With current computational limitations, the accuracy of high resolution precipitation forecasts has limited temporal and spatial resolutions. Forecast accuracy drops dramatically after a 24 hour forecast. Current operational mesoscale...
This work attempts to express the change, induced by the introduction of stratification, of the Rossby eigen-modes of a closed basin with bottom topography, filled with a uniform fluid in the unperturbed configuration. Such a...
The Tongue of the Ocean (TOTO) region located within the Bahamas archipelago is a relatively under-studied region in terms of both its biological and physical oceanographic characteristics. This region is comprised of a deep trough along...
In this study, a scale interactions and energetics formulation is utilized to examine the kinetic (KE) and available potential energy (APE) maintenance of the Madden Julian Oscillation (MJO). An analysis that computes the energy exchange...
The influence of a geostrophically balanced or potential vorticity (PV) background flow on gravity wave propagation is examined using a rotating shallow water model. The system is analyzed in the context of a perturbative expansion that...
Recent proxies analysis suggest that, at the end of the last glacial, there was a significant increase in the injection of Agulhas rings into the South Atlantic (SA). This brought about a dramatic increase in the salt-influx (from the...
The need for a surface based, dense meteorological observation network in Florida has long been recognized. In 2002, scientists across the state of Florida joined together with the National Science Foundation, the REALM Project, the...
In order to understand the physical mechanisms of the Australian summer monsoon, cyclostationary EOF analysis was conducted on the 23-year (1979-2002) Xie- Arkin pentad summer precipitation data and other key physical variables over the...
This dissertation explores wildfire dynamics. Chapters 2 and 3 are peer reviewed journal articles that present an understanding of three-dimensionality in grass fires and how it affects forward rate of spread (ROS) of the fire. In...
The hurricane boundary layer thickness as determined through the uniform constant BL depth model and varying prescribed BL depth model presented by Smith and Vogl (2008) is compared to the Troen and Mahrt (1986) method. Smith and Vogl...
This study uses the high-resolution infrared radiation AVHRR (Advanced Very High Resolution Radiometer)-only and microwave radiation AMSR (Advanced Microwave Scanning Radiometer)+AVHRR sea surface temperature (SST) datasets to analyze...
The goal of this study is to further investigate the relationship between the microphysical processes of a tropical cyclone and its intensification. Hydrometeors such as rainwater, cloud ice, cloud water, snow, and graupel play a...
Rainfall patterns over the Southeast U.S. have been found to be connected to the El Niño-Southern Oscillation (ENSO). Warm ENSO events cause positive precipitation anomalies and cold ENSO events cause negative precipitation anomalies....
Changes in wind direction in association with the phases of the El Niño-Southern Oscillation (ENSO) are identified over the Southeast region of the United States during the winter season (December-February). Wind roses, which depict the...
Climate feedbacks represent mechanisms that alter the sensitivity of the earth climate system. It has been suggested that the current spread in climate model sensitivity to a CO2 forcing is a result of different treatments of climate...
Tropical cyclone track forecasts have improved greatly in recent years. However, intensity forecasts still pose a large problem in tropical meteorology. Several theories have been developed over the past fifty years which attempt to...
The wind speed and wind stress over the Southern Ocean (SO) is compared from the QSCAT, COAPS, ERA-Int, JRA25 and NCEP2. From the results of comparison, NCEP2 seems to poorly represent wind speed in the SO. In the summer months, the...
For many years tropical cyclone superensemble has shown remarkable skill in forecasting Atlantic tropical cyclone track and intensity. In this project tropical cyclone superensemble is applied to Eastern Pacific tropical cyclone...
While tropical cyclone (TC) track forecasting has improved noticeably over the last twenty years, intensity forecasting has remained somewhat of an enigma to forecasters. Despite increased computing capabilities and more sophisticated...
Twenty turbulent flux parameterizations are compared globally and regionally with a focus on the differences associated with episodic events. The regional focus is primarily upon the Gulf Stream and Drake Passage, as these two regions...
Scatterometer observations of vector winds are used to examine the amplitudes of synoptic and diurnal cycles. Scatterometers have the advantage of providing global coverage over water; however, irregular temporal sampling complicates the...
Particle-laden buoyant jets (PBJ) are free-convective flows that contain particles. Many studies have examined pure thermal plumes, discussing a symmetric self-similar structure that is common in the plume literature. Other studies have...
There has been great energy focused on tropical cyclone intensity forecasting over the past thirty years. Toward the goal of providing more accurate intensity forecasts, the role of the environment of a tropical storm has been studied at...
The lack of satellite imagery prior to 1966 and limited aircraft reconnaissance has led to an indefinite number of tropical cyclones (TCs) in the Atlantic Basin remaining undetected by traditional surface observational networks. As a...
