Explaining El Nino and La Nino

Warm water is at the top of the ocean and cold water is at the below it. Usually wind  blows from Peru to Indonesia and pushes  the warm water away. Therefore no rain falls near Peru because all the warm water has been pushed west. When El Nino happens no wind pushes the warm water west. This means it rains in Peru when it is not supposed to.

When the wind blows harder than usual from Peru to Indonesia to pushes the warm water further west than normal from Peru to Indonesia. Causing intense rain in South West Asia.
