Examination of Temperature Variability over Lahore (Pakistan) and Dhaka (Bangladesh): A Comparative Study

Abstract

 Lahore and Dhaka are rapid expanding and over populated cities of South Asia located in Pakistan and Bangladesh respectively. The present study focuses on the evaluation of temperature variability in comparison of both cities. This study primarily aims at the assessment and examination of temperature variations in both mega cities of South Asia which are seasonal as well as the annual. The time series data were analysed by using statistical techniques Autoregressive Moving Average Model (ARMA) and Autoregressive Integrated Average Model (ARIMA). The results reveal that the minimum temperature is increasing much faster than that of the maximum temperature of both cities. However, the temperature rise(in maximum and minimum) has been observed highest during the spring seasons in both cities.
