Analysis of extreme weather events over Kolhapur district of Western Maharashtra using RClimDex model

The study titled “Analysis of extreme weather events of Western Maharashtra region using RClimDex model” was conducted at the Department of Agricultural Meteorology, College of Agriculture, Pune, from 2021 to 2023. It analyzed 27 core indices derived from daily temperature and precipitation data collected from Kolhapur district over a 40-year period (1982-2022). The investigation revealed notable trends in extreme weather events within the region. Of the 19 temperature-based indices, five exhibited a decreasing trend, while twelve showed an increasing trend. Two indices, namely the number of frost days (FD0) and the number of ice days (ID0), were found to be non-significant. Specifically, indices such as the number of cold days (FD15), number of cool nights (TN10p), cold spell duration indicator (CSDI), and diurnal temperature range (DTR) demonstrated a significant decreasing trend. On the other hand, the number of tropical nights (TR20) and the number of warm nights (TN90p) indicated an increasing trend over the studied period. This comprehensive analysis of extreme weather events in Kolhapur district provides valuable information into the agro-climatic resources of the region. Such understanding is essential for optimizing agricultural output while ensuring the sustainable utilization of resources.
