AbstractTropical cyclones pose a significant flood risk to vast land regions in their path because of extreme precipitation. Thus it is imperative to quantitatively assess this risk. This study compares exceedance frequencies ... -
Impacts of Climate Warming on Aviation Fuel Consumption
(American Meteorological Society, 2019)AbstractFactors affecting aviation fuel efficiency are thermal and propulsive efficiencies, and overall drag on aircraft. An along-the-route integration is made for all direct flights in a baseline year, 2010, under current ... -
Impacts of Small-Scale Urban Encroachment on Air Temperature Observations
(American Meteorological Society, 2019)AbstractA field experiment was performed in Oak Ridge, Tennessee, with four instrumented towers placed over grass at increasing distances (4, 30, 50, 124, and 300 m) from a built-up area. Stations were aligned in such a ... -
Use of High-Resolution Numerical Models and Statistical Approaches to Understand New Zealand Historical Wind Speed and Gust Climatologies
(American Meteorological Society, 2019)AbstractThis paper describes how a combination of high-resolution numerical modeling, a robust homogenization algorithm, and local pressure observations have been used to understand and reconcile time series of daily, ... -
A New Method to Diagnose Cyclone–Cyclone Interaction and Its Influences on Precipitation
(American Meteorological Society, 2019)AbstractUnlike the classical point vortex model, a new method is developed to extract flows induced not only by vorticity but also by divergence in a well-defined vortex core area of a cyclone. This new method is applied ... -
Estimation of Melting-Layer Cooling Rate from Dual-Polarization Radar: Spectral Bin Model Simulations
(American Meteorological Society, 2019)AbstractDiabatic cooling from hydrometeor phase changes in the stratiform melting layer is of great interest to both operational forecasters and modelers for its societal and dynamical consequences. Attempts to estimate ... -
Changing Spatiotemporal Patterns of 5- and 10-Day Illinois Heavy Precipitation Amounts, 1900–2018
(American Meteorological Society, 2019)AbstractThis study examined the spatiotemporal variability associated with 5-/10-day heavy precipitation amounts for 48 high-quality and long-duration (1900?2018) stations in Illinois. The top five seasonal and annual heavy ... -
Environmental Covariate Representation of Seasonal U.S. Tornado Frequency
(American Meteorological Society, 2019)AbstractThe significant tornado parameter is a widely used meteorological composite index that combines several variables known to favor tornadic supercell thunderstorms. This research examines the spatial relationship ... -
Trends in Instrument Flight Rules (IFR) Conditions at Major Airports in the United States
(American Meteorological Society, 2019)AbstractWeather-related delays are among the most common in aviation and are frequently the result of low visibility or cloud ceilings, which cause landing aircraft to be spaced farther apart for safety, reducing the ... -
The Fall Speed Variability of Similarly Sized Ice Particle Aggregates
(American Meteorological Society, 2019)AbstractThe terminal velocity (Vt) of ice hydrometeors is of high importance to atmospheric modeling. Vt is governed by the physical characteristics of a hydrometeor, including mass and projected area, as well as environmental ... -
Development of Near-Cloud Turbulence Diagnostics Based on a Convective Gravity Wave Drag Parameterization
(American Meteorological Society, 2019)AbstractWe propose near-cloud turbulence (NCT) diagnostics for use in aviation turbulence forecasting, using a convective gravity wave drag (CGWD) parameterization scheme. The NCT diagnostics are obtained based on (i) CGWD ... -
