| Description | To explore the spatial and temporal variations of the reference evapotranspiration $(ET_{ref}$) is helpful to understand the response of hydrological processes to climate changes. In this study, $ET_{ref}$ was calculated by the Penman-Monteith method (P-M method) using air temperature, wind speed, relative humidity and sunshine hours at 89 meteorological stations during 1961–2006 in the Yellow River Basin (YRB), China. The spatial distribution and temporal variations of $ET_{ref}$ were explored by means of the kriging method, the Mann-Kendall (M-K) method and the linear regression model, and the causes for the variations discussed. The contribution of main meteorological variables to the variations of $ET_{ref}$ was explored. From the results we found that: (1) the spatial distributions of $ET_{ref}$ display seasonal variation, with similar spatial patterns in spring, summer and autumn; (2) temporal trends for $ET_{ref}$ showed large variation in the upper, middle and lower regions of the basin, most of the significant trends (P = 0.05) were detected in the middle and lower regions, and, in particular, the upward and downward trends were mainly detected in the middle region and lower region of the basin, respectively; and (3) sensitivity analysis identified the most sensitive variable for $ET_{ref}$ as relative humidity, followed by air temperature, sunshine hours and wind speed at the basin scale.
