Intraseasonal Dynamical Evolution of the Northern Annular Mode
(Georgia Institute of Technology, 2005-04-21)
Recent observational and modeling studies indicate a robust dynamical coupling between the stratosphere and troposphere during boreal winter. This coupling occurs in association with the Northern Annular Mode (NAM), which ...
Interrelationships Among Large-Scale Atmospheric Circulation Regimes and Surface Temperature Anomalies in the North American Arctic
(Georgia Institute of Technology, 2004-07-08)
The focus of this study is to examine the mechanisms involved in the interactions among large-scale atmospheric circulation patterns and how they are related to surface air temperature anomalies in the North American Arctic. ...
Variability of the South Pacific Convergence Zone and its influence on the general atmospheric circulation
(Georgia Institute of Technology, 2007-11-15)
Intense atmospheric convection associated with the South Pacific Convergence Zone (SPCZ) significantly impacts basin-scale circulation patterns over the Pacific. We explore dynamical processes which foster changes in ...
Diagnostic studies of extratropical intraseasonal variability in the northern hemisphere
(Georgia Institute of Technology, 2006-04-11)
A comprehensive analysis of midlatitude intraseasonal variability in extended integrations of General Circulation Models (GCMs) developed at the National Aeronautics and Space Administration Goddard Space Flight Center is ...
Predictability and prediction of tropical cyclones on daily to interannual time scales
(Georgia Institute of Technology, 2012-07-03)
The spatial and temporal complexity of tropical cyclones (TCs) raises a number of scientific questions regarding their genesis, movement, intensification, and variability. In this dissertation, the principal goal is to ...
Climate dynamics of the South Pacific Convergence Zone and similarities with other subtropical convergence zones in the Southern Hemisphere
(Georgia Institute of Technology, 2010-11-15)
Three semi-permanent cloud bands exist in the Southern Hemisphere extending southeastward from the equator, through the tropics, and into the subtropics. The most prominent of these features occurs in the South Pacific and ...
A simple zonal average energy budget model of the earth-atmosphere system
(Georgia Institute of Technology, 1989-12)
Temporal variations of monsoon systems
(Georgia Institute of Technology, 2010-09-09)
It has been proposed that the Asian-Australasian monsoon system is influenced by large-scale sea-surface temperature (SST) variability in the three tropical oceans although how this influence is manifested has remained a ...
On the uncertainties and dynamics of Pacific interannual and decadal climate variability and climate change
(Georgia Institute of Technology, 2010-11-11)
Tropical and extratropical Pacific decadal climate variability substantially impact physical and biological systems in the Pacific Ocean and strongly influence global climate through teleconnection patterns. Current ...
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 ...
