Evaluating Drought In The United States Using The Emissivity Difference Vegetation Index, Hanisha Hirani Jan 2013

Evaluating Drought In The United States Using The Emissivity Difference Vegetation Index, Hanisha Hirani

Legacy Theses & Dissertations (2009 - 2024)

As monitoring vegetation and crops becomes increasingly important due to climate change, there arises the need for a monitoring scheme that places more weight on water availability as an indication of vegetation health and vitality. The Emissivity Difference Vegetation Index (EDVI) is the first step towards that type of monitoring scheme. With the potential for diurnal studies, there are applications towards agriculture monitoring, wildfire monitoring, and much more. EDVI is a synergetic product retrieved from microwave, visible, and infrared satellite measurements, as well as reanalysis. Since microwave measurements are more sensitive to vegetation water content, EDVI has the potential to …

An Evaluation Of Cape Tendency In Tornado Outbreaks, Timothy W. Humphrey, Lance F. Bosart May 2012

An Evaluation Of Cape Tendency In Tornado Outbreaks, Timothy W. Humphrey, Lance F. Bosart

Atmospheric & Environmental Sciences

Previous studies (e.g., Rasmussen, 2003; Thompson et al., 2003) have examined the impact that instability has on the occurrence of tornadic supercells. However, few studies (e.g., Calas et al., 2000) have examined the impact that the rate of destabilization has on the development of severe convection. Utilizing a CAPE tendency equation derived by Emanuel (1994), this study examines the impact of the rate of atmospheric destabilization on the severity of convection. Comparing six hour analyses of CAPE tendency with observed tornado tracks from the 4-6 May 2007, 5-6 February 2008, and 17 June 2010 tornado outbreaks reveals a potential correlation …

Largescale Precursors To Major Lake Effect Snowstorms Lee Of Lake Erie, Hannah E. Attard, Ross A. Lazear May 2012

Largescale Precursors To Major Lake Effect Snowstorms Lee Of Lake Erie, Hannah E. Attard, Ross A. Lazear

Atmospheric & Environmental Sciences

Lake‐effect snowstorms are primarily a mesoscale feature; however, major lakeeffect snowstorms are linked closely to their synoptic environment. Thus, a lakeeffect system which lasts for more than 24 h cannot only be explained by the boundary layer; it is also associated with the upper tropospheric flow. This research will address whether major lake‐effect snow events off of Lake Erie can also be associated with large‐scale planetary features several days prior to event onset. The goal is to aid in the forecast process by increasing the accuracy and leadtime of lake‐effect snow forecasts. This study includes 31 cases recorded from the …

The Rapid Intensification Of Hurricane Gustav (2008), Jason H. Keefer May 2012

The Rapid Intensification Of Hurricane Gustav (2008), Jason H. Keefer

Atmospheric & Environmental Sciences

Hurricane Gustav was one of two major hurricanes that occurred in the Atlantic basin during the 2008 hurricane season. The storm caused more than $6 billion U. S. dollars of damage in Haiti, Jamaica, Cuba, and along the coast of the Gulf of Mexico from 25 August 2008 to 5 September 2008. The greatest amount of damage and highest number of casualties produced by the storm can be attributed to the rapid intensification of the hurricane. Rapid intensification (RI) of a tropical cyclone is defined as an increase in maximum sustained winds by 15.4 m s⁻¹ (30 kts) in a …

A Wrf Simulation Of The Asymmetric Rapid Intensification And Trough Interaction Of Tropical Storm Gabrielle (2001), Diana Elizabeth Thomas-Abernethy Jan 2012

A Wrf Simulation Of The Asymmetric Rapid Intensification And Trough Interaction Of Tropical Storm Gabrielle (2001), Diana Elizabeth Thomas-Abernethy

Legacy Theses & Dissertations (2009 - 2024)

Despite 13 ms-1 ambient wind shear, Tropical Storm (TS) Gabrielle underwent 22 hPa pressure falls within 3 hours prior to 0900 UTC 14 September. The rapid intensification of Gabrielle was atypical due to an upper-level trough approaching from the northwest. Additionally, a convective cell developed in the downshear left quadrant of the center, moved cyclonically and inward to the 17 km radius. During this time, The Tropical Rainfall Measurement Mission (TRMM) had one of its most intense 85 GHz scattering measurements ever (Molinari and Vollaro, 2010).

