Scientists think that a weather pattern（形式）called El Nino（厄爾尼諾現(xiàn)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．
