摘要:

通过对张掖站1985 ~ 2001 年5 ~ 9 月E601( 金属制) 与玻璃钢制蒸发资料及E601 型与小型蒸发观测资料进行相关分析和对比分析,得到如下结果: ( 1) 金属制与玻璃钢制E601 型蒸发资料可做为同一资料序列使用; ( 2) E601 型与小型蒸发资料相关性达88% 以上,由比值折算系数求得的气候估计值与实际观测值更接近,优于使用一元线性回归系数折算的气候估计值资料序列,可以根据需要实现E601 型与小型蒸发资料序列的相互补充订正,在气象业务与服务中应用。

关键词: 蒸发量, 资料分析, 气候估计值

Abstract:

 Based on correlation analysis and comparative analysis of two kinds of evaporation data from E601 and small - sized evaporator in May to September during 1985 - 2001at Zhangye station,some results are obtained as follows: ( 1) E601 and E601B evaporation data can be used as the same sequence data; ( 2) The correlation of E601 and small - sized evaporator data is up to 88% ,and the climate estimate value caculated by the ratio conversion coefficient is close to actual observations and better than climate estimate value caculated by using a linear regression coefficient. The E601 and small - sized evaporator data can be corrected each other.

Key words:  evaporation data, E601 evaporator, small - sized evaporator, climate estimation
