Abstract | To promote the awareness of Priestley-Taylor (PT) model and extend the knowledge of hydrological model under snow, performance of PT model was illustrated by comparing with eddy covariance (EC) measurements over a temperate meadow. The results showed that the mean half-hourly averages and directly calculated daily value of PT parameter alpha is 0.47 +/- 0.27 and 0.51 +/- 0.32, respectively. Vapour pressure deficit V-PD is the mainly factor influences alpha in the snow-covered period, while soil moisture in the snow-free period. PT method underestimated evaporation in the whole study period and showed remarkable difference in different phases. It performed best in the snow-melting phase, better in the presnow phase, worse in the fresh snow phase and worst in the snow-melted phase. These studies indicated that PT model could be used to estimate evaporation over temperate meadow in dormant season, but utility of a variable PT parameter alpha during different phases should be considered. |
