Abstract: Using the methods of micro meteorological observation, designed “Microclimate and
Evaporation Experiment” in the northwest arid area of China, three pans evaporation were observed in
the same environment, compared the characteristics of the three pans evaporation, and analyzed the
relationship between four principal meteorological factors(wind speed, air temperature, air humidity
and solar radiation) and pans evaporation in process the hourly variation. In addition, combined the
observation data of meteorological factors, according to methods of numerical analysis and MRER,
assuming that other meteorological factors remained constant, got the contribution and sensitivity of
one of four meteorological factors to three pans evaporation. The results showed that the sensitivity of
wind speed, air temperature, air humidity and solar radiation on 20cm pan evaporation were
,,- and , on CLASS A pan evaporation were ,,- and
,on
