“…Several studies have been conducted to understand the variations in precipitation dynamics across different regions of the world due to climate change (Thompson 1973;McQuate & Hayden 1984;Vilar & Burgueño 1995;Partal & Kahya 2006;Zin et al 2010;Cinco et al 2014;Tsidu 2017;Akinsanola & Zhou 2019). Many researchers have studied the spatio-temporal dynamics of precipitation at the state or country level in the context of climate change in India (Joshi & Rajeevan 2006;Guhathakurta & Rajeevan 2008;Chowdhury & Beecham 2009;Pal & Al-Tabbaa 2010;Subash et al 2011;Jena et al 2014;Pingale et al 2014;Taxak et al 2014;Gajbhiye et al 2016;Dwivedi et al 2019;Viswambharan 2019). Climate variability and climate change have altered the precipitation dynamics across the globe (Gergis & Henley 2017;Deng et al 2019;Singh et al 2019).…”

In this study, we investigated the spatio-temporal distribution and performance of seasonal precipitation in all districts of Haryana, India. We analysed the gridded precipitation dataset of the India Meteorological Department (IMD) for a period of 120 years (1901–2020) using different statistical methods. We found that Haryana received a mean precipitation of 37.0, 37.7, 468.3, and 24.8 mm during the winter, pre-monsoon, monsoon, and post-monsoon seasons, respectively. During each season, the eastern districts of Haryana received more precipitation than its western counterparts. Sen's slope results obtained after trend-free pre-whitening (TFPW) showed a statistically significant increasing trend of 0.12 mm (p-value; 0.04) during the pre-monsoon period, whereas decreasing but non-significant trends were observed during the winter, monsoon and post-monsoon seasons at the rate of −0.04 mm (p-value; 0.49), −0.26 mm (p-value; 0.52), −0.05 mm (p-value; 0.33) per year, respectively, for the entire Haryana state. The winter precipitation is expected to increase under the Representative Concentration Pathway 4.5 (RCP4.5) scenario, whereas pre-monsoon precipitation is expected to decrease under the RCP8.5 scenario by the end of the 21st century. The monsoon precipitation is expected to decrease under all RCP scenarios, whereas post-monsoon precipitation is expected to gradually increase under the RCP8.5 scenario by the end of the 21st century.
