Research area

• Numerical modeling of atmospheres and oceans with particular emphasis on paleoclimate modeling.
• Unravelling the dynamical connections linking ENSO and the south Asian monsoon.
• The role of baroclinic instability of the East African jet in spawning hurricanes.
• The history of ENSO in the Quaternary
• The dynamical history of the tropical Pacific thermocline
• Initiation and maintenance of glaciation
• Atmosphere-Ice interactions

Research interest

Dr. Bush specializes in the numerical modeling of atmospheres and oceans with particular emphasis on paleoclimate modeling. Ongoing research includes the use of a coupled atmosphere-ocean general circulation model to investigate the impact of orbital parameters on the coupled system, the maintenance of the equatorial thermocline, and the roles that such coupled phenomena as El Nino have played in the paleoclimates of Earth's history. Another area of interest includes the simulation of glaciation during periods of enhanced atmospheric carbon dioxide (such as the Ordovician) as well as during periods of reduced atmospheric carbon dioxide (such as the Last Glacial Maximum). Dr. Bush is a Fellow in the Canadian Institute for Advanced Research's (http://www.ciar.ca) Earth System Evolution Program and is involved in the Polar Climate Stability Network, the Western Canadian Cryospheric Network, and the Baikal Archeology Project.

Research opportunity

I would be very interested to supervise graduate students in the following areas:

• unravelling the dynamical connections linking ENSO and the south Asian monsoon
• the role of baroclinic instability of the East African jet in spawning hurricanes
• the history of ENSO in the Quaternary
• the dynamical history of the tropical Pacific thermocline
• initiation and maintenance of glaciation
