山区月平均气温的短序列订正方法研究

山区气象台站稀少,气象哨资料的时间序列较短,一般通过延长气象哨的时间序列来研究山区气候状况.本文以仙居县气象站为基本站,收集9个气象哨的气温资料,采用一元回归订正法和差值订正法对浙江省仙居县内9个气象哨的月平均气温进行订正,并从统计学和订正误差的角度分别对它们进行了比较分析.结果表明:采用一元回归订正法和差值订正法来订正误差无显著性差异,两者均可以用于山区月平均气温的短序列订正.

Research on adjusting methods of monthly average temperature series in mountainous area

Because of the sparse distribution of meteorological stations, the duration of single time series of meteorological data acquisition in the meteorological temporal stations is usually relatively short. So these time series in meteorological temporal stations is sometimes prolonged to meet the needs for studying the climate status in the mountainous areas. In this paper, the data of air temperature were collected from 9 meteorological temporal stations and one basic meteorological station in Xianju County, Zhejiang Province, the one-variate regression method and the difference value method were used to adjust the monthly average air temperature, and then the fitting errors produced by the two methods were calculated using statistical methods. The results indicated that the fitting errors produced were not significantly different between the two methods and can be applied to time series adjustment of monthly average temperature in mountainous areas.
