Title:
Smoothing and temperature extremes
Abstract: Smoothing methods are now well-established in many domains of statistics, and are increasingly used in analysis of extremal data. The talk will describe some applications of smoothing to data on temperature extremes, elucidating the relation between cold winter weather in the Alps and the North Atlantic Oscillation, and changes in the lengths of usually hot and cold spells in Britain. The work mixes classical models for extremes, generalised additive modelling, local polynomial smoothing, and the bootstrap, and is joint with Valérie Chavez-Demoulin and Mariá Süveges.
