Assessing impact of climate change on rainfall patterns of Karaikal region, Puducherry, India

Global climate change may have a significant effect on several environmental components in many different nations worldwide. Variations in the pattern of precipitation have an immediate impact on the management of water resources. To improve water resource management techniques, it is critical to investigate differences in the temporal and geographical rainfall patterns. The current study looks at rainfall patterns in the Karaikal region, Union Territory of Puducherry. Utilizing the mean monthly data from rain gauge location and analysed rainfall statistics over an extensive timespan of 29 years (1996–2024). For precision in temporal categorization, this data was meticulously divided into four seasonal classifications: summer, winter, southwest monsoon (SWM), and northeast monsoon (NEM).
