Reference evapotranspiration concentration and its relationship with precipitation concentration at southern and northern slopes of Tianshan Mountains, China

The investigation of concentration characteristics of reference evapotranspiration (ETref) is important for water resources management. The concentration index (CI), concentration degree (CD) and concentration period (CP) are used to investigate the concentration characteristics of ETref and the relationship between ETref concentration and precipitation concentration at sub-monthly timescale based on the daily climatic variables from 1966 to...
