Spatiotemporal Characteristics of Reference Crop Evapotranspiration in Inner Mongolia from 1959 to 2018
To comprehensively understand the impact of climate change on reference crop evapotranspiration (ET<sub>0</sub>) in Inner Mongolia,the daily ET<sub>0</sub> of 50 meteorological stations in Inner Mongolia in the past 60 years was calculated using the FAO Penman-Monteith formul...

| description | To comprehensively understand the impact of climate change on reference crop evapotranspiration (ET<sub>0</sub>) in Inner Mongolia,the daily ET<sub>0</sub> of 50 meteorological stations in Inner Mongolia in the past 60 years was calculated using the FAO Penman-Monteith formula,and further investigated spatiotemporal characteristics,interdecadal and cyclical changes of ET<sub>0</sub> in Inner Mongolia.The results showed that the distribution trend of ET<sub>0</sub> gradually decreased from west to east in Inner Mongolia,the multi-year average was 1 018 mm,while the climate tilt rate was 4.2 mm/10a,showing a significant upward trend.The sum of ET<sub>0</sub> in spring,summer and autumn,the growing periods of crops,accounted for about 95% of the total annual value,while the spatial distribution was similar to the annual value.The annual average ET<sub>0</sub> in various climate zones followed a descending order:ultra-arid climate zone,arid climate zone,semi-arid climate zone,dry and semi-humid climate zone,humid and semi-humid climate zone.The variation coefficients of the climate zones were low,showing weak variability,and abrupt changes occurred in different climate zones at the end of the 1990s.The ET<sub>0</sub> change cycles were mainly 59a,14a and 24a. |
