Hernandez, Celina Anne (2009-05-15)Variations in characteristics of tropical deep convection are examined for an association with the stratospheric quasi-biennial oscillation (QBO). Eight years (1998-2005) of Tropical Rainfall Measuring Mission (TRMM) ...
-
Fliegel, Jonathan 1988- (2012-09-24)The Shared Mobile Atmospheric Research and Teaching Radar (SMART-R) is a truck-mounted C-band, Doppler radar that was deployed during the Dynamics of the Madden-Julian Oscillation (DYNAMO) / Cooperative Indian Ocean ...
-
Keene, Kelly M. (2012-10-19)The accurate prediction of warm-season convective systems, and the heavy rainfall and severe weather associated with them, remains a challenge for numerical weather prediction models. This study looks at one such circumstance ...
-
Seroka, Gregory Nicholas (2011-08-08)The NASA Kennedy Space Center (KSC) is situated along the east coast of central Florida, where a high frequency of lightning occurs annually. Although cloud-to-ground (CG) lightning forecasting using radar echoes has been ...
-
DePasquale, Amanda Michele (2013-07-05)The Madden-Julian Oscillation (MJO), a tropical phenomenon that exists on the time scale of 30-90 days, commonly initiates over the Indian Ocean and slowly propagates into the western Pacific as a series of convective ...
-
Mosier, Richard Matthew (2011-02-22)Ten years (1997 - 2006) of summer (June, July, August) daytime (14 - 00 Z) Weather Surveillance Radar - 1988 Doppler data for Houston, TX were examined to determine the best radar-derived lightning forecasting predictors. ...
-
Lin, Yun (2018-05-05)In this study, the regional-scale aerosol effects are quantitatively assessed under various weather conditions by conducting numerical modeling studies to improve the understanding of physical processes involved in ...
-
Zarate Jimenez, Luz Areli (2018-08-04)Understanding the circulation of the oceanic currents provides information to mitigate the impact of hazards and to respond timely in the case of an emergency by making critical decisions promptly. In early 2016, the ...
-
The Sensitivity of Rainfall Distributions to Time, Space, and the Environment over Kwajalein Atoll Campbell, Lily JoyNorth of the equator, winds converge causing bands of heavy rain in a region called the Intertropical Convergence Zone (ITCZ). Due to the small-scale processes that are not fully represented by weather models, modeled ...
-
Vogel, Jonathan 1988- (2012-08-21)The aerosol direct and indirect effects were investigated for three specific cases during the March 2000 Cloud IOP at the SGP site by using a modified WRF model. The WRF model was previously altered to include a two-moment ...
-
Spatiotemporal Dynamics of Solar Radiation in the Himalaya: Topographic Forcing and Glacier Dynamics Dobreva, Iliyana Dancheva (2019-10-30)Glaciers across the Himalaya exhibit significant spatial variations in morphology and dynamics. Climate, topography and debris cover variations are thought to significantly affect glacier fluctuations and glacier sensitivity ...
-
Choi, Janghwoan (Texas A&M University, 2007-04-25)This dissertation describes spatio-temporal properties of rainfall. Rainfall in space was modeled by a precipitation areal reduction factor (ARF) using a NEXRAD image. The storms are represented as ellipses, which are ...
-
Sullivan, Richard Marshall (2022-07-28)The North Atlantic Subtropical High (NASH) is a dominant driver of regional hydroclimate in the Intra-American Seas (IAS). During the boreal summer, the NASH expands westward along steep land-sea temperature gradients. ...
-
Leathe, Dylan Alexander (2023-04-17)In the years following large scale volcanic eruptions, the global energy budget is modulated by sulfate aerosols, which have direct and indirect effects on radiation. Large eruptions alter the vertical temperature structure ...
-
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 ...
-
Dupuis, Christopher M (2016-04-04)The Lomb-Scargle discrete Fourier transform (LSDFT) is a fairly popular technique for analyzing time series within the astronomy community. However, this algorithm is largely unknown in many other disciplines, despite many ...
-
McKinney, Christopher Michael (2009-05-15)Five severe convective cells over North Texas from three separate dates were examined to determine what three dimensional, or “total” lightning data can add to the understanding of a convective cell’s intensity, propagation, ...
-
Cathey, Stephen Christopher (2012-02-14)Understanding the underlying causes of tropical cyclone formation is crucial to predicting tropical cyclone behavior in a warming environment, given the Earth's current warming trend. This study examines two sets of ...
-
Zamora, Ryan Alexander (2016-10-20)This research examines tropical cyclones in simulations of climates very different from modern. The tropical cyclones are simulated via two techniques: explicitly tracking TC-like structures in global climate model output, ...
-
Hale, Jacob Martin (2023-04-04)Lightning behavior within Tropical Cyclones (TCs) has been studied previously; however, there are notable gaps and contradictions in how changes in lightning activity specifically relates to intensification, weakening, and ...
