Influence of Teleconnection Indices on Extreme Precipitation and Vegetation Index in Chalakudy River Basin

This study investigates the influence of global teleconnection indices on extreme precipitation events and vegetation dynamics in the Chalakudy River Basin, Kerala, India. The basin, characterized by high rainfall variability, is highly susceptible to climate-induced hydrological extremes. ENSO events, particularly El Niño and La Niña, significantly influence rainfall and vegetation. This research integrates statistical, spatial, and wavelet analysis using R Studio and ArcGIS to explore these relationships. The findings contribute to climate-resilient planning, flood preparedness, and sustainable water resource management strategies under changing climate conditions.
