【摘要】：为更好认识水库库湾热收支过程,本文利用实测水温、气象和美国国家海洋和大气管理局(National Oceanic and Atmospheric Administration,NOAA)短波辐射等资料,分析了朱衣河库湾水温结构的时空变化、水面热通量和平流输运热量的年内变化,结果表明:(1)朱衣河库湾年内表层水温为12.0~31.6℃,底层为11.8~27.8℃;(2)受干-支流相互作用影响,支流表层水温沿程存在水温差,导致干-支流交汇处净热通量变化为-63.02~128.81 W/m~2,支流中部为-62.01~116.14 W/m~2,上游回水末端为-59.31~78.40 W/m~2;(3)支流水体的平流输运热量与水位变化具有很好相关性;(4)影响支流水体热含量变化的主导因素是平流输运热量。
[Abstract]:In order to better understand the heat budget process of reservoir bay, the temporal and spatial variation of water temperature structure, surface heat flux and advection heat transport in Zhuyi River Bay are analyzed by using measured water temperature, meteorology and (National Oceanic and Atmospheric Administration,NOAA short wave radiation of the National Oceanic and Atmospheric Administration of the United States. The results show that: (1) the surface water temperature of Zhuyi River Bay is 12.0 鈮，
