Climatological Analysis Of Tropical Cyclone Occurrence Dates And Landfall Characteristics In The North Atlantic And Eastern North Pacific, Nicholas Sava Grondin
Climatological Analysis Of Tropical Cyclone Occurrence Dates And Landfall Characteristics In The North Atlantic And Eastern North Pacific, Nicholas Sava Grondin
Doctoral Dissertations
Tropical cyclones (TCs) are significant hazards to coastal and inland regions across the globe, especially in North America. North America is affected by TCs from two basins, the North Atlantic (NATL) and eastern North Pacific (ENP), with the former being the predominate focus of past research. In this dissertation, I present three studies that directly compare TCs in the NATL and ENP by using the same methods for each basin in studying occurrence dates and intraseasonal variability, effects of environmental parameters on occurrence dates and seasonal forecasting, and the behavior of TCs during the final 36 hours before landfall in …
Convection Allowing Simulations Of Hail In Historical And Future Climate Epochs, Jillian Rose Goodin
Convection Allowing Simulations Of Hail In Historical And Future Climate Epochs, Jillian Rose Goodin
Graduate Research Theses & Dissertations
This thesis investigates the potential impact of anthropogenic climate change on hail frequency and intensity, which poses a significant threat to life and property, accounting for annual insured losses of around $30 billion in the U.S. This approach uses convection-allowing dynamically-downscaled regional climate simulations using input data from NCAR's bias-corrected Community Earth System Model to simulate historical and projected future climate regimes under two greenhouse gas emission scenarios. A column maximum diameter hail diagnostic is simulated by the Weather Research and Forecasting regional climate model to identify instances of hail days and size to quantify changes in large hail frequency …
Climatology Of The Elevated Mixed Layer Over The Contiguous United States And Northern Mexico: 1979–2021, Margo Siciliano Andrews
Climatology Of The Elevated Mixed Layer Over The Contiguous United States And Northern Mexico: 1979–2021, Margo Siciliano Andrews
Graduate Research Theses & Dissertations
Elevated mixed layers (EMLs) are an important influence on the severe convective storm climatology in the contiguous United States (CONUS), playing a role in storm generation, sustenance, and suppression. A function of the topography in the western CONUS and northern Mexico, EMLs are elevated layers of nearly dry adiabatic lapse rates and high potential temperature, typically with a capping inversion at their base. Although it is well-established that EMLs are primarily a warm-season phenomenon most frequent in the Great Plains, no research to date has examined their variability in-depth, or whether they have changed through time. This study creates an …
Nashville-Basin Tornadoes: Using Storm Types To Elucidate The Local Climatology And Forecasting Challenges, Morgan Steckler, Kelsey Ellis
Nashville-Basin Tornadoes: Using Storm Types To Elucidate The Local Climatology And Forecasting Challenges, Morgan Steckler, Kelsey Ellis
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
Early 3 March 2020 was a devastating night for many middle Tennessee residents. A strong EF-3 tornado tore through Nashville at 65 mph, and another EF-4 killed 18 in Baxter and Cookeville alone. Residents of the Southeastern United States are particularly vulnerable to tornadoes. This study aims to better understand local forecasting challenges by looking at the types of storms that produce tornadoes. Storm types, also known as convective modes, divide tornado-producing storms into categories by length, shape, multiplicity, and intensity. Distinguishing storms by these modes allows for a broader understanding of their occurrences and impacts. This study specifically evaluates …
A Mesonet-Based Analysis Of Severe Convective Winds In West Texas., Quint Long
A Mesonet-Based Analysis Of Severe Convective Winds In West Texas., Quint Long
Electronic Theses and Dissertations
Multiple studies have investigated the occurrence of severe convective-related winds and have increased our understanding of the forces driving severe winds and their spatial and temporal patterns. Data for these studies have come from airport stations maintained by the National Weather Service. Their standardization across the United States makes them ideal for research, but they are limited in their distribution. This study aims to create a similar climatology of severe surface level winds using a mesoscale network (“mesonet”). Like their ASOS (Automated Surface Observing System) and AWOS (Automated Weather Observing System) counterparts, these stations are standardized and well maintained. This …
Theoretical And Observational Analysis Of Ice Particles For Improvement Of Ice Microphysical Models, Vanessa Przybylo
Theoretical And Observational Analysis Of Ice Particles For Improvement Of Ice Microphysical Models, Vanessa Przybylo
Legacy Theses & Dissertations (2009 - 2024)
Frozen hydrometeors can grow to acquire a multitude of shapes and sizes, which influence the distribution of mass within cloud systems. Aggregates have a variety of formations based on initial ice particle size, shape, falling orientation, and the number of particles that collect. This work employs the theoretical Ice Particle and Aggregate Simulator (IPAS) as a statistical tool to repetitively collect ice crystals to derive bulk aggregate characteristics.

