Abstract

Based on the FAO-56 Penman-Monteith equation, the changes of reference crop evapotranspiration (ET0) were studied by analyzing the sensitivity coefficients of ET0 to air temperature, wind speed, relative humidity and shortwave radiation together with their relative changes in growing season in Northwest China using a 49-year dataset. The results show that the changes of ET0 are primarily attributed to wind and air temperature due to their significant trends. Shortwave radiation and relative humidity have negligible effects on ET0 for their insignificant trends. The positive contribution of temperature and the negative contribution of wind and solar radiation are observed in most regions, but the contribution of relative humidity is positive in eastern part and negative in western part. The consistence between the actual ET0 changes and the estimated ET0 changes calculated by the contribution of four meteorological variables indicates that the method based on sensitivity coefficients interpreted together with actual changes in variables to quantify the impact of each variable on the ET0 trend is reasonable.

Key words： reference crop evapotranspiration; Penman-Monteith equation; Northwest China
