Abstract
The teleconnection patterns associated with interannual variability, and the El Nino Southern Oscillation in particular, are likely to have been different in the past when topographic forcing by massive continental ice sheets altered the climatological planetary wave field. Numerical models may be able to assist in reconstructing what these teleconnection patterns were and how proxy data records should be interpreted. In this talk, we discuss simulated ENSO teleconnection patterns from the Last Glacial Maximum to today and demonstrate using a coupled atmosphere-ice sheet general circulation model that millenial-scale ice dynamics may have been influenced by the teleconnection patterns of interannual variability, particularly during ice sheet inception and demise.
