Abstract


The objective of this paper is to investigate the short and long run association, and causality among precipitation (dependent variable), and other climate parameters such as minimum and maximum temperature, wind speed, relative humidity, and atmospheric pressure (independent variables) for Islamabad city. The authors have considered the data set from July 2001 December 2017, and applied several econometrics techniques such as Augmented Dickey-Fuller, Vectors Auto regression, Multivariate cointegration, and Granger causality techniques to analyze the data. The findings of the study demonstrated a longterm association between precipitation, and minimum temperature, atmospheric pressure, relative humidity, and wind speed. Finally, the Granger causality revealed the one-way causal relationship from atmospheric pressure to the rainfall, rainfall to relative humidity, and atmospheric pressure to rainfall. However, the authors have observed two-way causality between precipitation and minimum temperature.
