Stochastic modelling of daily precipitation for Canada

Multisite downscaling of daily precipitation with a stochastic weather generator

Stochastic models of daily precipitation are useful both for characterizing different precipitation climates and for stochastic simulation of these climates in conjunction with agricultural, hydrological, or other response models. A simple stochastic precipitation model is used to downscale— i.e. disaggregate from area-average to individual station—precipitation statistics for 6 groups of 5 U.S...

A Semi-Parametric Stochastic Model For Simultaneous Stochastic Simulation Of Daily Precipitation Amounts At Multiple Sites

EXTENDED ABSTRACT A semi-parametric stochastic model for generation of daily precipitation amounts, simultaneously at a collection of stations in a way that preserves realistic spatial correlations, accommodates seasonality, and reproduces a number of key aspects of the distributional and dependence properties of observed rainfall is described and illustrated. Following a conventional weather g...

Stochastic Description of Precipitation

Conditioning stochastic properties of daily precipitation on indices of atmospheric circulation

The relationship between precipitation and large-scale measures of atmospheric circulation has received much attention in recent years (e.g. Bardossy & Caspary, 1990; Bardossy & Plate, 1992; Hughes et al., 1993; Woolhiser et al., 1993; Katz & Parlange, 1993). Some of the interest relates to quantifying the possible change in atmospheric circulation within the past two decades, with associated c...