Assessing Delta Oxygen-18 In The Coral Genus Isopora For Reconstructing Indo-Pacific Regional And Seasonal Climate, Gavin Lemley Jan 2012

Assessing Delta Oxygen-18 In The Coral Genus Isopora For Reconstructing Indo-Pacific Regional And Seasonal Climate, Gavin Lemley

Legacy Theses & Dissertations (2009 - 2024)

Paleoclimate reconstructions often utilize coral reefs with very long time spans such as the genus Porites and Diploastrea, because of their potential to provide centuries of continuous climate records via geochemical signatures. Smaller corals, such as the genus Isopora, have been essentially unexplored as climate archives because their small skeletons (<1 m) and short lifespans (years to decades) do not provide such continuous geochemical records. There has not been a practical application for such corals until recently. In early 2010, the Integrated Ocean Drilling Program Leg 325 (IODP-325) cored drowned fossil reefs off the Great Barrier Reef (GBR) with the objectives of reconstructing sea level and surface ocean conditions since the Last Glacial Maximum. Out of 213 massive fossil corals that were recovered, most were massive Isoporan colonies. A 30-specimen subset of these fossils range in age from ~32,000 to ~11,500 years before present with even temporal spacing, based on preliminary U/Th dating of core catcher samples. This age distribution is excellent for meeting IODP-325 objectives, but the suitability of Isopora for paleoclimate analyses remains unknown.

An Analysis Of The Formation And Evolution Of The 1989 Western North Pacific Subtropical Gyre, Brian Andrew Crandall Jan 2012

An Analysis Of The Formation And Evolution Of The 1989 Western North Pacific Subtropical Gyre, Brian Andrew Crandall

Legacy Theses & Dissertations (2009 - 2024)

This thesis conducts an observational study of a large cyclonic gyre that developed in the Western North Pacific (WNP) in late July 1989. For a period of six days, azimuthally-averaged winds at 850 hPa remained cyclonic out from the center of circulation to the 2000 km radius, with azimuthally-averaged tangential wind speeds at or greater than 10 m s-1. The gyre exhibited an asymmetric convection pattern, with the center, north and west flanks devoid of large convective areas, but the southern and eastern flanks maintained large-scale convective regions, extending as much as 4000 km in longitude.

Analysis Of Intraseasonal Convective Variability Modes Over West Africa During The Monsoon Season, Jeffrey Ceratto Jan 2012

Analysis Of Intraseasonal Convective Variability Modes Over West Africa During The Monsoon Season, Jeffrey Ceratto

Legacy Theses & Dissertations (2009 - 2024)

Intraseasonal variability of rainfall within the West African Monsoon has been shown to be an important factor in the weather of this region. Multiple factors have been found to contribute to variability at this timescale. Mounier, et al (2008) use EOF analysis to uncover and describe a quasi-stationary dipole of precipitation between the West African Monsoon system and the West Atlantic/Caribbean Sea. This mode, termed the Quasi Biweekly Zonal Dipole mode, operates on timescales of roughly 13 days. The stationary nature of this dipole is focused upon in their work, while the role of Kelvin waves in the mode are …

Remote Sensing Of Cloud Properties Using Oxygen A-Band Spectral Measurements, Siwei Li Jan 2012

Remote Sensing Of Cloud Properties Using Oxygen A-Band Spectral Measurements, Siwei Li

Legacy Theses & Dissertations (2009 - 2024)

Clouds play an important role in the climate system through their radiative effects and their vital link in the hydrological cycle. Detailed knowledge of the three dimensional (3-D) distribution of cloud macrophysical and microphysical properties is crucial to properly characterize radiative forcing by clouds and to quantify the response of the climate. In this study, a multi-layer cloud detection algorithm is developed by utilizing photon path length distributions retrieved from oxygen A-band spectral measurements. Case studies from measurements at the Atmospheric Radiation Measurement (ARM) Southern Great Plains (SGP) site demonstrate that this photon path length method can detect multi-layer clouds …

The Association Of Summer Temperatures With Hospital Admissions For Renal Diseases In New York State : A Case-Crossover Study, Barbara A. Fletcher Jan 2012

The Association Of Summer Temperatures With Hospital Admissions For Renal Diseases In New York State : A Case-Crossover Study, Barbara A. Fletcher

Legacy Theses & Dissertations (2009 - 2024)

This study assessed the association between high temperatures and increased odds of hospitalization for renal diseases which, to date, has been examined in only a small number of studies. A case-crossover design was used to study 147,885 hospital admissions with renal diagnoses during July and August, 1991-2004 in New York State. Regional temperature, humidity and barometric pressure data from automated monitors were used as exposure indicators. Using time-stratified referent selection and conditional logistic regression analysis, an overall 9% increase in odds of hospitalization for acute renal failure per 5°F (2.78°C) was found for mean temperature at a one day lag …

