摘要
分析山东省济宁市气象要素值随时间的变化,可为研究该地区气候变化特征提供科学参考。对比分析了济宁市1971～2000年(前30 a)与1981～2010年(后30 a)气象资料中气温、湿度和降水量等主要气象要素的变化情况。结果表明:济宁前30 a与后30 a的气候特征总体变化趋势一致。其中后30 a,气温上升较为明显,且春、冬两季增温明显;湿度变化不大;年降水量增多,但冬季降水减少明显;年日照时数减少,且存在夏秋两季减少、春季增多的季节分布特征。
The changes of temperature, humidity and precipitation from 1971 to 2000 （pre 30 years） and from 1981 to 2010 （post 30 years） in Jining were analyzed. The results showed that the change trend of pre 30 years and post 30 years was uniform. From 1981 to 2010, the temperature rose obviously, especially in spring and winter, the humidity changed little, the annual precipitation increased, while the precipitation decreased obviously in winter, the annual sunshine hours decreased, the sunshine hours in summer and autumn decreased, and that in spring increased.
