英文摘要: Management and scheduling of irrigation water requires consideration of evapotranspiration, one of the most important hydrological variables. This study investigates the variations in the daily potential evapotranspiration (ET0), and its aerodynamic (ETa) and radiometric (ETr) components in three areas (western, central and eastern) of the Inner Mongolia Autonomous Region (IMAR) during the growing season (April-September, 2007). In this study, a data-driven approach was followed, and the wavelet transformation analysis method was used to investigate the evapotranspiration characteristics of a relatively large geographic region. The results show that there are close correlations in the variations of ET0 with those of ETa and ETr. For the western area of the IMAR, the timing of the largest ETa is 1 month earlier and its wave period is 10 days shorter than those of ET0 and ETr. For the central area, the wave period of ETa is 20 days shorter, and the timing of the largest ETa is approximately 1 month earlier than those of ET0 and ETr. For the eastern area, there are two large fluctuations in ETa, and they occur 1 month earlier than those of ET0. © IWA Publishing 2017. Citation statistics:
