辽东半岛本世纪气温变化的初步研究

A PRELIMINARY STUDY ON TEMPERATURE CHANGE SINCE 1905 OVER LIAODONG PENINSULA, NORTHEASTERN CHINA

中文摘要:

      近年来,关于中国地面气温变化的研究已经做了不少工作。由于国内绝大部分测站气象记录时间较短,温度变化的分析主要是集中在建国以后的近40多年内。为了更好地揭示和了解气候变化规律,需要建立全国或区域性的较长气温资料序列。我们根据5个测站1905年以来的记录和另外6个站建国以后的观测资料,计算了本世纪辽东半岛空间平均的冬、夏季和年温度距平值。这项工作表明,辽东半岛作为一个整体的温度变化特点既具有同北半球或全球变化相似的一面,又表现出明显的特殊性。

英文摘要:

      A comparatively long series of temperature data over Liaodong Peninsula has been offered in the present paper. The fluctuation feature of annual temperature bears a strong resemblance to that of the hemispheric average temperature, but the long-term temperature trend of the area is a little difference from that of the hemispheric average. The Peninsula's winter has become much warmer since the beginning of the century, while its summer has surprisingly become cooler. As a result, the annual temperature change is not yet so noticeable as expected. The contribution of the cities' growth and the changing heat island effects to the increase of winter temperature has been discussed. Also discussed are the possible causes of the obvious winter warming and the unusual summer cooling in the studied area.
