Water Balance in Land-Atmospheric System over the Yalu Tsangpo River Basin

ZHANG Shun-li, TAO Shi-yan (Institute of Atmospheric Physics, Chinese Academy of Sciences, Beijing 100029, China)  
The characteristics of water balance over Yalu Tsangpo River basin in Tibet are researched by using NCEP/NCAR twice daily (0000 and 1200UTC) reanalysis data, monthly runoff and precipitation for the period of 1980-1989, and the evaporation, soil and surface water storage are also estimated. The main results are as follows: (1) the Yalu Tsangpo River basin acts as a moisture sink from May through October , where precipitation exceeds evaporation, and as a moisture source during November-April, where evaporation exceeds precipitation; (2) in Yalu Tsangpo River basin, precipitation mainly occurs during summer, and runoff, whose peak value lags that of precipitation one month, cheifly supplied by precipitation; (3) the soil and subsurface water storage decreases from January to June, but increases after July and reaches its maximum in October;and (4) over Yalu Tsangpo River basin there are raising trends in precipitation, evaporation, and runoff in late 1980s, which are related to ENSO events.
