The Impacts of the Indian Ocean warming trend on African Climate. Dan Hodson and Rowan Sutton NCAS Centre for Global Atmospheric Modelling Department of Meteorology University of Reading
Outline Observations. Experiments I –Atmosphere model forced with: Historical Observed Sea Surface Temperatures. 1°C Anomaly in the Indian Ocean Indian Ocean Temperature Trend Experiments II –Atmosphere model force with Observed Indian Ocean warming Trend Results Conclusions and Caveats
Conclusions AGCMs forced with warm Indian Ocean capture some of the trends in African rainfall (both FMA and JAS). Trends associated with changes in subsidence/ changes in Walker Circulation. Can we use AGCMs to model past changes in this way?
