黄河内蒙古段蒸发皿蒸发量变化特征
Analysis of pan evaporation of Inner Mongolia in the Yellow River Basin
摘要
Abstract
The variation of 20 cm pan evaporation in Inner Mongolia in the Yellow River Basin was analyzed based on 20 cm pan evaporation data of 26 weather stations from 1959~2008 by using the method of climate tendency coeffi-cient and climatic trend rate . The results showed that the average annual and average seasonal pan evaporation declined . But the variation of annual evaporation sequences of 26 weather stations was not completely consistent with average pan e- vaporation of the whole region , it was in fluctuation , and in which spring and summer were the majors . The meteorologi-cal elements had different performance in pan evaporation of different regions , "pan evaporation paradox" was not abso-lutely correct.关键词
