Adventures in dynamical downscaling

This talk will focus on our approaches to dynamically downscale global model simulations of past and future climate. Based on our interest in locally severe thunderstorms, we have developed a downscaling procedure that involves a multi-decadal sequence of daily integrations of the Weather Research and Forecasting model, performed at relatively high resolution (gridpoint spacings of a few kilometers). Advanced statistical methods are used to identify and classify the severe convective weather in the model output. The various technical challenges that we have encountered will be described.
