Exploring Regional Emissions and Tropospheric Ozone in the Eastern United States Using Air Quality Models and Data Products
(2019)
Tropospheric ozone (O3) is a harmful pollutant regulated by the US Environmental Protection Agency (EPA) through the use of designated air quality standards. Within the United States, approximately 110 million people live ...
ON THE ORIGIN OF HYDROCLIMATE CHANGE OVER CONTINENTS THROUGH SEASONALLY-STRATIFIED TRENDS
(2019)
Global hydroclimate has undergone significant changes over the twentieth century. Temperature and precipitation changes have not been uniform in space or time and mechanisms driving many continental changes remain to be ...
Data Driven Prediction Without a Model
(2019)
Ensemble data assimilation techniques, including the Ensemble Transform Kalman Filter (ETKF), have been successfully used to improve prediction skill in numerical models for weather forecasting. However, less research has ...
ESTIMATION AND ADAPTIVE ONLINE CORRECTION OF SYSTEMATIC ERRORS IN THE GLOBAL FORECAST SYSTEM (GFS) USING ANALYSIS INCREMENTS
(2019)
Numerical Weather prediction models have improved drastically in the last few decades with advances in data assimilation, improved parameterization, and ensemble forecasting. Despite these developments, the performance of ...
Improving our Understanding of Tropical Cyclone Unusual Motion and Rapid Intensification
(2019)
Despite steady improvement in their tropical cyclone (TC) track and intensity forecasts over recent decades, operational numerical weather prediction (NWP) models still struggle at times in predicting two TC phenomena: ...
Covariance Localization in Strongly Coupled Data Assimilation
(2019)
The recent development of accurate coupled models of the Earth system and enhanced computation power have enabled numerical prediction with the coupled models in weather, sub-seasonal, seasonal, and interannual time scales ...
SEA-SURFACE TEMPERATURE BASED STATISTICAL PREDICTION OF THE SOUTH ASIAN SUMMER MONSOON RAINFALL DISTRIBUTION
(2019)
The South Asian summer monsoon brings copious amounts of rainfall accounting for over 70% of the annual rainfall over India. Summer monsoon predictions have drawn considerable public/policy attention lately as South Asia ...
IMPROVING U.S. EXTREME PRECIPITATION PREDICTION AND PROCESS UNDERSTANDING USING A MESOSCALE CLIMATE MODEL MULTI-PHYSICS ENSEMBLE APPROACH
(2019)
Despite many recent improvements, climate models continue to poorly simulate extreme precipitation. I attempted to improve prediction of extreme precipitation, focusing on daily 95th percentile (P95) events, and to better ...
THE DIURNAL AND SEASONAL RADIATIVE EFFECTS OF CIRRUS CLOUDS UTILIZING LARGE AIRBORNE AND SPACE-BORNE LIDAR DATASETS
(2019)
Cirrus clouds are globally the most common cloud type, however, their
radiative impact on the Earth remains a large source of uncertainty in global climate
models. Cirrus are unique in that they are absorptive to terrestrial ...
Socioeconomic and Climate Impacts on the Future of Water: An Integrated Assessment Approach to Demand, Scarcity, and Trade
(2019)
Changes to socioeconomics and an evolving climate system are likely to play a vital role in how regions around the world use water into the future. Water projections for the future, while prolific, remain highly variable ...
