(2011-10-31)The 2011 drought in Texas has been unprecedented in its intensity. The year 2010 had been relatively wet across most of the state, except for extreme eastern Texas. Beginning in October 2010, most of Texas experienced a ...
-
(2021-04-28)Moist processes can produce kinetic energy at subsynoptic scales, traditionally regarded as part of the -5/3 inertial subrange. Atmospheric kinetic energy cascades to both smaller and larger scales, so moist dynamics at ...
-
(2020-09-18)Low-cloud cover continues to be a dominant source of uncertainty in climate models and past observational-based studies to help constrain this uncertainty have typically been limited in both space and time or by measurements ...
-
(2018-10-09)Satellite aerosol retrievals, ground-based radar and lightning detections, and model simulations are used to study the impact of aerosols on lightning and the usefulness of knowing the aerosol state in predicting enhanced ...
-
(2013-07-30)The studies in this dissertation aim at advancing our scientific understandings about physical processes involved in the aerosol-cloud-precipitation interaction and quantitatively assessing the impacts of aerosols ...
-
(2009-05-15)Measurements of ambient volatile organic compounds (VOCs) by proton transfer reaction mass spectrometry (PTR-MS) are reported from recent airborne and surface based field campaigns. The Southeast Texas Tetroon Study (SETTS) ...
-
(2011-02-22)This research focuses on aircraft observational studies of aerosol-cloud interactions in cumulus clouds. The data were collected in the summer of 2004, the spring of 2007 and the mid-winter and spring of 2008 in Texas, ...
-
(Royal Meteorological Society, 2021-02-12)Convective system tracking was performed using 30‐min GOES‐13 infrared imagery over the Amazon region during 2014 and 2015. A total of 116,701 convective systems were identified and statistics on the probability of occurrence ...
-
(2019-11-20)The effect of SST mesoscale variability on the dynamics of the North Pacific Jet Stream and Storm track is investigated based on simulations with a global atmospheric circulation model coupled to a slab ocean model. The ...
-
(2009-05-15)Mesoscale convective vortices (MCVs), which typically form within the stratiform rain of some mesoscale convective systems (MCSs), may persist for days, often regenerating convection daily. Long-lived MCVs can produce as ...
-
(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 ...
-
(2011-08-08)In this study, the space-time relationship of precipitation fields is examined by testing the Taylor's "frozen field" hypothesis (TH). Specifically, the hypothesis supposes that if a spatio-temporal precipitation field ...
-
(2012-07-16)Two mechanisms appear to be primarily responsible for the formation of cirrus clouds in Tropical Tropopause Layer (TTL): detrainment from deep convective anvils and in situ initiation. Here we propose to identify TTL ...
-
(2013-12-10)The Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) 2A23 algorithm classifies rain echo as stratiform or convective while the 2A25 algorithm corrects vertical profiles of radar reflectivity for attenuation ...
-
(2017-06-27)Particle size and size resolved hygroscopicity distributions measured at the ARM SGP site from 2009 to 2012 were used to study new particle formation (NPF) and subsequent growth, variation in hygroscopicity and mixing state ...
-
(American Meteorological Society, 2013-04-26)The record-setting 2011 Texas drought/heat wave is examined to identify physical processes, underlying causes, and predictability. October 2010–September 2011 was Texas’s driest 12-month period on record. While the summer ...
-
(2013-04-29)A flux measurement setup was established at a communications tower north of downtown Houston, Texas, to measure energy and trace gas fluxes from a variety of emission sources in the urban surface layer. The first part of ...
-
(Texas A&M University, 2007-04-25)The Tropical Pacific Warm Pool International Cloud Experiment (TWP-ICE) took place in Darwin, Australia in early 2006. C-band radar data from this experiment were used to characterize tropical anvil areal coverage, height, ...
-
(Texas A&M University, 2005-08-29)During the summer of 2002, a modified tandem differential mobility analyzer (TDMA) was used to examine the size-resolved hydration state of the ambient aerosol in Southeast Texas. Although there were slight variations ...
-
(2012-07-16)A Discontinuous Galerkin Time Domain method (DGTD), using a fourth order Runge-Kutta time-stepping of Maxwell's equations, was applied to the simulation of the optical properties of dielectric particles in two-dimensional ...
