Scientists think that a weather pattern（形式）called El Nino（厄尔尼诺现象）caused the
drought（干旱）in Australia．El Nino causes different weather in different parts of the world．It
causes a lot of rain and floods in some places．It causes droughts in other places．Droughts can badly affect people and the land．El Nino lasts about a year．
In normal weather conditions, warm winds from South America blow from east to west across
the Pacific Ocean．The winds early storms to Australia．These storms bring rain to Australia．
During an El Nino weather pattern．the winds change direction．They blow from west to east
across the Pacific Ocean．The storms no longer move across Australia．So Australia gets very little rain during El Nino．
The drought began in January，1982．E1 Nino often occurs at this time of year．But that year，
E1Nino was stronger than usual．There Was very little rainfall（降雨量）in eastern Australia．There was also very little water in the rivers．The drought was at its worst in February，1983．At that time，the weather was very hot．The forests and fields were very dry．Cotton growers wouldn’t plant their cotton．Sheep farmers had no grass for their animals to eat．So many of them died．Because the forests were dry．forest fires started quickly．Some of the fires burned for a month．Many forests were destroyed．Over 2,000 people lost their houses in the fires and 75 people died．
The Australian drought of 1982-1983 affected thousands of people and animals．The drought
cost the country over$3,000，000，000．It was a reminder（提示）to Australians of how the weather
could change their lives．
