Smith, Christina Lynn (Texas A&M University, 2005-08-29)The mixing layer (ML) heights inferred from radiosondes, wind profilers, airborne lidar, airborne microwave temperature profiler (MTP), and in-situ aircraft data were compared during the Texas 2000 Air Quality Study in the ...
-
Mutlu, Atilla (2009-05-15)There is a need for a robust and accurate technique to measure ammonia (NH3) emissions from animal feeding operations (AFOs) to obtain emission inventories and to develop abatement strategies. Seasonal studies were conducted ...
-
Qian, Tingting (2010-07-14)Two problems in mesoscale wave dynamics are addressed: (i) wave-turbulence interaction in a breaking mountain wave and (ii) gravity wave generation associated with coastal heating gradients. The mean and turbulent structures ...
-
McRoberts, Douglas Brent (Texas A&M University, 2008-10-10)This research looks at the past century of Texas and New Mexico climate in order to create datasets sufficient for documenting climatic variations. Inhomogeneities in climate records are defined as variations in climatic ...
-
Sippel, Jason A. (2010-01-15)Through methodology unique for tropical cyclones in peer-reviewed literature, this study explores how the dynamics of moist convection affects the predictability of tropical cyclogenesis. Mesoscale models are used to perform ...

Nielsen-Gammon, John W.; Fipps, Guy; Caldwell, Todd; McRoberts, D. Brent; Conlee, Don (Texas Water Development Board, 2017-12-21)Information was collected on existing mesonets, potential evapotranspiration networks, and stakeholder needs, in support of a comprehensive feasibility study for a Texas statewide evapotranspiration network. This report ...
-
Frey, Ashley E. (2010-07-14)Flooding inundation during hurricanes has been very costly and dangerous. However, the impact of climate change on hurricane flooding is not well understood at present. As sea surface temperatures increase, it is expected ...
-
Schulze, Karl Werner (Texas A&M University, 2004-09-30)The VAD Wind Profile (VWP), a time-height display of winds computed by the National Weather Service's WSR-88D radar, is known on occasion to have errors at night during the fall and spring seasons. Several studies, such ...
-
Han, Sang-Ok (Texas A&M University, 2005-11-01)This study developed a parameterization method to investigate the impacts of inhomogeneous land surfaces on mesoscale model simulations using a high-resolution 1-d PBL model. Then, the 1-d PBL model was used to investigate ...
-
McNear, Veronica Ann (Texas A&M University, 2007-09-17)An increase in the amount of lightning and rainfall over the Houston area, compared to the surrounding rural areas, has been well documented in previous studies. The placement of a Shared Mobile Atmospheric Research and ...
-
Aksoy, Altug (Texas A&M University, 2005-11-01)The performance of the ensemble Kalman filter (EnKF) in forced, dissipative flow under imperfect model conditions is investigated through simultaneous state and parameter estimation where the source of model error is the ...
-
Coburn, Jordan McQuade (2010-10-12)The interaction of tick species and the microclimate that they inhabit is a subject that is frequently studied. The known biology of the Gulf Coast tick, Amblyomma maculatum Koch (Acari: Ixodidae), was used to conduct ...
-
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 ...
-
Nielsen-Gammon, John W. (2020-08-07)This report describes the results of an extreme value analysis of precipitation in and around Harris County, Texas, in order to determine whether the newly-promulgated NOAA Atlas 14 rainfall design values are valid in a ...
-
Lalime, Michael (2010-07-14)Many processes in the ocean are interrelated. The direction with which an eddy rotates will determine if nutrients are moved closer to the surface where they can be utilized by plankton to increase the base of the food ...
-
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 ...
-
Wang, Shuguang (Texas A&M University, 2006-04-12)To investigate the generation of mesoscale gravity waves from upper-tropospheric jet-front systems, five different life cycles of baroclinic waves are simulated with a high-resolution mesoscale model (MM5 with 10-km grid ...
-
Wang, Xun (2017-07-26)In this study, we evaluate how well the Goddard Earth Observing System Chemistry Climate Model (GEOSCCM) and the Whole Atmosphere Community Climate Model (WACCM) reproduce the seasonal cycle of the tropical lower stratospheric ...
-
Viner, Kevin Carl (2011-02-22)Two problems in computational wave dynamics are considered: (i) the use of Klemp-Wilhelmson time splitting at large scales and (ii) analysis of wave-wave instabilities in nonhydrostatic and rotating mountain waves. The ...
