佳木斯市地温与气温的关系

Relationship between Ground Temperature and Air Temperature in Jiamusi City

运用气象统计学和气象学的原理和方法,利用佳木斯市1990～2009年气象观测资料,对该市地温和气温的年变化规律及相关关系进行了分析,并建立基于地温的四季最高气温及最低气温的预报模型。结果表明,基于0 cm地温和气温年变化趋势有相似之处,分别建立了以地温为基础的最高、最低气温预报模型。通过该模型的相关性检验而得到了它们之间有很好的一致性,方程通过显著性检验;最低预报方程可以分季节应用不同方程来指导预报,最高气温方程更适合冬季应用。

By using principle and methods of meteorological statistics and meteorology, and the observation data in Jiamusi City during 1990 - 2009, the annual variation law of ground temperature and air temperature as well as their correlationship were analyzed. The highest air tem perature and the lowest air temperature prediction model based on ground temperature were established. The results showed that the annual variation trend of ground temperature and air temperature has similar characteristics ： the lowest prediction equation could be guided with differ- ent euuations in different season,the highest temperature equation is more suitable for winter.
