Centiennal Scale Southern Annular Mode Behavior

PI: Ryan Fogt
Institution: Ohio State University
We will be examining the Southern Annular Mode (SAM) from the IPCC AR4 archive from 1850 - 2005 and comparing climate model simulations of the SAM to instrument-based reconstructions. The work compliments the recent study of Miller et al. (2006) published in the Journal of Geophysical Research. We are planning on submitting the work to Journal of Climate in the near future.

The work will be conducted primarily by myself and colleagues at The Ohio State University. I will also be continuing this research at a post-doctoral position housed at the NOAA Earth System Research Laboratory (ESRL) starting in September. There I will investigate specifically the impact of depleting polar stratospheric ozone on the SAM trends.
