Hodapp, Charles Lee (2009-05-15)Two mesoscale convective systems (MCSs) passed over the Houston Lightning Detection and Ranging (LDAR) network on 31 October 2005 and 21 April 2006. As the MCSs traverse the LDAR network, the systems slowly mature with a ...
-
Zamora, Ryan Alexander (2013-07-02)The interplay between convective processes and the stabilizing effects of largescale systems remains debated, especially for warmer climates. We study sets of simulations of past and present climates in which carbon dioxide ...

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 ...
-
Casey, Sean Patrick (2009-06-02)Convective clouds in the tropics can be grouped into three categories: shallow clouds with cloud-top heights near 2 km above the surface, mid-level congestus clouds with tops near the 0°C level, and deep convective clouds ...

Ely, Brandon Lee (Texas A&M University, 2008-10-10)The Houston LDAR II network is an array of twelve VHF time-of-arrival (TOA) sensors operated by Texas A&M University. The goals of the network are to conduct indepth studies of thunderstorm electrification and provide ...
-
Zhu, Xiaojie (2013-05-17)This dissertation reports on studies on the role of the mean state in modulating climate variability at interannual and decadal time scales. In the atmosphere, the nonlinear superposition of mean flow and anomalous flow ...
-
Fiaz Ahmed Rafi Ahmed, . (2016-11-29)The interaction between moist convection and the environment that engenders it is a problem that spans multiple scales. In this study, the problem is approached using a suite of observational and modeling tools. The first ...
-
Myoung, Boksoon (2009-05-15)Since Texas normally receives most of its precipitation in the warm season, precipitation deficits in summertime may bring serious agricultural and hydrological disasters. While the underlying physical processes of summer ...
-
Ge, Xiao (2022-12-08)A 9-year nature run (free run) and two assimilative runs of R-CESM are used to reveal the mechanisms of Loop Current (LC) deep dynamics. The numerical outputs are compared to the in-situ observations. Our results indicate ...
-
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 ...
-
Huaman Chuquihuaccha, Lidia (2021-11-17)The interaction of large-scale atmospheric circulations with convective systems in two tropical regions (i.e., the East Pacific and West Africa) is studied using field campaign, reanalysis, and satellite datasets. In the ...

Monroe, Emily Elizabeth (2016-12-06)The western rising branch of the local Walker circulation over the Atlantic intensifies as a result of enhanced convection and the associated latent heat release over the greater Amazon region. Monthly measurements gathered ...
-
Etten-Bohm, Montana (2022-03-28)Lightning can have many societal and environmental impacts, and the ability of a global climate model (GCM) to correctly parameterize lightning has become of utmost importance as lightning has recently been named an essential ...
-
Yang, Chunxue 1984- (2012-12-06)Long-term changes of El Niño/Southern Oscillation (ENSO) are studied with the ensemble run of Simple Ocean Data Assimilation (SODA 2.2.6) and the Coupled Model Intercomparison Project Phase 5 (CMIP5). An eight member ocean ...
-
McRoberts, Douglas B (2014-12-08)The demand for real-time drought information in recent years led to the development of a suite of objective drought indicators that relies on the high-resolution Stage IV precipitation estimates that are produced each day ...
-
Lee, Keun-Hee (2012-02-14)The direct and indirect effects of aerosols on the hurricane ‘Katrina’ have been investigated using the WRF model with a two-moment bulk microphysical scheme and modified Goddard shortwave radiation scheme. Simulations of ...
-
Wu, Qiaoyan (2009-06-02)This study uses high resolution satellite measurements from the Tropical Rainfall Measuring Mission (TRMM), Quick Scatterometer (QuikSCAT) and Special Sensor Mi¬crowave Imager (SSM/I) to investigate the variability of sea ...
-
Stachnik, Justin Paul (2013-03-25)This dissertation presents a series of work related to the representation of the Hadley circulation (HC) in atmospheric reanalyses and general circulation models (GCMs), with connections to the underlying tropical and ...

Ogle, Marcus 1982- (2012-12-12)Commonly referred to as “red tide”, harmful algal blooms (HABs) formed by Karenia brevis occur frequently in the Gulf of Mexico (GOM). A bloom is defined as cell abundances >105 cells L-1. This thesis will focus primarily ...
