Monsoon rainfall forecasting in Sri Lanka using artificial neural networks

Abstract

Rainfall is a complex process and forecasting rainfall is complicated because it involves a lot of parameters but precise rainfall forecasting is necessary for many human activities. Even though considerable research work has been done in rainfall prediction, comparatively fewer efforts have been made on Sri Lankan monsoon rainfall prediction using large scale climatic teleconnections. In this paper, results of a study in investigating the appropriateness of artificial neural networks in forecasting monsoon rainfall in Sri Lanka using large scale climate teleconnections is presented.
