- Abstract:
- A free-surface, global barotropic ocean model has been developed and tested at POL based on the SOC OCCAM model. This model is capable of reproducing global ocean tides and large-scale, deep ocean dynamics at high frequencies (periods up to a few months). An almost incidental benefit of this model is production of a global storm-surge model capable of reproducing barotropic dynamics around the world's shelf seas. The purpose of this proposal is to take advantage of this capability to produce and run a global storm-surge model, the Advanced Global Barotropic Ocean Model (AGBOM), for climate studies and potential operational forecasting. The main product will be three 30-year runs of the 0.25 degree model, one with real meteorological forcing for the past 30 years, and the others with simulated meteorological forcing for both the past 30 years and climate with the increasing of green house gases for the future. From these runs it will be possible to calculate statistics of extreme events and likely future changes in these statistics for the global coastline - a major focus of the next IPCC sea level chapter. The methods developed in this study will be of use to estimate the surge extremes that can be made in areas or situations (e.g., of changing climate) where no observational data exist. It can also be used further in predictions of storm surges, using atmospheric forcings derived from a cyclone model with data (e.g., supplied by the Joint Typhoon Warning Center) that would be a powerful tool towards the mitigation of disasters due to this phenomenon. In particular regions, the simulation will be further refined by coupling the AGBOM to a higher-resolution Regional Barotropic Ocean Model (RBOM). This will be used to test the importance of higher resolution and to assess the improvement produced in storm-surge forecasts in the RBOM by using the AGBOM to provide boundary conditions. Production of an interface between AGBOM and RBOM will make it possible to incorporate the AGBOM into future operational storm-surge predictions if significant improvement is found. The AGBOM run will be useful for a range of both geophysical studies (de-aliasing of satellite altimeter and gravity data, comparison with earth rotation time series, etc.), and studies of the Inverse Barometer effect and of ocean dynamics in, e.g., the Southern Ocean.
