E1 Nino is the name given to the mysterious and often unpredictable change in the climate of the world. This strange   47   happens every five to eight years. It starts in the Pacific Ocean and is thought to be caused by a failure in the trade winds (信風(fēng)), which affects the ocean currents driven by these winds. As the trade winds lessen in   48  , the ocean temperatures rise, causing the Peru current flowing in from the east to warm up by as much as 5℃.

E1 Nino usually lasts for about 18 months. The 1982-83 E1 Nino brought the most  52  weather in modern history.

Scientists  54  this to be the longest E1 Nino for 2,000 years.

Nowadays, weather experts are able to forecast when an E1 Nino will  55 , but they are still not  56  sure what leads to it or what affects how strong it will be.
