Differences in Ice Cloud Optical Depth from CALIPSO and Ground-Based Raman Lidar at the ARM SGP and TWP Sites
Ice cloud column optical depths from the Cloud-Aerosol Lidar and Infrared Pathfinder Satel- lite Observations (CALIPSO) satellite and ground-based Raman lidars (RLs) at the Atmo- spheric Radiation Measurement (ARM) Southern ... -
Diurnal Cycles of Synthetic Microwave Sounding Lower-Stratospheric Temperatures from Radio Occultation Observations, Reanalysis, and Model Simulations
An observationally-based global climatology of the temperature diurnal cycle in the lower stratosphere is derived from eleven different satellites with Global Positioning System-Radio Occultation (GPS-RO) measurements from ... -
The downstream decay of trapped lee waves
The mechanisms through which trapped lee waves decay, and where this decay occurs, are of utmost importance in order to understand the impact that these waves have on the larger-scale climate system. Previous studies have ... -

Dynamic and Thermodynamic Controls on the Amount and Distribution of Orographic Precipitation
This thesis examines various mechanisms controlling the amount and distribution of precipitation in mountainous terrain. In Chapter 2, linear theory and numerical simulations are used to investigate how the tropopause ... -
The dynamics of gap flow over idealized topography
(2002)A flow past an idealized topography with a narrow gap is examined using a numerical model. The obstacle is a finite ridge in the N-S direction with a narrow gap in the W-E direction and the fluid has a simple vertical ... -
Dynamics of Large-Scale Convective Onset in the Madden-Julian Oscillation
The role of large-scale circulation anomalies in the convective onset of the Madden-Julian Oscillation (MJO) over the Indian Ocean during the Dynamics of the Madden-Julian Oscillation (DYNAMO) field campaign, conducted ... -
The effect of rain on microwave backscatter from the ocean: measurements and modeling
(2004)Microwave backscatter is used to probe the atmosphere, ocean, and land surface. The SeaWinds scatterometer on QuikSCAT and the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) are both microwave instruments ... -
Effect of snow grain shape and impurities on snow albedo and its parameterization: China, North America, and the Arctic
Snow cover is important for Earth’s surface energy budget, primarily because the surface reflectance (albedo) is greatly increased if covered by a layer of snow. A correct estimation of snow albedo is therefore crucial for ... -
Effective mesoscale, short-range ensemble forecasting
(2003)This study developed and evaluated a short-range ensemble forecasting (SREF) system with the goal of producing useful forecast probability ( FP). Real-time, 0 to 48-h forecasts from four different SREF systems were compared ... -
The Effects of Ice Crystal Shape on the Evolution of Optically Thin Cirrus Clouds in the Tropics
Thin cirrus clouds in the tropical tropopause layer (TTL) play potentially important roles in Earth’s radiation budget and in the transport of water into the stratosphere. Radiative heating of these clouds results in ... -
The effects of meridional heating gradients on the atmospheric general circulation and its variability
(2005)We use a simple GCM to investigate two aspects of the general circulation of the atmosphere. First, we investigate the effects of zonal jet structure on the leading mode of variability in the Northern Hemisphere. Model ... -
Emission, evolution, and radiative properties of particles from biomass burning in Brazil
(1998)In this dissertation measurements of the physical, chemical, and radiative properties of biomass-burning particles, obtained by the Cloud and Aerosol Research Group (CARG), Department of Atmospheric Science, are described ... -
Emissions and Chemistry of Reactive Nitrogen in Wildfire Plumes
Wildfires are an important source of reactive nitrogen species to the atmosphere, accounting for approximately 25% of global annual nitrogen oxides (NOx). Emissions of wildfires are highly variable depending on factors ... -
Emissions from savanna fires in southern Africa
(2004)Airborne measurements are presented of emissions from savanna fires in southern Africa during the dry season. Measurements were obtained aboard the University of Washington Convair-580 research aircraft during the SAFARI ... -
An empirical study of the lidar ratio and its variability, with implications for determining climate forcing by satellite-borne lidar
(2001)It is well-established that atmospheric aerosols play a role in determining the radiative balance of the Earth. Further, it is believed that anthropogenic aerosols may be causing significant cooling at the Earth's surface ... -
Empirically Derived Sensitivity of Vegetation to Climate Across the Globe
To predict the response of vegetation to climate change, we must understand the physiological processes controlling productivity across large spatial scales, encompassing global climate space. To date there is not a fully ... -
The Energetic Constraints on the Zonal Mean Atmospheric Circulations in the Tropics, Midlatitudes, and High Latitudes
(2013-07-25)In this doctoral thesis, I have studied the processes that affect the atmospheric energy budget and their coupling relationships with atmospheric circulations. The equator-to-pole radiation gradient at the top of the ... -
Energy and Moisture Transport in the Earth Climate System: Mean State and the Perturbation Response
Four studies are presented which investigate how energy and moisture transport define the mean state of the Earth Climate System and its response to perturbations. In the first study, we use a global climate model to study ...
