1 Garrett, Timothy J.Are there basic physical constraints on future anthropogenic emissions of carbon dioxide?Global Circulation Models (GCMs) provide projections for future climate warming using a wide variety of highly sophisticated anthropogenic CO2 emissions scenarios as input, each based on the evolution of four emissions "drivers": population p, standard of living g, energy productivity (or efficiency...Global circulation models; Anthropogenic carbon dioxide emissions2009
2 Reichler, Thomas J.Breaking down the tropospheric circulation response by forcingThis study describes simulated changes in the general circulation during the twentieth and twenty -first centuries due to a number of individual direct radiat ive forcings and warming sea surface temperatures, by examining very long time-slice simulations created with an enhanced version of the Geop...2012-01-01
3 Steenburgh, William JamesClimate change and Utah: the scientific consenusThis report, entitled \"Climate Change and Utah: The Scientific Consensus\" was prepared for Utah Governor Jon Huntsman Jr. under the direction of his Blue Ribbon Advisory Council on Climate Change (BRAC). It summarizes current (2007) scientific understanding of climate change and its potential imp...Climate, Climate Change, Utah2007-09
4 Horel, John D.The climatology of synoptic-scale ascent over Western North America: a perspective on storm tracksThe position and variability of storm tracks across western North America are examined during the October-April cool seasons spanning 1989-2010. The location and intensity of storms are represented by strong synoptic-scale ascent, which is diagnosed by the alternative balance omega equation applied ...2012-01-01
5 Reichler, Thomas J.Determining the tropopause height from gridded dataA method is presented to determine tropopause height from gridded temperature data with coarse vertical resolution. The algorithm uses a thermal definition of the tropopause, which is based on the concept of a threshold lapse-rate. Interpolation is performed to identify the pressure at which this th...Meteorology and Atmospheric Dynamics: Stratosphere/troposphere interactions; Numerical modeling and data assimilation; Meteorology; Atmospheric Dynamics: General circulation2003
6 Steenburgh, William JamesEpisodic dust events of Utahs Wasatch Front and adjoining regionEpisodic dust events cause hazardous air quality along Utah's Wasatch Front and dust loading of the snowpack in the adjacentWasatch Mountains. This paper presents a climatology of episodic dust events of the Wasatch Front and adjoining region that is based on surface weather observations from the Sa...2012-01-01
7 Reichler, Thomas J.Expansion of the Hadley cell under global warmingA consistent weakening and poleward expansion of the Hadley circulation is diagnosed in the climate change simulations of the IPCC AR4 project. Associated with this widening is a poleward expansion of the subtropical dry zone. Simple scaling analysis supports the notion that the poleward extent of ...Hadley cell; Climate change; Subtropical dry zone2007
8 Garrett, Timothy J.Fall speed measurement and high-resolution multi-angle photography of hydrometeors in free fallWe describe here a new instrument for imaging hydrometeors in free fall. The Multi-Angle Snowflake Camera (MASC) captures high-resolution photographs of hydrometeors from three angles while simultaneously measuring their fall speed. Based on the stereoscopic photographs captured over the two months ...2012-01-01
9 Steenburgh, William JamesFinescale orographic precipitation variability and gap-filling radar potential in Little Cottonwood Canyon, UtahFinescale variations in orographic precipitation pose a major challenge for weather prediction, winter road maintenance, and avalanche forecasting and mitigation in mountainous regions. In this investigation, ground based X-band radar observations collected during intensive observing period 6 (IOP6)...2014-01-01

11 Steenburgh, William JamesGreat Salt Lake-effect precipitation: observed frequency, characteristics, and associated environmental factorsThis climatology examines the environmental factors controlling the frequency, occurrence, and morphology of Great Salt Lake-effect (GSLE) precipitation events using cool season (16 September-15 May) Weather Surveillance Radar-1988 Doppler (WSR-88D) imagery, radiosonde soundings, and MesoWest surfac...2012-01-01
12 Horel, John D.Idealized large-eddy simulations of sea and lake breezes: sensitivity to lake diameter, heat flux and stabilityIdealized large-eddy simulations of lake and sea breezes are conducted to deter mine the sensitivity of these thermally-driven circulations to variations in the land-surface sensible heat flux and initial atmospheric stability. The lake-breeze and sea-breeze metrics of horizontal wind speed, horizon...2012-01-01
13 Garrett, Timothy J.Modes of growth in dynamic systemsRegardless of a system's complexity or scale, its growth can be considered to be a spontaneous thermodynamic response to a local convergence of down-gradient material flows. Here it is shown how system growth can be constrained to a few distinct modes that depend on the time integral of past flows a...2012-01-01
14 Garrett, Timothy J.No way out? the double-bind in seeking global prosperity alongside mitigated climate changeIn a prior study (Garrett, 2011), I introduced a simple economic growth model designed to be consistent with general thermodynamic laws. Unlike traditional economic models, civilization is viewed only as a well-mixed global whole with no distinction made between individual nations, economic sectors,...2012-01-01
15 Garrett, Timothy J.Novel basis for interpreting recent acceleration of anthropogenic carbon dioxide emissionsThis paper presents a simple thermodynamic model for understanding economic and carbon dioxide emissions growth.Thermodynamics; economics; climate; growth2008
16 Garrett, Timothy J.Observed influence of riming, temperature, and turbulence on the fallspeed of solid precipitationForecasts of the amount and geographic distribution of snow are highly sensitive to a model's parameterization of hydrometeor fallspeed. Riming is generally thought to lead to particles with a higher mass and terminal velocity. Yet models commonly assume that heavily rimed particles such as graupel ...2014-01-01
17 Jenkins, Alyssa MarieObserving snow and wind: using the environment to engage students in science and engineeringThis study focused on the effectiveness of new curriculum that was integrated with hands on environmental instrumentation and student learning. The goals of this study were to increase student proficiency with environmental instrumentation, as well as enhance student confidence to use technologies t...Science, learning, hands on, environment, new curriculum2011
18 Reichler, Thomas J.Role of boundary and initial conditions for dynamical seasonal predictabilityThe importance of initial state and boundary forcing for atmospheric predictability is explored on global to regional spatial scales and on daily to seasonal time scales. A general circulation model is used to conduct predictability experiments with different combinations of initial and boundary co...Atmospheric predictions; seasonal forecasting; boundary forcing2002
19 Reichler, Thomas J.; Kim, JunsuUncertainties in the climate mean state of global observations, reanalyses, and the GFDL climate modelClimate research relies on realistic atmospheric data over long periods of time. Global reanalyses or observations are commonly used for this type of work. However, the many problems associated with both the reanalyses and observations cast doubts on the reliability of such data for climate appli...Climate; atmospheric data; reanalyses2008
20 Reichler, Thomas J.; Staten, Paul W.Use of radio occultation for long-term tropopause studies: uncertainties, biases, and instabilities.Research suggests that changes in tropopause structure can both indicate and impact changes in the global climate system.
