Back to basics: El Nino and Its Impact on Climate

El Nino is a climatic phenomenon characterized by the warming of surface waters in the central and eastern Pacific Ocean, which disrupts normal weather patterns globally. It often leads to reduced rainfall and drought conditions in parts of India, affecting agriculture and water availability. Understanding El Nino helps explain seasonal climate variability and its socio-economic impacts.
