Half the world's population is affected by Asian monsoons(季风)，but monsoons are difficult to predict.American researchers have put together a 700－year record of the rainy seasons，which is expected to provide guidance for experts making weather predictions.

Every year，moist(潮湿的)air masses，known as monsoons，produce large amounts of rainfall in India，East Asia，Northern Australia and East Africa.All this wet air is pulled in by a high pressure area over the Indian Ocean and a low pressure area to the south.

According to Edward Cook，a weather expert at Columbia University in New York，the complex nature of the climate systems across Asia makes monsoons hard to predict.In addition，climate records for the area are too recent and not detailed enough to be of much use.Therefore，he and other researchers spent more than 15 years traveling across Asia，looking for trees old enough to provide long－term records.They measured the rings inside thousands of ancient trees in more than 300 places.

Rainfall has a direct link to the growth and Width of rings on some kinds of trees.The researchers put together a Monsoon Asia Drought Atlas(地图集)documenting monsoons over seven centuries，beginning in the 1 300s.

“If the monsoon fails or is a very weak one.the trees affected by monsoons at that location might have a very narrow ring，”said Professor Cook.“But if the monsoon is very strong，the trees affected by that monsoon might have a wide ring for that year.”With all the information，researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.

“There has been widespread starvation and loss of human life in the past during large droughts while a particularly heavy monsoon can cause serious flooding，”said Eugene Wahl，a scientist with America's National Oceanic and Atmospheric Administration.“So，the regional moisture models，dryness and wetness over such along period of time in great detail mean a kind of victory for climate science.”

1．What's the passage mainly about?

A．The effects of Asian monsoons.

B．The necessity of weather forecast.

C．The achievements of Edward Cook.

D．A breakthrough in monsoon predictions.

2．It is difficult for experts to predict Asian monsoons because ________．
