The El Nif1o phenomenon, which affects global weather patterns, is primarily characterized by:

1. Cooling of surface waters in the North Atlantic Ocean
2. Abnormal warming of surface waters in the central and eastern Pacific Ocean
3. Sudden increase in atmospheric pressure over the Arctic
4. Changes in the salinity levels of the Indian Ocean

Correct answer: Abnormal warming of surface waters in the central and eastern Pacific Ocean

Solution

El Nif1o is the warm phase of the ENSO cycle and is marked by unusual warming of sea-surface temperatures in the central and eastern Pacific Ocean. This disrupts normal atmospheric circulation and affects weather worldwide.
