Cloud condensation nuclei measurements during the 2010 CalNex campaign: observations, analysis and impacts
(Georgia Institute of Technology, 2013)
Direct sensitivity techniques in regional air quality models: development and application
(Georgia Institute of Technology, 2013-10-04)
Sensitivity analysis based on a chemical transport model (CTM) serves as an important approach towards better understanding the relationship between trace contaminant levels in the atmosphere and emissions, chemical and ...
Intraseasonal variability of summer convection over South America
(Georgia Institute of Technology, 2013-10-23)
In other regions of the world, intraseasonal variations of precipitation have been used to extend the range of weather and hydrological forecasts especially during the rainy monsoon season. This intraseasonal variability ...
Microphysical processes of volcanic ash aggregation and their implications for volcanic eruption dynamics
(Georgia Institute of Technology, 2013-08-20)
Although numerous hazard models exist to assess possible ash fallout from explosive volcanic eruptions around the world, these models frequently neglect to consider ash aggregation or use a simple percent proxy to represent ...
Understanding the scale interaction of atmospheric transient disturbances and its coupling with the hydrological cycle over the Pacific-North American regions
(Georgia Institute of Technology, 2013-07-08)
Large-scale atmospheric disturbances play important roles in determining the general circulation of the atmosphere during the North Pacific boreal winter. A number of scientific questions have been raised due to these ...
The variability and seasonal cycle of the Southern Ocean carbon flux
(Georgia Institute of Technology, 2013-07-03)
Both physical circulation and biogeochemical characteristics are unique in the Southern Ocean (SO) region, and are fundamentally different from those of the northern hemisphere. Moreover, according to previous research, ...
On the representation of sub-grid scale phenomena and its impact on clouds properties and climate
(Georgia Institute of Technology, 2013-11-18)
This thesis addresses a series of questions related to the problem of achieving reliable and physically consistent representations of aerosol-cloud interaction in global circulation models (GCM). In-situ data and modeling ...
Submesoscale dynamics and transport properties in the Gulf of Mexico
(Georgia Institute of Technology, 2013-11-18)
Submesoscale processes, characterized by O(1km) horizontal scale and O(1) Rossby number, are ubiquitous in the world ocean and play an important role in the vertical flux of mass, buoyancy and tracers in the upper ocean. ...
Chemical and optical properties of organic aerosols in the atmosphere over continental US: formation, partitioning, and light absorption
(Georgia Institute of Technology, 2013-11-18)
The chemical and optical properties of particulate organic compounds remain unclear, which leaves large uncertainties in the estimation of global radiative transfer balance. Gas and find particle (PM2.5) phase formic acid ...
Understanding an evolving diffuse plate boundary with geodesy and geochronology
(Georgia Institute of Technology, 2013-11-11)
Understanding spatial and temporal variations in strain accumulation and release along plate boundaries is a fundamental problem in tectonics. Short-term and long-term slip rates are expected to be equal if the regional ...
