The El Niño climate phenomenon is an event that occurs in the tropical Pacific Ocean.
It is characterised by abnormal warming of the ocean surface waters in that region. This warming can have important consequences for the global climate.
During an El Niño event, water temperatures in the tropical Pacific region become warmer than normal.
This can alter wind patterns and ocean currents, which in turn has effects on global climate.
The consequences of El Niño can vary depending on geographical location.
In some regions, such as South America, it can lead to heavy rainfall and more frequent storms. In other parts of the world, such as Southeast Asia, it can lead to droughts and adverse weather conditions.
It is important to note that El Niño is only one part of a broader phenomenon called El Niño-Southern Oscillation (ENSO). ENSO refers to the interactions between the El Niño phenomenon and another phenomenon called La Niña, which is basically the opposite of El Niño and is characterised by the cooling of surface waters in the tropical Pacific.
