Improved Regional Climate Change Projections Through Dynamical Downscaling

By modeling the atmosphere at a much finer scale than is possible using a coupled GCM we can more accurately capture the processes that operate on Tasmania’s weather/climate at the regional level and thus can more clearly answer the question of how Tasmania’s climate will change in the future. We present results that show the improvements in resolving the local-scale climate and climate drivers with increasing resolution that can be achieved through downscaling, when compared to a gridded observational data set (AWAP).
