Description:
A stochastic model is described that allows transfer of information from general circulation models to precipitation gauge locations using a weather state classification scheme. he weather states, which are based on present and previous day's sea level pressure, are related stochastically to gauge daily precipitation and temperature. eather states are defined to give maximal separations of test station precipitation distributions using the Classification and Regression Trees procedure. 0-year sequence of simulated precipitation and temperature is used to estimate seasonal streamflows and flood frequency distributions under present and doubled CO2 climates.
