张掖E601型与小型蒸发观测资料对比

Comparative Analysis of E601and Small-sized Evaporator Data in Zhangye of Gansu Province

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。

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.
