Abstract

This paper presents an overview of the observed behavior of the UPLB rainfall from 1959-2008 through neural networks approach. A 50 year daily rainfall data, daily mean temperature, daily relative humidity and daily sunshine duration was obtained from the Agrometeorology and Farm Structure Division, College of Engineering and AgroIndustrial Technology. This study introduces the effect of forecasting UPLB rainfall by the conventions in most of the Neural Network studies based on three different time horizons; 1) the 366 days basis, 2) days in a month basis, and 3) monthly basis. A nonlinear function was approximated showing rainy season from the month of June to November and dry season throughout the rest of the year. The days in a month basis showed that Neural Network performed better in forecasting dry season than rainy season. The monthly basis forecast performed best with almost the same peaks as the actual values.
