Abstract
The present study attempts to investigate climatic trends in Southern Haryana between the periods of 1980-2017. Temperature and rainfall variations for winter, summer, monsoon and post-monsoon seasons were calculated using the Mann-Kendall test and Sen’s slope estimator. Results indicated that the temperature shows an increasing trend for winter (0.5657), monsoon (0.1529), and post-monsoon (0.0034). The results for rainfall shows negative Kendall's tau values for winter (?0.0953), monsoon (?0.0100) season, which denotes a decrease in rainfall over the years in the already dried region. The annual potential evapotranspiration (PET) trends were also shown using linear regression line indicated an upward trend over the years, which has increased 2.38 mm since in the last 37 years, increasing pressure on aquifers. In nutshell, we can say that temperatures are warming up and the rainfall has been shrinking exacerbating the situation for society and the environment.
