Changes in synoptic weather patterns in the polar regions in the twentieth and twenty-first centuries. Part 1: ArcticCassano, J.J., P. Uotila, and A.H. Lynch 2006, International Journal of Climatology, 26, 1027-1049. DOI: 10.1002/joc.1306 An analysis of late twentieth and twenty-first century predictions of Arctic circulation patterns in a ten-model ensemble of global climate system models, using the method of self-organizing maps (SOMs), is presented. The model simulations were conducted in support of the fourth assessment report of the intergovernmental panel on climate change (IPCC). The analysis demonstrates the utility of SOMs for climate analysis, both as a tool to evaluate the accuracy of climate model predictions, and to provide a useful alternative view of future climate change.
