Integrated kinetic energy (IKE) is a recently developed metric that approximates the destructive potential of a tropical cyclone by assessing the size and strength of its wind field. Despite the potential usefulness of the IKE metric, ...
The advancement of numerical weather prediction (NWP) has hastened the effort to understand how moist processes -- many of which are parameterized in NWP models -- influence cyclone structure and intensity. Despite this effort, there...
Rossby waves are waves in potential vorticity that propagate along the extratropical tropopause and can be impacted by the advection of low-PV air originating from the subtropics. In this study, the subtropical precipitation influence on...
This study develops nudging methods of data assimilation that will expand the utility of the forthcoming GOES-R satellite series by including data from the Geostationary Lightning Mapper (GLM) and Advanced Baseline Imager (ABI). We...
Deep convection is an important component of atmospheric circulations that affects many aspects of weather and climate. Therefore, improved understanding and realistic simulations of deep convection are critical to both operational and...
Wave and wind direction effects on remote sensing measurements of ocean surface emissivity are investigated using a microwave radiometer in high wind conditions with a focus on tropical cyclones. Surface wind speed, which drives many...
Disorganized, weakly forced convection is a routine summertime occurrence in the Southeast United States. Pulse severe storms are single cell thunderstorms that produce severe wind and/or severe hail for a brief period of time. These...
A comprehensive rainfall-based index of the Australian monsoon is created. This index is based on methodology previously used on the Indian subcontinent for determining the seasonality of the Indian monsoon. In order to create the...
This analysis investigates the relationship between Rossby wave breaking (RWB) and tropical cyclone (TC) activity on a variety of timescales in the northern hemisphere (NH). This will be done through a time series analysis between wave...
Vertical profiles of wind, potential temperature, and humidity within hurricanes are shown to exhibit approximately log-linear behavior within the near-surface layer and can therefore be used to estimate log-profile parameters in such an...
Atmospheric water vapor is a potent greenhouse gas, and its variations in the upper troposphere and lower stratosphere (UTLS) have important climate impacts. The water vapor budget of tropical cyclones (TCs) and their impact on the UTLS...
The atmospheric response to one-way coupled ocean surface currents is examined in this study through the use of merged ocean surface currents from NASA Doppler scatterometer data and Hybrid Coordinate Ocean Model (HYCOM) data in the...
The impact of including Sea Surface Temperatures (SSTs) of differing horizontal grid spacings in simulations of river and sea breeze related weather has not been studied extensively in the Cape Canaveral area of Florida. This study...
Central America exhibits a distinct seasonal cycle of rainfall, which is objectively defined in this study as having an onset date and a demise date of the wet season on the first and the last day of the year when its daily rainfall...
Each year, tropical cyclones (TCs) impact communities around the world by producing rainfall with devastating damage, loss of life and can contribute a non-trivial amount to climatological annual mean rainfall. The representation of TC...
Global models have certain biases that are not yet fully understood. Since they are used to representtropical cyclones (TCs), we need to have a solid understanding of these biases in order to accurately study TCs. The motivation behind...
This research focuses on the transport of chemical species to the upper troposphere/lower stratosphere (UTLS) by tropical cyclones (TCs). Species such as carbon monoxide, nitrogen oxides, and ozone have been found to exert a greater...
Mexico and Central America (Mesoamerica) are situated in a complex and unique geographical position with the Caribbean Sea to the East and the tropical Eastern Pacific Ocean to the West. The weather patterns of this region are driven by...
Interactions between clouds, water vapor, radiation, and circulation influence the organization of tropical convection, and the development of tropical cyclones (TCs). This includes the self-aggregation (SA) of convection in idealized...
Atmospheric fronts are responsible for changes in temperature, precipitation, and wind direction, and are often associated with extremes related to the weather, such as cold snaps and flooding, that have significant socio-economic...
The high frequency of cyclogenesis in the northwestern Gulf of Mexico is often attributed to warm sea surface temperature. In this thesis, the importance of surface fluxes were documented to understand the air-sea interaction effect on...
A new methodology has been introduced to detect flash droughts. This method is based off a new variable created called the drought index. This index is calculated using the cumulative daily anomalies of soil moisture, precipitation, and...
At the polar latitudes, maritime mesocyclones form throughout the year, often near or embedded within cloud streets associated with massive cold air outbreaks. Such storms appear on the 100–1000 km horizontal scale. However, polar...
This study explores whether or not tropical cyclone (TC) structure information may be retrieved from satellite total ozone observations and how to link total ozone with analysis fields for potential application to TC vortex...
This study provides, to our knowledge, the first detailed analysis of how oil changes air-sea interaction in a two-way coupled model (COAWST), and how the modified surface stress and surface Ekman current change the transport of the oil....
Florida, in the southeast US, is vulnerable to heatwaves due to its unique geolocation, exacerbated by both high temperature and humidity. To better understand the future impact on heatwave events over Florida we first conduct a...
The rapid development and sub-synoptic scale nature of the Genoa low in the Mediterranean Sea poses a forecasting challenge for United States Air Force (USAF). The Genoa low is a high-impact event for several Department of Defense (DOD)...
Prescribed burning is a land management technique conducted at Eglin Air Force Base (AFB), Florida (FL), by Jackson Guard. Sometimes a fire-induced cumulus cloud, called a pyrocumulus (pyroCu), forms over a surface fire. A towering...
A simplified model of the Great Plains Nocturnal Low-level Jet (NLLJ) is formulated to include the classical inertial oscillation (Blackadar) and baroclinic (Holton) mechanisms. Time and height dependent solutions are analytically...
Severe weather indices are empirical tools developed by meteorologists to assist in predicting severe weather. The Storm Prediction Center’s (SPC) Mesoanalysis website lists 23 composite indices. All of the listed composite indices are...
This study investigates the response of the extratropical jet to recurving North Atlantic tropical cyclones (TCs). A joint climatology of north Atlantic recurving TCs from 2007-2013 and Rossby waves on the extratropical jet is presented....
Wave-driven transport, also known as Stokes drift, is the motion of a particle due to the orbital motion induced by a passing wave. This orbital motion does not form closed loops, leading to a net displacement over a single wave period....
Rossby waves propagating along the extratropical tropopause have a dominant impact on weather at the surface in midlatitudes via baroclinic instability. While forecasts of waves by numerical weather prediction systems are limited by...
Precipitation from atmospheric fronts accounts for a significant portion of the total precipitation in the mid-latitudes, with some locations receiving the majority of their precipitation from atmospheric fronts. In addition, a...
In the United States, tropical cyclones (TCs) were the leading cause of natural disaster-related fatalities and Consumer Price Index (CPI)-adjusted costs averaged over the years 1980-2017. Accurately assessing TC-induced extreme winds is...
