BAMOS Special Issue Ocean forecasting: a grand challenge that is delivering on its promise Gary Brassington Bureau of Meteorology The goal to forecast the chaotic ocean was first proposed by the US Navy in the mid-80’s. Ocean forecasting has now matured to the point that skilful forecasts are having a measurable impact on societal applications including defence, search and rescue and offshore industries. New advances in our science will extend this capability and its impact over the next decade. The latest thinking on extreme sea levels for coastal planning Kathy McInnes CSIRO Marine and Atmospheric Research Storm surges and oceanic waves are the major cause of extreme sea levels and devastating coastal impacts along coastlines. The coastal impact of storm surges and waves will continue to increase under rising sea levels, while projected changes in global atmospheric circulation and weather patterns on interannual to climate change time scales may further influence likelihoods of severe storm surges and waves through changes to the frequency, intensity and location of severe weather events. Understanding such changes at the regional to coastal scale is essential for robust coastal planning and adaptation. Progress towards understanding wave and storm surge climates and their combined contribution to extreme sea levels in the context of a changing climate was presented. 25
