【摘要】：為更好認(rèn)識水庫庫灣熱收支過程,本文利用實(shí)測水溫、氣象和美國國家海洋和大氣管理局(National Oceanic and Atmospheric Administration,NOAA)短波輻射等資料,分析了朱衣河庫灣水溫結(jié)構(gòu)的時(shí)空變化、水面熱通量和平流輸運(yùn)熱量的年內(nèi)變化,結(jié)果表明:(1)朱衣河庫灣年內(nèi)表層水溫為12.0~31.6℃,底層為11.8~27.8℃;(2)受干-支流相互作用影響,支流表層水溫沿程存在水溫差,導(dǎo)致干-支流交匯處凈熱通量變化為-63.02~128.81 W/m~2,支流中部為-62.01~116.14 W/m~2,上游回水末端為-59.31~78.40 W/m~2;(3)支流水體的平流輸運(yùn)熱量與水位變化具有很好相關(guān)性;(4)影響支流水體熱含量變化的主導(dǎo)因素是平流輸運(yùn)熱量。
[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，
