Statistics, Temperatures and Climate Change

Peter Guttorp


University of Washington - Department of Statistics

We look for trends in a network of synoptic temperature stations in south central Sweden. The daily data are analyzed using a model that combines long and short memory, seasonal effects on both mean and variance, and a wavelet-based approach to semiparametric estimation of trend. Using results from the fourth assessment report of IPCC we expect to see a stronger signal in annual minima, and we develop a hierarchic Bayesian approach to model the climatic aspects of these data.
