五台山站气温、降水量资料均一性处理及变化趋势分析

Homogeneity Analysis of Historical Meteorological Data and Climate Change Tendency atWutaishan

本文利用1957—2013年五台山气象观测站的地面逐月气温和降水量资料，采用滑动T检验、回归订正法、线性倾向估计、滑动平均法等方法，分析了五台山站迁站前后气候资料均一性，并分析了其气温、降水量变化特征。结果表明：（1）1月、5—10月降水量序列在五台山站迁站前后无显著差异，其余各气象要素序列在五台山站迁站前后存在显著差异。（2）五台山年平均气温与四季气温呈上升趋势，平均每10年上升0-32℃（年）、O．36cC（春）、0．18℃（夏）、0.3代（秋）和0．50℃（冬）；年降水量与四季降水量呈现下降趋势，平均每10年下降-36．8mm（年）、-7．9mm（春）、-37．3mm（夏）、-11．4mm（秋）和-3．8mm（冬）。

The paper aims tostudy thehomogeneity of historical meteorological data and climate change tendency atWutaishan. According to the temperature and precipitation data of WutaishanStation from 1957 to 2013, homogeneity of historical meteorological data and climate change tendency at Wutaishan were analyzed by using the running T test, one - variate regression method, linear trend analysis, smoothing averages method. The results showed that：this station relocation caused significant difference on the other meteorological data, but not on the precipitation of temperature was 0.32℃/10 a , 0.36℃/10 a , 0.18℃/10 a , 0.31℃/10 a , 0.50℃/10 a . The average precipitation and seasonal precipitation were going down,and the rate of precipitation was -36.8mm/10 a,-7.9 mm/10 a, -37.3mm / 10 a , -11.4mm/10a and -3.8 mm/10 a.