Convectively-Coupled Kelvin Waves Over The Tropical Atlantic And African Regions And Their Influence On Atlantic Tropical Cyclogenesis, Michael John Ventrice Jan 2012

Convectively-Coupled Kelvin Waves Over The Tropical Atlantic And African Regions And Their Influence On Atlantic Tropical Cyclogenesis, Michael John Ventrice

Legacy Theses & Dissertations (2009 - 2024)

High-amplitude convectively coupled atmospheric Kelvin waves (CCKWs) are explored over the tropical Atlantic during the boreal summer. Atlantic tropical cyclogenesis is found to be more frequent during the passage of the convectively active phase of the CCKW, and most frequent two days after its passage. CCKWs impact convection within the mean latitude of the inter-tropical convergence zone over the northern tropical Atlantic. In addition to convection, CCKWs also impact the large scale environment that favors Atlantic tropical cyclogenesis (i.e., deep vertical wind shear, moisture, and low-level relative vorticity).

Assessing The Reproducibility Of Coral Oxygen And Carbon Isotope Time Series From Fiji And Tonga And Their Application To The Reconstruction Of South Pacific Convergence Zone Movements Since The Mid-1800s, Emilie Pauline Dassie

Legacy Theses & Dissertations (2009 - 2024)

A major feature affecting the hydrology of the southern hemisphere is the South Pacific Convergence Zone (SPCZ); a band of high rainfall extending southeastward from the Western Pacific Warm Pool (WPWP). It is a key source of atmospheric water vapor and latent heating. While it is clear that the SPCZ plays a fundamental role in Earth's climate, little is known about the patterns and mechanisms responsible for interannual to century-scale changes in its position and how it may respond to global climate change.

Multiscale Analyses Of Inland Tropical Cylcone--Midlatitude Jet Interactions : Camille (1969) And Danny (1997), Matthew S. Potter

Legacy Theses & Dissertations (2009 - 2024)

TC Camille (1969) and TC Danny (1997) both interacted with the equatorward entrance region of an upper-tropospheric jet as they traversed the Appalachian Mountains; however, their societal impacts differed. During the 12-h period starting 0000 UTC 20 August 1969, 690 mm of rain fell over Massies Mill, Virginia, as TC Camille traversed the central Appalachian Mountains. On 24 July 1997, TC Danny underwent inland reintensification while moving across the Carolinas. TC Danny's minimum central mean sea level pressure decreased from 1012 hPa to 1000 hPa and its maximum sustained wind speed increased from 20 kt to 40 kt during the …

Large-Scale Influences On The Pre-Genesis Of Tropical Cyclone Karl (2010), Kyle S. Griffin Jan 2012

Large-Scale Influences On The Pre-Genesis Of Tropical Cyclone Karl (2010), Kyle S. Griffin

Legacy Theses & Dissertations (2009 - 2024)

The genesis of Tropical Cyclone (TC) Karl (2010) in September 2010 provided a unique opportunity to examine the continuing problem of understanding tropical cyclogenesis. The precursor disturbance to Karl originated from a cluster of showers east of the Windward Islands and was well sampled by ongoing field campaigns, particularly the PRE-Depression Investigation of Cloud-systems in the Tropics (PREDICT), as the targeted disturbance progressed westward. While traditional genesis theories focusing on moisture and mass fields (e.g. top-down showerhead method) can explain the initial spin-up of the disturbance several days prior to its official genesis, additional perspectives are examined in concert with …

Rainfall And Streamflow Variability In Ghana, Michael Mawutor Tanu Jan 2012

Rainfall And Streamflow Variability In Ghana, Michael Mawutor Tanu

Legacy Theses & Dissertations (2009 - 2024)

The objective of this research is to investigate the variability of rainfall and streamflow over Ghana. Analyses of rainfall shows larger daily variability and maxima amounts in the southern coastal belt than in either the middle or northern parts of the country. The high variability in rainfall at the coast is associated with sea surface temperatures (SSTs) changes over the Guinea coast. This is related to the evolution of the cold tongue over the Atlantic during the rainfall season. The results indicate that the extreme rainfall events occur as single events, but there are occasions when they occur sequentially, and …

Detailed Modeling Of Soot Size Distribution Evolution And Pollutant Formation Inside Aircraft And Diesel Engines, Chowdhury Golam Moniruzzaman

