The following study examines the spatiotemporal response of the local scale and large scale environment to tropical cyclone (TC) passage. The research presented here is broken up into three chapters that can be separated into two parts....
The European Centre for Medium-Range Forecasts Reanalysis-40 and National Centers for Environmental Prediction (NCEP)/Department of Energy reanalyses are downscaled over the eastern Caribbean and Lesser Antilles using the NCEP-Scripps...
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...
Nitrogen oxides (NOx) produced by lightning (LNOx) play an important role in atmospheric chemistry, including the formation of tropospheric ozone (O3). Chemical transport models such as the Weather Research and Forecasting (WRF-Chem)...
The June-September (JJAS) 2000-2007 NCEP coupled Climate Forecasting System (CFS) global hindcasts are downscaled over the North and South American continents with the NCEP-Scripps Regional Spectral Model (RSM) with anomaly nesting (AN)...
Mid-ocean ridge interactions with hotspots strongly affect mantle flow processes. This study analyses the anomalies produced as a result of the interaction between a hotspot and an oceanic ridge-ridge-ridge triple junction, in close...
While natural disasters can often be catalysts for change, understanding where to begin changing can be discovered by looking at the science and history of the affected area. Hurricane Sandy's unprecedented landfall in October 2012 began...
Accurate and Precise Determination of Low Concentration Iron, Arsenic, Selenium, Cadmium, and Other Trace Elements in Natural Samples by Octopole Collision/Reaction Cell (CRC) Equipped Quadrupole-ICP-Ms
An improved method for accurate and precise determination of trace quantity dissolved metals and metalloids in natural samples by Octopole Collision/Reaction Cell (CRC) equipped Quadrupole-Inductively Coupled Plasma-Mass Spectrometry ...
This study examines the degree of uncertainty that occurs in atmospheric transport and dispersion (ATD) modeling due to using different parameterizations of physical processes such as shortwave and longwave radiative processes, ...
Microwave satellite observations provide useful information about atmospheric temperature and water vapor. This insight could be used to improve hurricane forecasting through the assimilation of this data into Numerical Weather...
Apalachicola Bay is a productive estuary located in the northern Gulf of Mexico. The high productivity is, in part, the result of the Apalachicola River delivering freshwater and nutrients to the Bay. Nutrient input supports high levels...
Mode water formation has long been treated as a buoyancy flux problem; however this approach fails to explain all of the variability of mode water. A number of different approaches have been demonstrated to explain more of this...
Gridded QuikSCAT data has been used to show that a strong confluence zone of the Southeast Pacific Intertropical Convergence Zone (SITCZ) existed in 2000 – 2002 during boreal spring, and the Panama wind jet contributes to its variability...
Changes in the amount of dissolved oxygen concentration in the Sea of Japan (SOJ) over a number of years have been hypothesized to be due to the amount and depth of deep convection in this region. The first observations of the changes in...
The Bering Strait's Grip On The World Climate: The Holocene interglacial period of the last 10, 000 years and the penultimate interglacial ~125, 000 years ago have been characterized by distinctly stable climates. During the intervening...
Seamounts are largely unexplored undersea mountains rising abruptly from the ocean floor. These unique habitats can support an increased abundance and diversity of organisms, due to increased flow rates, the presence of hard substrates, ...
The advent of ensembles permits forecasters to have an implied level of confidence based upon the level of (dis)agreement among those ensembles. However, there are occasionally situations where the ensemble members may agree but be in...
Metallic nodules are common in metamorphosed ordinary chondrites. The origin of metal nodules has been debated because the mechanism of the formation of metal nodules is not known. Several proposed scenarios, e.g., the metal nodules and...
The low-frequency signals (LFS) of climate variables such as temperature and pressure often contain variability as a result of the nonlinear and non-stationary nature of Earth's climate system. Occasionally, as in the case of the North...
Stable isotopes of oxygen, carbon and nitrogen were used to understand the ecological changes induced by human activities. The existing method developed by McLaughlin et al. (2004) for determination of the oxygen isotopic composition of...
Tropical cyclone accumulated cyclone energy (ACE) has exhibited strikingly large global interannual variability during the past 40-years. In the pentad since 2006, Northern Hemisphere and global tropical cyclone ACE has decreased...
In this paper we examine the variations of the boreal summer season sea breeze circulation along the Florida panhandle coast from relatively high resolution (10 km) regional climate model integrations. The 23 year climatology (1979-2001)...
Sea Surface Temperatures (SSTs) are an important measure of our current weather and climate, as well as an essential variable in both short and long term weather forecasting. Infrared SST retrievals are reliant on passive sensors, and...
A new metric for identifying severe tornado (F3+) alleys is presented. Regions are distinguished by average F-scale values with a minimum of 15 severe tornado events within 200km. Five distinct "severe tornado alleys" are described...
This dissertation research has used stable and radioactive isotope techniques to address several important issues in paleoclimate and paleoecoloical research which includes the reliability of using stable carbon isotope composition of...
During IODP Leg 317 off the east coast of New Zealand, three continental shelf sites (U1351, U1353 and U1354) and one continental slope site were cored. Sedimentary sequences representing shallow water depositional cycles were recovered...
Satellite observations have revealed a small-scale (< 1000 km) air-sea coupling in regions of strong sea surface temperature (SST) gradients (e.g., fronts, currents, eddies, and tropical instability waves), where the surface wind and...
The recent reports of methane in the atmosphere of Mars, as well as the findings of hypersaline paleoenvironments on that planet, have underscored the need to evaluate the importance of biological (as opposed to geological) trace gas...
Ocean turbulence is responsible for stirring and spreading ocean tracers, and contributes to the mean circulation as eddy bolus fluxes. The influence of the eddies on the mean circulation becomes particularly important in regions where...
Ice and snow particles have a great, yet poorly understood impact on the Earth's climate system. One of the difficulties of studying snow particles is their irregular shape. While spheres and even oblate spheroids backscatter radiation...
This research project seeks to evaluate the rainfall forecast accuracy of the GEFS (Global Ensemble Forecast System) following the 2010 model update, analyzing the Atlantic September 2010 Hurricane Karl as a case study. Archived...
