Earth’s
integrated climate system encompasses non-linear interactions between the land
surface, oceans, and atmosphere. Many of the physical mechanisms influencing
the variability within this system remain poorly understood. My current research
focuses on understanding processes that govern climate variability by investigating
feedbacks between extreme, transient events and the mean climate state.
Working with Matthew Huber, my research has centered on explaining the role of tropical cyclones within the climate system by exposing potential feedbacks between extreme winds, surface temperature, and upper ocean vertical mixing. The climate system is very sensitive to vertical mixing in the upper tropical oceans, which affects the surface energy budget, triggers primary productivity, and contributes to sustaining and regulating the meridional overturning circulation and heat transport. Sources of the mixing remain poorly understood, and a realistic representation is lacking from the current generation of climate models. Tropical cyclones are extreme, transient events that efficiently mix the upper tropical oceans. These events may provide a fundamental, climate-sensitive mixing mechanism that act as a thermostat for the tropics, thereby buffering these regions to warming while amplifying the effects of climate change at high latitudes (consistent with past warm climates).
Through data analysis and climate modeling, my PhD program focuses on understanding the role of tropical cyclones within the Earth's climate system by examining these events a possible source of climate-sensitive vertical ocean mixing in the upper tropical oceans.
Purdue-based portal for NCAR's Community Climate System Model (CCSM)
The following link accesses a Purdue-based web portal to a “community” installation of the National Center for Atmospheric Research (NCAR) Community Climate System Model (CCSM) using TeraGrid resources. CCSM simulates Earth’s climate system by combining comprehensive models of the atmosphere, ocean, sea-ice, and land surface. The Purdue CCSM portal allows users easy access to this world class, fully-coupled climate model through an intuitive and easy to use web interface. This work is part of an ongoing collaborative effort between Information Technology at Purdue (ITAP) and the Department of Earth and Atmospheric Sciences.
Paleoclimate CCSM model simulations
The following CCSM links provide information about running NCAR's latest version of the Community Climate System Model, CCSM3.0. These pages are meant to assist new users in learning how to set up the model using idealized land configurations different from present day. This work is part of an ongoing effort supported by an NSF SGER grant which began in the summer of 2004.
