Homeyer, Cameron Ross (2012-10-19)Stratosphere-troposphere exchange processes are responsible for controlling the distribution of chemically and radiatively important trace gases in the upper troposphere and lower stratosphere. Extensive characterization ...
-
Kinney, Nichole 1987- (2012-08-21)With increasing computational power, simulations of regional climate are now becoming possible on convective-resolving grids, thus eliminating the need for a convective parameterization. In the present study, a series of ...
-
Guarriello, Felicia Rose (2016-08-05)Supercell thunderstorms simulated using the numerical model CM1 are used to analyze the effects of low-level vertical wind shear on near-ground rotation in the storm. In particular, the parameters being assessed are the ...

Bai, Hedanqiu; Deranadyan, Gumilang; Schumacher, Courtney; Funk, Aaron; Epifanio, Craig; Ali, Abdullah; Endarwin, FNU; Radjab, Fachri; Adriyanto, Riris; Nurhayati, Noer; Nugraha, Yudha; Fauziah, Annisa (American Meteorological Society, 2021-03)Afternoon deep convection over the Maritime Continent islands propagates offshore in the evening to early morning hours, leading to a nocturnal rainfall maximum over the nearby ocean. This work investigates the formation ...
-
Wang, Shuguang (2009-05-15)The dissertation first investigates gravity wave generation and propagation from jets within idealized vortex dipoles using a nonhydrostatic mesoscale model. Several initially balanced and localized jets induced by vortex ...
-
Brown, Matthew (2018-08-03)Supercell thunderstorms are simulated using a numerical model in order to probe the effects of changing low-level moisture, and thus lifting condensation level (LCL), on outflow characteristics and the evolution of ...
-
Hopper, Larry (2012-02-14)This dissertation establishes a precipitation climatology for common storm types and structures in southeast Texas, investigating diurnal, seasonal, and interannual rainfall variations in addition to climatological differences ...
-
Arcomano, Troy J (2022-12-08)This study investigates the applications of machine learning (ML) to weather and climate modeling. We first show the potential for data-driven weather prediction by creating a low resolution, ML-based global atmospheric ...
-
Hawblitzel, Daniel Patrick (Texas A&M University, 2006-08-16)This study examines the dynamics and predictability of the mesoscale convective vortex (MCV) event of 10-13 June 2003 which occurred during the Bow Echo and Mesoscale Convective Vortex Experiment (BAMEX). The MCV formed ...
-
Serino, Michelle Marie (2018-01-10)While supercell thunderstorms are the storms with the greatest potential of producing tornadoes, the majority of supercells do not produce tornadoes. Recent work has demonstrated that low-level (LL) vertical wind shear and ...
-
Zhang, Meng (Texas A&M University, 2008-10-10)In this study, a month-long simulation of gravity waves over North America and North Atlantic Ocean is performed using the mesoscale model MM5 for January 2003, verified with Advanced Microwave Sounding Unit-A (AMSU-A) ...
-
Li, Yi (2022-12-07)The behavior and dynamics of the surface stress boundary condition are explored, both in terms of the basic physics of the condition and the associated implementation in finite-difference models. Numerical experiments are ...
-
Bremenkamp, Marc (2021-07-15)The evolution of supercell thunderstorm environments during the evening transition provides mechanisms that would seemingly offer competing contributions to updraft accelerations: low-level cooling and associated stabilization ...
-
Bai, Hedanqiu (2021-12-09)The diurnal cycle is a fundamental temporal scale in the tropics. Using a combination of observations and numerical models, this dissertation aims to advance the understanding of the diurnal cycle of winds and convection ...
