El Nino is a short time change in the climate in the pacific ocean. You can see the effects in both the air and water. The ocean will heat up a few degrees. The air therefore heats up to because the heat comes of the water and heats up the air. The heavy storms move to the east. These are small effects that can make a huge difference on the world’s climate. El Nino causes unusual warming of the surface waters of the oceans in the tropical pacific. One part is called the Southern Oscillation. The Southern Oscillation is the up and down pattern like a see-saw. Scientists do not understand the whole concept of how the El Nino works and forms.

The wind blows strongly from the east to the west. This piles up the water in the west. In a El Nino winds in it get weaker as it pushes the water around. Some of the warm water that is piled up in the west slides back to the east. Not much cold water get pulled up from under the warm water.

This usually happens around Christmas time in South America so they called it El Nino. This means the infant or the Christ child because it happens around Christmas.
A strong El Nino often is associated with wet winters all over the southeastern U.S. and drought in the Indonesia and Australia.
