Abstract

A stochastic simulation model of daily rainfall in discrete time is proposed. The model simulates the sequence of rainfall occurrences using the method of transition probability matrices. Synthetic daily rainfall depths are then generated using sampling methods plus a two step power transformation scheme (TSPT). Rainfall data from four meteorological stations from the islands Rhodes and Chios (Aegean Sea) were used for model validation. The proposed model was also compared to a widely used TPG model. Results showed that the proposed model performed more satisfactorilly than the TPG model preserving the statistical characteristics and the total number of rainfall occurrences of the historical samples.
