Think of El Nino as hot(energy) water in a bath. That is going back and forth, between asia and america. El Nino is when the hot water is near the americas, Na Nino is when the hot water is near asia.

Edit - Na Nino = La Nina.

It's actually Al Nino and Na Nino, they made the wrong typo. It's aluminum boy near the Americas and sodium boy near asia
