3. Causes:
El Nino is caused when trade winds allow warm water from the Pacific to flow east.
This builds up warm surface water that will soon cause the El Nino.
La Nina is caused when the temperatures drop in the pacific, also being blown east.
This builds up at the coasts and will cause a La Nina.
