ENSO occurs in tropical waters (Southern Equatorial Pacific) El Nino means ?The Child? because it usually happens around Christmas so its connected to the baby Jesus Solar Intensity and Latitude At low latitudes (near the equator) the sun?s rays are nearly vertical At high latitudes (near the poles) the sun?s rays are much less intense because the sun remains close to the horizon Tropical latitudes are the warmest Air rises there This causes convection cells (Hadley Cells) that constantly move air throughout the atmosphere Normal conditions in Southern Pacific These surface winds move warmer surface water to the west
