Predicting hydrological variables is a very useful tool in water resource management. The importance of the forecast in environmental issues causes us to use more accurate statistical methods for studying the weather and climate change. The main objective of this study is to investigate the use of additive and multiplicative forms of the Holt-Winters time series model to predict environmental variables such as temperature, precipitation, and sunshine hours for one year in advance. As the Holt-Winters model uses a weighted average of current and past values to provide predictions, in this study higher emphasis is placed on the recent observations by using larger weights for these data compared to the older ones. As a case study, monthly environmental data (i.e., precipitation, maximum temperature, minimum temperature and sunshine hours) collected for a span of 30 years (from 1981 to 2010) from Robat Gharah-BilStation located in Golestan, Iran was used. After modeling the data through additive and multiplicative procedures, the main three smoothing parameters of the model are optimized using a nonlinear optimization method. Based on this study, using the multiplicative form of Holt-Winters time series results in an overall of 4% less mean absolute percentage error (MAPE) compared to the additive one. The result showed that this model is more efficient in predicting and modeling climate parameters, which show stable patterns of cycle and seasonality.
