1. SPEI results showed a similar pattern, with the most negative trend observed in Kurnool;Chittoor Kadapa;Spatial Trends in Drought Indices: SPI and SPEI indicated consistent agricultural droughts
2. Kurnool received the most rainfall, followed by Chittoor, Kadapa, and Anantapur. Interestingly, recent years have seen a rapid rise in temperatures across the region, with the highest temperatures observed in Kadapa;Anantapur Kurnool;Temporal Distribution: The highest rainfall occurred in September
3. Temperatures exhibited high positive trends in the first three decades, followed by a low positive trend afterward. Kurnool experienced the most significant positive rainfall trend;Decadal Trends;SPEI showed the most negative trends in Chittoor, followed by Anantapur, Kadapa, and Kurnool. Notably, the fifth decade was the only one with a positive increasing trend in all Rayalaseema districts