Plants, Soils, and Climate Faculty Publications
Taiwan's most significant natural hazards are caused by hydrological extremes resulting from excessive precipitation. The threat of extreme precipitation is posed by several different types of weather patterns that affect Taiwan. This study examined the bi‐decadal changes in rainfall by defining an extreme precipitation occurrence (EPO) for a range of event durations from 1 to 24 hr. Three major weather types affecting EPO in Taiwan were identified from 1993 to 2015: the front type consisting of either a frontal zone or convective systems developing with an apparent Meiyu cloudband, diurnal rainfall events when no apparent synoptic features are present, and …

Climatology, Variability, And Return Periods Of Tropical Cyclone Strikes In The Northeastern And Central Pacific Basins, Nicholas S. Grondin
LSU Master's Theses
Tropical cyclones (TCs) are among the most destructive meteorological phenomena and impact the lives of people who reside along the coast. The American Pacific Coastline borders the second most active TC development region in the world, the northeastern Pacific (NE Pac) basin. This region, along with the Central Pacific (C Pac)-bordering Hawaii is home to a growing population and cities engaged in a variety of economic activities, most prominently agriculture, fishing, and tourism. This study analyzes fifty-two (1966-2017) years of NE Pac and C Pac TCs through applying track data from the National Hurricane Center’s HURDAT2 and a TC size …
A Climatology Of Quasi-Linear Convective Systems In The U.S., Jacob Adam Strohm
A Climatology Of Quasi-Linear Convective Systems In The U.S., Jacob Adam Strohm
Graduate Research Theses & Dissertations
Quasi-linear convective systems, or QLCSs, are a common, organized thunderstorm mode in the U.S. Over the last fifty years, severe weather research has focused on the supercell, but, recently, QLCSs have become an increasingly important area of study. Researchers and operational meteorologists realize that this morphology is difficult to forecast and may be responsible for a large proportion of the severe weather reports in the eastern two-thirds of the U.S. This study seeks to determine the degree to which QLCSs threaten humans and their assets by, first, assessing their climatology and, second, measuring their contribution to the severe report record. …
The Influence Of Northern Hemisphere Teleconnections On The Geography Of Pacific Tropical Cyclone Genesis, Nicholas Ray Adkins
The Influence Of Northern Hemisphere Teleconnections On The Geography Of Pacific Tropical Cyclone Genesis, Nicholas Ray Adkins
Theses, Dissertations and Capstones
The research in this thesis used statistical and spatial analysis methods to test the influence of six Northern Hemisphere teleconnection patterns on the latitude and longitude components of tropical cyclogenesis occurring in the eastern and western North Pacific Ocean basins for the period 1979-2016. The Pacific-North American (PNA), West Pacific (WP), El Niño Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), Madden-Julian Oscillation (MJO), and Quasi-Biennial Oscillation (QBO) teleconnection patterns were examined independently and in combination for association with variations in cyclogenesis geography. Four of the six teleconnection patterns were found to exert an influence on cyclogenesis latitude and/or longitude in …
Analysis Of Climatological Rainfall Extremes Over The Kennedy Space Center Complex Using A High-Density Observational Network, John Lanicci, Adam Schnapp
Analysis Of Climatological Rainfall Extremes Over The Kennedy Space Center Complex Using A High-Density Observational Network, John Lanicci, Adam Schnapp
John M Lanicci
The use of observational datasets to determine the occurrence frequencies of extreme weather events has gained a lot of recent interest due to concerns about the potential regional impacts from global climate change. Extreme-value theory can quantify the return frequency of the most extreme events using climatologically short data sets and the assumption that such short climatological periods are stationary. However, the resulting analyses must be used with caution since they may not accurately reflect the potential of extreme events in the future due to climate change and variability. Accurately predicting extreme-event likelihood is important for building realistic long-range planning …

Large, Long-Lived Convective Systems Over Subtropical South America And Their Relationships With Atmospheric Teleconnections, Kyle Mattingly
Large, Long-Lived Convective Systems Over Subtropical South America And Their Relationships With Atmospheric Teleconnections, Kyle Mattingly
Mahurin Honors College Capstone Experience/Thesis Projects
This study provides a climatological assessment of persistent elongated convective systems (PECS) over subtropical South America during the austral warm seasons of 1998-2007 and a comparison of PECS frequency and physical characteristics to mesoscale convective complexes (MCCs) in the region. Relationships between the Antarctic Oscillation (AAO) and El Niño – Southern Oscillation (ENSO) teleconnections and large, long-lived convective systems (LLCSs) are explored. An average of 143 PECS and 37 MCCs occurred per warm season. PECS lasted longer on average than MCCs (17 hrs. vs. 14 hrs.) and reached a greater average maximum cloud-shield extent than MCCs (297,300 km2 vs. 256,500 …

The Weather Of 1785: An Interdisciplinary Approach To Meteorological Reconstruction Using Forensic Synoptic Analysis, Louis K. Mcnally
The Weather Of 1785: An Interdisciplinary Approach To Meteorological Reconstruction Using Forensic Synoptic Analysis, Louis K. Mcnally
Electronic Theses and Dissertations
The purpose of the work is to discern differences and similarities in synoptic-scale rneteorology by reconstructing the weather of the year 1785 on a daily basis. This is accomplished by compiling data from both homogenous and non-homogenous observational records, and from historical anecdotal evidence as recorded in diaries, archives and contemporary publications. Through this reconstruction, it is possible to infer some characteristics of the global circulation of 1785. With forensic techniques, I develop meteorological parameters from anecdotal evidence. These data are combined with meteorological observational records to produce a database from which semi-diurnal weather maps can be constructed. Sources include …
