Abstract
Climate change is a global phenomenon but its implications are distinctively local. The climatic variables include temperature, rainfall, humidity, wind speed, cloud coverage, and bright sunshine. The study of behavior of the climatic variables is very important for understanding the future changes among the climatic variables and implementing important policies. The problem is how to study the past, present, and future behaviors of the climatic variables. The purpose of the present study was to develop an appropriate vector autoregression (VAR) model for forecasting monthly temperature, humidity, and cloud coverage of Rajshahi district in Bangladesh. The test for stationarity of the time series variables has been confirmed with augmented Dickey–Fuller, Phillips–Perron, and Kwiatkowski–Phillips–Schmidt–Shin tests. The endogenity among the variables was examined by F-statistic proposed by C.W.J. Granger. The order of the VAR model was selected using Akaike information criterion, Schwarz information criteria, Hannan–Quinn information criteria, final prediction error, and likelihood ratio test. The ordinary least square method was used to estimate the parameters of the model. The VAR(8) model was found to be the best. Structural analyses were performed using forecast error variance decomposition and impulse response function. These structural analyses divulged that the temperature, humidity, and cloud coverage would be interrelated and endogenous in future. Finally, temperature, humidity, and cloud coverage were forecasted from January 2011 to December 2016 using the best selected model VAR(8). The forecasted values showed an upward trend in temperature and humidity and downward trend in cloud coverage. Therefore, we must show our friendly behavior to the environment to control such trends.
