Introduction to El Nino
Before diving into the specifics of the 2015-2016 event, it is essential to understand what El Nino is. El Nino, which translates to “The Little Boy” in Spanish, refers to the warming of sea surface temperatures in the central and eastern tropical Pacific Ocean. This warming of ocean water temperatures can have significant effects on the climate, leading to alterations in precipitation and temperature patterns across the globe. El Nino events are a natural part of the El Nino-Southern Oscillation (ENSO) cycle, which also includes La Nina events, characterized by cooler-than-average sea surface temperatures in the same region.
Causes and Characteristics of El Nino
The causes of El Nino are complex and involve interactions between the ocean and atmosphere. Normally, trade winds blow from east to west along the equator, pushing warm water towards Asia. During an El Nino event, these trade winds weaken or even reverse, allowing the warm water to flow back towards the eastern Pacific, near the coast of South America. This shift in ocean currents and temperatures can lead to significant changes in rainfall patterns and atmospheric circulation.
The characteristics of El Nino events can vary, but common features include:
– Increased sea surface temperatures in the eastern Pacific.
