Analysis of Climate Change Using Temperature and Rainfall Anomalies and Diurnal Temperature Ranges
Main Article Content
Abstract
The problem of climate change is worldwide and causing diverse effects on all aspects of life. Altering rain patterns could cause floods in certain areas and droughts in the other causing a direct threat to our food security. This study was conducted to analyze different indicators of climate change in three cities of Punjab Province of Pakistan (Lahore, Faisalabad and Multan). Secondary data was collected from Pakistan Meteorological Department. Study parameters were minimum temperature, maximum temperature, annual rainfall and diurnal temperature rainfall. Results showed that minimum temperature anomaly decreased during most of the years from 1977 to 1998. 10-years moving average of minimum temperature anomaly remained negative till early 21st century for Lahore, Faisalabad and Multan. Afterwards, 10-years moving average of minimum temperature anomaly increased gradually and became positive. Maximum DTR was 1.75, 2.0 and 1.50 for Lahore, Faisalabad and Multan, respectively. A great variation in annual rainfall has been observed from 1977 to 2016. 10-years moving average of annual rainfall anomaly remained positive in most of the years. A great variation in maximum temperature anomaly was observed during the entire study period for all districts. Considering the climatic variations in the study area, there is need to analyze vulnerability of Punjab Province of Pakistan.
