Every four or ten years, something happens to the weather system. Everything changes, and scientists don’t understand why people call this ‘El Nino’. It usually happens at Christmas time and El Nino is the Spanish name for the baby Jesus. The El Nino that started in 1982 was different from the other recent ones. It caused huge changes in the ocean currents. It caused floods in some areas and droughts in others. There were terrible windstorms and huge ocean waves swept houses into the sea. It did billions of dollars worth of damage. Thousands of people lost their lives and thousands of others were left homeless. In 1983 the winds, ocean currents and pressure areas started to become normal again. Scientists throughout the world are using satellites and research boats to observe the atmosphere and the ocean. It is a very complicated problem, but if the scientists of the world work together, they should be able to find out the causes of El Nino. Then they will be able to predict what will happen and work to prevent a repeat of the death and destruction of 1982-1983 1.How often does El Nino happen?
