Comparision of several downscaling methods of rainfall in Ca river basin under climate change

Abstract

      Climate change is an challenge problem worldwide. Climate change is simulated by a number of Global Climate Models (GCMs) which have very coarse resolution. Downscaling methods are used to simulate rainfall more details. Weather generation and Transfer function are typical downscaling methods and have been successfully applied to many areas in the world. This paper compares these two methods of downscaling daily rainfall series at 12 stations across Ca basin based on global climate model HadCM3.
