TREND analysis of changing temperature in Bangladesh due to global warming
Journal Title: Journal of Biodiversity and Environmental Sciences (JBES) - Year 2013, Vol 3, Issue 2
Abstract
Long term changes in near-surface air temperature over Bangladesh was studied using the available historical data of maximum and minimum daily temperature for the last 60 years (1949-2008) collected by the Bangladesh Meteorological Department (BMD). Analysis was done by using MAKESENS trend model. It has been observed that the temperature increased significantly at the rate of 0.00569 oC Yr-1 for AMXT, 0.014498 oC Yr-1 for AMNT and 0.010262 oC Yr-1 for AMT. It is evident that AMXT and AMT raised to maximum levels during November by 0.023 oC Yr-1 and 0.02597 oC Yr-1 respectively. However, AMNT increased to its maximum during February at 0.0308 oC Yr-1. It was also found that maximum increase in AMXT occurred at Shitakundu (0.058102oC Yr-1), in AMNT at Madaripur (0.042 oC Yr-1) and in AMT at Kutubdia (0.031113 oC Yr-1). Southern parts of the country showed higher increasing trends of daily AMXT than other parts. Northern and north-western parts had higher rate of increase in daily AMNT, whereas the daily AMT has increased more in the southern and south-western parts. During Rabi season AMNT increased by 0.023 oC Yr-1 and AMT by 0.013 oC Yr-1. In Kharif-1 AMNT increased by 0.012 oC Yr-1 and AMT by 0.006 oC Yr-1, whereas in Kharif-2 AMXT increased at 0.011oC Yr-1, AMNT at 0.005 oC Yr-1 and AMT at 0.008 oC Yr-1. Besides, the temperature of winter season (December to February) has been raised at much higher rate than summer season (June to August). This study also showed that temperature has been increased to much higher levels over the last 30 years (1979-2008) than the last 60 years (1949-2008).
