Examining Rainfall Trends in Guntur District, Andhra Pradesh, India, Amidst the Climate Change Challenge: A Comprehensive Analysis of Global Warming Impacts

Due to increased anthropogenic activities like industrialization, urbanization, increased population density and size, land cover/use change, burning of fossil fuels, waste heat emissions from automobiles and industries, buildings, excessive use of air conditioning, rising levels of aerosols, and construction activities like reservoirs, nature has seen a transformation in climatic conditions at an unprecedented rate in recent decades. The goal of the current study is to examine the spatial and temporal variability in the Indian state of Andhra Pradesh’s Guntur District (Buishand (Journal of Hydrology 58:11–27, 1982)). The Indian Meteorological Department (IMD) statistics for the years 1988–2017 were used to compile information on factors relating to the rainfall in 20 chosen revenue mandals of the district. On an annual and decadal basis, numerous studies were performed using monthly rainfall values. Tables were used to show the results of the temporal and spatial studies. However, analyses of seasonal rainfall showed that there was a reduction in rainfall during the hot weather (Mar–May) and northeast monsoon seasons (Oct–Dec), but there was a slight increase in rainfall during the southwest monsoon season (Jun–Sep) and in the cold weather season (Nov–Feb). The analysis of rainfall in different Mandals of the District showed that the annual mean rainfall of all the Mandals is slightly dropping.
