英文摘要 | This study investigates the association between the sea-land interface moisture flux and reference evapotranspiration during 1971-2010 in Liaohe Delta, Northeast China, which moisture flux is derived from NCAR/NCEP reanalysis I data and reference evapotranspiration is calculated by Penman-Monteith equation. The result shows that the sea-land interface moisture flux presents a seasonal variation with the highest value in summer and the lowest value in winter. The sea-land interface moisture flux and reference evapotranspiration show significantly positive correlation in spring and autumn and significantly negative correlation in summer. Consistent with the past field experiments, the sea-land moisture flux suppresses reference evapotranspiration in summer. The positive correlation reveals that the sea-land moisture flux, especially in surface sublayer, facilitates reference evapotranspiration in spring and autumn. Regressions analysis demonstrate that reference evapotranspiration increases when moisture flux of surface-to-850-hPa sublayer increases until reaches the threshold (67-75 kg/ms), and the opposite trend appears when moisture flux exceeds the threshold.
