摘要：

The paper presents a multidimensional model of nonstationary space-time rainfall over a catchment due to a single storm event. The model is based on a conceptual representation of the essential features of an extratropical cyclonic storm. The storm is assumed to consist of a hierarchy of scales of which the smallest are the rain cells which are embedded within the small mesoscale areas, which are then embedded within the large mesoscale area or rainband. The mean and nonstationary space-time covariance are derived for the conceptual rainfall model. In addition, the statistics and stochastic dependence structures of rainfall intensity aggregated or averaged over finite times and finite areas are also derived.
