A dynamic model for short-scale rainfall disaggregation

Abstract

The single-site dynamic disaggregation model developed and presented in this paper is a generalized step-by-step approach to stochastic disaggregation problems. The forms studied concern low-level variables with Markovian structure and normal or gamma marginal distributions. Combined with a rainfall model, the disaggregation scheme gives a rainfall generator transforming monthly rainfall into events and hourly amounts. A particular application of the generator, based on historical data, is used to illustrate and test the model. © 1990 Taylor and Francis Group, LLC.
