The effects of ocean eddies on tropical cyclones
… this study is to understand the interactions of tropical cyclones with ocean eddies. In particular we examine the influence of a cold-core eddy on the cold wake formed during the passage of Typhoon Fanapi (2010). The three-dimensional version of the numerical Price–Weller–Pinkel (PWP) vertical …

The tropopause region thermal structure and tropical cyclones
… Second, what sets the thermodynamic limits of tropical cyclone intensity across the seasonal cycle? The link between these subjects is tropical cyclone outflow, which often reaches into the tropopause region, allowing the thermal structure there to impact tropical cyclone potential intensity. A …

Recovery from Minor Tropical Cyclones: the Response of Faith-based Organizations and Government Agencies to Minor Tropical Cyclones in Biloxi, Mississippi
… Geography; in contrast, the aftermath of minor tropical cyclones is understudied. Along the Gulf Coast in 2020 and 2021, more minor tropical cyclones made landfall then major hurricanes (NOAA, 2021). Despite the frequency of minor tropical cyclones, few studies have considered the resources and …

Teleconnective Influences on the Strength of Post-tropical Cyclones
<p>Over the 1951-2009 time period, 47% of all tropical systems in the Atlantic Basin transitioned to post-tropical storms. These storms are capable of producing hurricaneforce winds, torrential, flooding rains and storm surge that floods coastal areas. This study adds to previous climatological …

Diurnal analysis of intensity trends in Atlantic tropical cyclones
… may exist in observational variables related to tropical cyclone (TC) intensity. Prior studies document a significant diurnal signal in moist convection across tropical regions. Since convection becomes more pronounced in intense TCs, daily solar insolation possibly affects observed TC …

Observation and Tracking of Tropical Cyclones Using Resolution Enhanced Scatterometry
… L2B data product winds, to observe and track tropical cyclones. Resolution enhanced winds are found to provide additional storm structure such as inner core size and structure and the presence of multiple eyewalls compared with standard resolution winds. The 2.5~km winds are also able to …

African Easterly Waves: Evolution and Relationship to Atlantic Tropical Cyclones
… less than 20% of all African waves originate tropical cyclones (including hurricanes). It is of interest to investigate if African waves involved in cyclogenesis possess special characteristics, or if the environment in which they are embedded is the sole factor that determines if cyclogenesis …

Composite structure of tropical cyclones in the SW Indian Ocean
This work examines SW Indian Ocean tropical cyclone (TC) structure as a function of movement using ECMWF gridded data. Analyses of the mean summer climate for the period 1987 1992 shown that conditions conducive to the development ofTCs are present between the latitudes 5° and 15°S. Six westward …

Characteristics of tornadoes associated with land-falling Gulf Coast tropical cyclones
Tropical cyclone tornadoes are brief and often unpredictable events that can produce fatalities and create considerable economic loss. Given these uncertainties, it is important to understand the characteristics and factors that contribute to tornado formation within tropical cyclones. This thesis …

Monsoon surges, tropical cyclones and extreme rainfall events in NW Madagascar
… in 24 hours at Maintirano during the passage of tropical cyclone (TC) Cynthia, an eastward moving TC from the Mozambique Channel. The second flood event occurred in 1992and brought 347 mm of rainfall in 24 hours at Mahajanga due to the passage of TC Bryna, a westward moving TC from the Indian …

Extreme rainfall intensities and long-term rainfall risk from tropical cyclones
… of extreme rainfall intensities caused by tropical cyclones (TCs) in coastal areas. The mean rainfall field associated with a TC with maximum tangential wind speed Vmax, radius of maximum winds Rmax, and translation speed Vmax, is obtained using a physically-based model, whereas rainfall …

Horizontal vorticity redistribution and vortex alignment in developing and mature tropical cyclones
… a vortex is examined here in the context of tropical cyclone (TC) structure and intensity change. Aspects of the horizontal vorticity mixing dynamics are first presented in a novel analysis of high temporal resolution wind fields derived from airborne dual-Doppler observations of Hurricane …

The impact of upper tropospheric temperatures and radiation on idealized tropical cyclones
… temperature acts as a powerful constraint on tropical cyclone (TC) intensity and structure. The physical mechanisms by which the upper tropospheric thermal structure and radiative forcing impact TC intensity and structure have not been fully explored however, due in part to limited …

Modeling the impact of land surface feedbacks on post landfall tropical cyclones
… systems. Land surface can affect landfalling tropical cyclones in two ways: (i) when the cyclone is offshore and land can influence cyclones by introducing dry (or moist) air that can weaken (or strengthen) the organized convective structure of cyclones, and (ii) land can affect the evolution …

Upper ocean variability and tropical cyclones in the South West Indian Ocean
Tropical cyclones (TCs) are the most devastating weather phenomenon in nature with the powerful storm surge events occurring when severe and large TCs make landfall along coastlines. Although there have been significant strides in the TC track forecasts over the last 30 years, skills in TC …

An Overview and Evaluation of SynthETC: A Statistical Model for Extra-Tropical Cyclones
<p>Extratropical cyclones (ETCs) are the most common weather phenomena affecting the United States, Canada, and Europe. They can pose serious hazards over large swaths of area. In this thesis, a statistical model of ETCs, called SynthETC, is discussed. The model accounts for the for genesis, track …