Legacy Theses & Dissertations (2009 - 2024)

Combustion emission of soot and pollutant gas species contributes to poor regional air quality near emission sources and to climate change. It is important to understand the formation mechanism and time evolution of these pollutants inside the combustion engine, through detailed modeling of combustion chemistry and microphysics as well as comparison with observation. In this thesis, two multi-zone gas parcel combustion engine models, one for aircraft engines and another for diesel engines, have been developed to study soot size distribution evolution and pollutant formation inside the engines as well as emissions. The models take into account size-resolved (sectional) soot aerosol …

Synoptic And Mesoscale Aspects Of Ice Storms In The Northeastern U.S, Christopher Castellano Jan 2012

Synoptic And Mesoscale Aspects Of Ice Storms In The Northeastern U.S, Christopher Castellano

Legacy Theses & Dissertations (2009 - 2024)

Ice storms are among the most hazardous, disruptive, and costly meteorological phenomena in the northeastern United States. The accretion of freezing rain during ice storms endangers human safety, compromises public infrastructure, and causes economic losses on local and regional scales. Furthermore, ice storms present a major operational forecast challenge due to the combined influence of synoptic, mesoscale, and microphysical processes on precipitation type. In consideration of these socioeconomic impacts and forecast issues, we have identified three primary objectives for this thesis: 1) create long-term climatologies of freezing rain and ice storms in the northeastern U.S., 2) identify antecedent environments conducive …

Appalachian Lee Troughs And Their Association With Severe Convective Storms, Daniel Thompson Jan 2012

Appalachian Lee Troughs And Their Association With Severe Convective Storms, Daniel Thompson

Legacy Theses & Dissertations (2009 - 2024)

Forecasting convective storms in the mid-Atlantic region of the U.S. (hereafter mid-Atlantic) is important because of the proximity of the convective initiation region to major East Coast cities. These forecasts can be challenging because of the weak synoptic-scale forcing for ascent and abundant convective instability typical of the mid-Atlantic warm season (May-September). As a result, mesoscale boundaries such as the Appalachian lee trough (ALT) play an important role in initiating convective storms. This thesis examines the association between ALTs and warm-season severe convective storms in the mid-Atlantic in order to understand how ALTs modulate the frequency and distribution of severe …

Evaluation Of Suny Satellite-To-Irradiance Model Performance Using Ecmwf Gems Daily Aerosol Optical Depth Reanalysis Data, Kyle Frederick Itterly

Legacy Theses & Dissertations (2009 - 2024)

The current version of the State University of New York (SUNY) radiative transfer model (RTM) uses climatological monthly averages derived from a National Renewable Energy Labs (NREL) gridded dataset to parameterize aerosol optical depth (AOD), water vapor and ozone. This is mostly due to the limited availability of high spatially and temporally resolved observations. Several global chemical transport models are analyzed and compared in depth to determine which daily AOD dataset should be implemented into the SUNY Model. After thorough comparison, the chemical transport model chosen was the Global and regional Earth-system Monitoring using satellite and in-situ data (GEMS) model …

Searching For Melting-Induced Cold-Pool Circulations In An Oklahoma Winter Storm, Gabriel Susca-Lopata May 2011

Searching For Melting-Induced Cold-Pool Circulations In An Oklahoma Winter Storm, Gabriel Susca-Lopata

Atmospheric & Environmental Sciences

This paper investigates the thermodynamic and dynamic impacts of melting precipitation through a case study of an Oklahoma winter storm. On 28 January 2005 a rain and snow event affected the state of Oklahoma. A combination of radiosonde data, wind profiler data, radar imagery and Oklahoma Mesonet surface data show that latent cooling from melting caused the surface temperatures to fall in western Oklahoma while evaporation caused surface cooling in central and eastern Oklahoma. The wind and surface pressure fields in western Oklahoma are analyzed along with radar data from Frederick Air Force Base, and some limited evidence for melting-driven …

A Preliminary Climatology Of Tropical Moisture Exports In The Southern Hemisphere, Alicia M. Bentley, Lance F. Bosart, Jason M. Cordeira May 2011

A Preliminary Climatology Of Tropical Moisture Exports In The Southern Hemisphere, Alicia M. Bentley, Lance F. Bosart, Jason M. Cordeira

