Abstract
The Box-Jenkins methodology of time series analysis is considered one of the most important predictive models. These models are characterized by high accuracy and flexibility in their diagnosis and description of the future climate phenomena and variables. In this paper the Box-Jenkins methodology has been applied to analyze the average monthly climate data for Tripoli area which are located at Libyan northwestern. The considered data represent monthly data observed the period (1961-2003) inclusive. Specialized software has been used for data analysis. After comparison processes among several different standard models that belong to ARIMA models it has been observed that the SARIMA(1,0,5)(0,0,2)12 model is most appropriate and efficient to predict the monthly temperatures. According to the estimation results using this model, the monthly temperature of Tripoli area were predicted for the period from January 2004 to December 2005. The predicted values of the monthly temperature have shown to be consistent with those of the original series.
