El Nino is a disturbance of the world’s normal climate pattern.During El Nino events,the westerly trade winds become slower and the warmer water in the western Pacific moves towards South America.This huge increase in ocean temperatures — as much as eight degrees centigrade — and the change in atmospheric conditions bring rain to the deserts of South America and the rainforests of south-east Asia,with drought conditions throughout eastern and southern Africa.There are many knock-on effects all over the world.
