Overview

About

Dr. Bush specializes in the numerical modeling of atmospheres and oceans with particular emphasis on paleoclimate modeling. On-going 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 Niño 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

Computer simulation and videos are used to illustrate how the weather systems work. Prerequisite: Any 100-level Science course. [Faculty of Science]

Winter Term 2021
EAS 270 - The Atmosphere

An introduction to weather. Atmospheric composition, vertical structure and energetics. Humidity and clouds, stratification and instability. Atmospheric motion on the global and synoptic scales. Air masses, fronts and storms. Introduction to weather maps, weather analysis and numerical weather prediction models. Weather map discussions. Prerequisite: Any 100-level Mathematics or Physics course, or SCI 100.

Fall Term 2020
EAS 373 - The Climate System

An examination of the physical processes influencing global climate. Radiation and energy in the climate system, the hydrological cycle, general circulation of the atmosphere and ocean, climate feedback mechanisms, climate history and climate change, introduction to climate models. Prerequisite: EAS 270. Not available to students with credit in EAS 271. [Faculty of Science]
