The El Nino, also formally known as the El Nino Southern Oscillation (ENSO) phenomenon, is a weather pattern which usually happens once every 3 to 7 years. Its main characteristic is the warming of the waters of the eastern section of the Pacific Ocean. This results in floods and droughts in different parts of the world, which, in turn, causes extensive damage to lives and property.
In the northern part of the world, the areas most vulnerable to the effects of this phenomenon are Mexico and the United States of America. The north-eastern and north-western parts of the US will often have mild winters while cooler and wetter winters will be experienced by parts of the south-eastern US, Virginia, and a few places in northern Mexico.
