Impact of Temperature Change on Reference Evapotranspiration in Dhaka City
In Dhaka city, the ambient temperature is changing as a consequence of changing climate and urbanization. The alteration in temperature is one of the most significant influencing factors that affect Reference Evapotranspiration (ETo). The study is comprehensively designed to examine the pattern of change in ETo over the period from 1953 to 2018. To fulfill the purpose of the study, temperature data of Dhaka throughout this period have been used. The trend of ETo has been analyzed for four different seasons: Pre-monsoon (March-May), Monsoon (June September), Post-monsoon (October- November), and winter (December- February). To evaluate the statistical significance of these patterns, a Mann-Kendall rank statistical significance test has been used. The result shows different trends for different seasons. There has been downward trending during the pre-monsoon and winter seasons, where the upward trending has been found during Monsoon and Post monsoon periods. All these trends are statistically significant at the 95% significance level.
