(Texas A&M University, 2001)This study presents a high-resolution lightning climatology for southern portions of both the Rocky Mountains and the Appalachian Mountains. Data from the National Lightning Detection Network (NLDN) are analyzed to produce ...
-
(Texas A&M University, 2001)The U. S. National Lightning Detection Network (NLDN) has recorded cloud-to-ground (CG) lightning observations regularly for more than a decade (1989-2000). The main research focus using the recorded NLDN data has been ...
-
(Texas A&M University, 2002)This study compares rain rate measurements from the Tropical Rainfall Measuring Mission (TRMM) satellite to rain rate measurements from rain gauges on open-ocean buoys. The rain gauges are part of the instrument package ...
-
(Texas A&M University, 1999)The algorithms used for the retrieval of rainfall are based on physical modeling. One of the by-products of the algorithm is an estimate of the freezing level. Using observations from the TRMM precipitation radar, we can ...
-
(Texas A&M University, 2000)The LLJ transports moisture northward from the Gulf of Mexico into the Great Plains. Proper detection of the LLJ is important in aviation and forecasting. Standard atmospheric charts are usually insufficient in properly ...
-
(Texas A&M University, 2002)The objective of this study is to document and explain the formation of a large asymmetric squall line system. Despite having a precipitation pattern similar to the conceptual model of an asymmetric squall line, the ...
-
(Texas A&M University, 2001)Photochemical oxidation of isoprene plays a significant role in tropospheric ozone production. The OH-initiated reactions of isoprene are the dominant daytime removal pathway for isoprene. The OH-isoprene reactions proceed ...
-
(Texas A&M University, 2001)The log-normal assumption for the distribution of the rain rates used for the estimation of monthly rain totals proposed in Wilheit et al 1991 was examined. Since the log-normal assumption was originally used for the SSM/I, ...
-
(Texas A&M University, 2002)TRMM Microwave Imager(TMI)-based passive microwave retrieval techniques result in biased estimates of the freezing level and rainfall over the east Pacific in the Inter Tropical Convergence Zone (ITCZ). Passive microwave ...
-
(Texas A&M University, 2002)For more than a decade, the U.S. National Lightning Detection Network (NLDN) has been recording cloud-to-ground (CG) lightning across the contiguous United States. In recent years, the focus of NLDN data analysis has been ...
-
(Texas A&M University, 2002)From June through October 2001, three Tandem Differential Mobility Analyzer (TDMA) systems were operated around Houston, Texas, to obtain a large, high-quality dataset in order to explore characteristics of aerosol size ...
-
(Texas A&M University, 2001)An investigation of the kinematic and electrical properties of the 9-10 June, 1998 Red River Mesoscale Convective System (MCS), as observed by the NOAA P3 Tail Radar and the National Lightning Detection Network, is presented. ...
-
(Texas A&M University, 2000)Kinetic studies of the isoprene oxidation reactions initiated by the hydroxyl radical OH and the chlorine atom Cl have been investigated using a fast-flow reactor in conjunction with chemical ionization mass spectrometry ...
-
(Texas A&M University, 2002)Over the past decade, ensemble forecasting has emerged as a powerful tool for numerical weather prediction. Not only does it produce the best estimate of the state of the atmosphere, it also could quantify the uncertainties ...
-
(Texas A&M University, 2003)An evaluation of the COMMAS (COllaborative Model for Multiscale Atmospheric Simulation) model's ability to simulate the dynamics and microphysics of a multicellular storm was conducted using data from the 19 September storm ...
-
(Texas A&M University, 2001)Current physically-based Radiative Transfer Model (RTM) algorithms for estimating oceanic rain use a very simplified hydrometeor profile that ignores the mixed-phase regions (Wilheit et al., 1977). However, to estimate ...
-
(Texas A&M University, 2001)Nitrogen oxides (NOx) play an important role in atmospheric chemistry. High tropospheric NOx concentrations increase ozone (O₃) levels via photochemical cycling of NO to NO₂, whereas low NOx concentrations result in the ...
-
(Texas A&M University, 2001)Weather forecasters have had difficulty forecasting mesoscale precipitation bands occurring in the regions of frontal zones. Within the last twenty years, slantwise convection (SC) through the release of conditional ...
-
(Texas A&M University, 2000)A climate database for the state of Texas has been created from daily observations made at 1336 stations throughout Texas. These stations consist of both fest-order stations and local cooperative weather stations. The ...
-
(Texas A&M University, 2000)The performance of the Damaging Downburst Prediction and Detection Algorithm (DDPDA) was evaluated for bow echo storm systems using a database of more than 1800 radar volume scans covering more than 150 hours of observations ...