Atmospheric & Environmental Sciences

Heavy precipitation events in the midlatitudes can be supported by the poleward transport of tropical air masses within the warm sector of extratropical cyclones. Previous studies have established a climatology of the four preferred pathways of tropical moisture export (TME) events into the midlatitudes over the Northern Hemisphere (NH). The present study constructs a similar climatology of TME timing and frequency over the Southern Hemisphere (SH), highlighting three preferential regions for tropicalmidlatitude interaction. These regions correspond to the locations of the: (i) South Pacific convergence zone (Pacific Ocean pathway, PO), (ii) South Atlantic convergence zone (South American pathway, SA), and …

Tropical-Extratropical Interactions And Arctic-Extratropical Interactions Conducive To Intraseasonal Variability Of The North Pacific Jet Stream, Jason Michael Cordeira Jan 2011

Tropical-Extratropical Interactions And Arctic-Extratropical Interactions Conducive To Intraseasonal Variability Of The North Pacific Jet Stream, Jason Michael Cordeira

Legacy Theses & Dissertations (2009 - 2024)

The autumnal spin up of the Northern Hemisphere (NH) general circulation is characterized by intraseasonal variability in the structure of the North Pacific jet stream (NPJ). The variability in the structure of the NPJ is often associated with large-scale flow reconfigurations over the North Pacific and North America and changes in the NH zonal available potential energy (AZ). This dissertation investigates variability in the structure of the NPJ and the NH AZ in conjunction with tropical-extratropical interactions (TEIs) and arctic-extratropical interactions (AEIs). The former are investigated in association with the El Niño-Southern Oscillation, the Madden-Julian Oscillation, and western North Pacific …

Review Of The Simulation Of The Precis Regional Climate Model Over Tropical South America Using Gcm And Reanalysis Lateral Boundary Conditions, Dana Mcglone

Legacy Theses & Dissertations (2009 - 2024)

High-resolution regional climate models (RCM) run over a limited domain are increasingly used to simulate seasonal to interannual climate variability over South America and to assess the spatiotemporal impact of future climate change under a variety of emission scenarios. Global climate models (GCM) are often too coarse to resolve local circulations and the topography of the Andes, leading to problems with simulation of temperature and precipitation patterns throughout the domain. A RCM model can also better represent the climate at a regional scale; however, they are subject to errors introduced by the driving global models. For this study, the Hadley …

Significance Of Hno3 Acid Photolysis On Surfaces In Tropospheric Chemistry, Honglian Gao Jan 2011

Significance Of Hno3 Acid Photolysis On Surfaces In Tropospheric Chemistry, Honglian Gao

Legacy Theses & Dissertations (2009 - 2024)

The reactive nitrogen trace gases (NOy) including nitrogen oxides (NOx) and their secondary products are known to cause ground-level ozone pollution, photochemical smog, acid deposition, and overall air quality degradation. NOx was believed to be permanently removed from the atmospheric by HNO3 formation and deposition. However, our laboratory experimental results show that HNO3 can be remobilized back to photochemically labile HONO and NOx (re-NOx-ification). We have verified and quantified HONO and NOx production from the photolysis of HNO3 on various surfaces, including Pyrex, leaves of plants, and other environmentally relevant …

Easterly Waves And Tropical Cyclogenesis In The Caribbean, Kay Louise Shelton Jan 2011

Easterly Waves And Tropical Cyclogenesis In The Caribbean, Kay Louise Shelton

Legacy Theses & Dissertations (2009 - 2024)

This thesis is concerned with the evolution of easterly waves in the Atlantic and Caribbean and their relationship to tropical cyclogenesis. Motivation for this study is the apparent "genesis hole" in the eastern Caribbean and the lack of knowledge regarding the evolution of the transient disturbances passing through this region. The environment of the Caribbean is reviewed revealing large vertical wind shear and dry mid-levels as the key factors determining the presence of the genesis hole.

The Influence Of The Great Lakes On Mcs Formation And Development In The Warm Season, Alan Frederick Srock Jan 2011

The Influence Of The Great Lakes On Mcs Formation And Development In The Warm Season, Alan Frederick Srock

Legacy Theses & Dissertations (2009 - 2024)

This study focuses on how near-surface thermal boundaries that form near the Great Lakes during the warm season can contribute to the formation of mesoscale convective systems (MCSs). Differential heating across land-water interfaces can create a cold dome of air over the lake; convection may develop when the relatively-cold dome of air becomes deep enough to enable air parcels that intersect these boundaries to reach their level of free convection. A radar-based climatology of MCS events surrounding the Great Lakes for 2002-2005 showed that MCSs frequently form in the vicinity of the Great Lakes. Composites of MCS events over the …
