Modeling sea surface height in the Gulf of Mexico
… mixed layer heat content and is an input for hurricane intensity models. A significant ocean feature in the Gulf of Mexico is the Loop Current (LC) which sheds warm eddies into the Gulf of Mexico at irregular intervals, which adds to the variability in monthly SSH readings beyond seasonal …

Secondary Eyewall Formation as a Response to Evolving Tropical Cyclone Wind Structure
… as well as fluctuations in tropical cyclone intensity, making secondary eyewall formation an important problem for forecasters aiming to refine predictions of both tropical cyclone intensity and damage. In this thesis, we first provide an overview of current work on secondary eyewall …

Wind wave tank for experimental investigation of momentum and enthalpy transfer from the ocean surface at high wind speed
Thermodynamic analysis and numerical modeling of hurricane intensity has shown that its is controlled by the enthalpy transfer from the ocean surface and by drag. Direct measurements of drag, evaporation, and sensible heat transfer are not easily performed on the high seas. Therefore, a wind wave …

Investigation of climate change impact on hurricane wind and freshwater flood risks using machine learning techniques
Hurricane causes severe damage along with the U.S. coastal states. With the potential increase in hurricane intensity in changing climate conditions, the impacts of hurricanes are expected to be severer. Current hurricane risk management practices are based on the hurricane risk assessment without …

Tropical cyclone precipitation risk in the Southern United States
… data from 1980 to 2010 and the Coupled Hurricane Intensity Prediction System (CHIPS) model. The climatology is compared to hourly rainfall estimates from the WSR-88D Next Generation Weather Radar (NEXRAD-II) system. In general the synthetic TCP estimates show good agreement with …

Strong wind events across Greenland’s coast and their influence on the ice sheet, sea ice and ocean
… of Ammassalik at the coast, where it can reach hurricane intensity. In this region, the cold air, which formed over the northern ice sheet, is suddenly released during intense downslope wind events and spills over the Irminger Sea where the cold and strong winds can drive heat fluxes of up to …

An Ensemble Numerical Modeling Study of Alantic Basin Hurricane Intensification
… due to the difficulty of forecasting cyclone intensity and the unclear mechanism by which a hurricane my undergo explosive deepening. Ensemble numerical modeling studies of six tropical cyclones from 2009, 2010 and 2011 which underwent periods of strong intensification are conducted here. The …

Assessing impact of the sulfate aerosol first indirect effect on tropical cyclone activity
… geophysical hazards. Studies suggest that the intensity of TCs will increase due to the thermodynamic effects of anthropogenic greenhouse gas input. In contrast, while aerosols are shown to have an overall cooling effect on global climate, their impact on TCs is not yet well-understood. This …

The use of gamma distributions to quantify the dependence of cloud particle size distributions in hurricanes on cloud and environmental conditions
Mesoscale models that predict the temporal evolution of tropical cyclones (TCs) are sensitive to the representation of cloud microphysical processes through their effect on modeled latent heat release. The cloud parameterizations used in such models make assumptions about the size distributions …
