Is this a correct description?
Nino is a natural phenomenon where the pacific trade winds blow eastward towards south america which will be introduced to cooler weather with high precipitation and cooler seas while Australia on the other side of the pacific will get hot and dry weather with a higher sea temperature, this warmer seawater can damage coral reefs due to coral being sensitive to changes in temperature.
The opposite of El Nino is La Nina which is when trade winds go in the opposite direction, the countries swap conditions.
These two phenomenons are phases to a large phenomenon call ENSO.
