Abstract EN
Evapotranspiration is one of the most important hydrological variables in the context of water resources management.
An attempt was made to understand and predict the dynamics of reference evapotranspiration from a nonlinear dynamical perspective in this study.
The reference evapotranspiration data was calculated using the FAO Penman-Monteith equation with the observed daily meteorological data for the period 1966–2005 at four meteorological stations (i.e., Baotou, Zhangbei, Kaifeng, and Shaoguan) representing a wide range of climatic conditions of China.
The correlation dimension method was employed to investigate the chaotic behavior of the reference evapotranspiration series.
The existence of chaos in the reference evapotranspiration series at the four different locations was proved by the finite and low correlation dimension.
A local approximation approach was employed to forecast the daily reference evapotranspiration series.
Low root mean square error (RSME) and mean absolute error (MAE) (for all locations lower than 0.31 and 0.24, resp.), high correlation coefficient (CC), and modified coefficient of efficiency (for all locations larger than 0.97 and 0.8, resp.) indicate that the predicted reference evapotranspiration agrees well with the observed one.
The encouraging results indicate the suitableness of chaotic approach for understanding and predicting the dynamics of the reference evapotranspiration.
