摘要:

2010 年9 月下旬以来( 2010 年9 月21 日至2011 年2 月24 日,下同) 山东省出现严重的秋冬连旱天气,是自1951 年山东省有气象水文纪录以来无有效降水持续时间最长、覆盖范围最广的气象干旱,创下了新中国成立以来同期之最。对2010 年9 月至2011 年2 月的气候资料进行统计分析,结果表明: 大气环流形势异常和水汽条件不足导致了山东降水量异常偏少,温度偏高,土壤失墒快,从而造成了山东省严重的干旱灾害,不仅使农业生产受灾严重,还对工业生产和人畜饮水造成了极大的危害。此外,山东特殊的地理位置、气候特点以及其他一些人为因素等也是造成此次严重干旱灾害的原因之一。

Abstract:

There was serious drought event occurred from autumn 2010 to winter 2011 in Shandong Province,which covered widely andvlasted longest time and created a new meteorology and hydrology record with no effective rainfall since 1951. The climate data from September 2010 to February 2011 were analyzed,it shows that lack moisture condition and abnormal atmospheric circulation resulted in less precipitation and higher temperature,so soil moisture lost fast,which caused severe drought disaster in Shandong Province. It not only damaged the agricultural and industrial production,but also caused human as well as livestock drinking water lack. In addition, the special geographical position and topography,and climate characteristic and human impacts were one of reasons causing the drought disaster in Shandong Province.

Key words: Shandong Province, drought event from autumn to winter, causes, atmospheric circulation
