三峡水库支流库湾热收支——以朱衣河为例
Heat budget of tributary bay in Three Gorges Reservoir: a case study of Zhuyi River
摘要
Abstract
In order to better understand the heat budget of tributary bay in reservoir,spatial-temporal distribution of water temperature structure,water surface heat fluxes and heat transports by advection are analyzed in this paper,based on the measured water temperature,meteorological data,and shortwave radiation data which are downloaded from National Oceanic and Atmospheric Administration (NOAA).Results show that (1) water surface temperature of Zhuyi Bay ranges from 12.0 ℃ to 31.6 ℃,and bottom temperature ranges from 11.8 ℃ to 27.8 ℃.(2) Influenced by the interaction between the main stream and the tributary,there is temperature difference in water surface along the tributary bay,and the net heat flux at the confluence of the main stream and tributary ranges from-63.02 W/m2 to 128.81 W/m2,in the middle reaches of tributary it ranges from-62.01 W/m2 to 116.14 W/m2,and in the upstream of tributary bay it ranges from-59.31 W/m2 to 78.04 W/m2.(3) The heat transports by advection correlate with the fluctuation of water level.(4) The heat transports by advection is the main factor of the changes of water heat content in the tributary.关键词
