Thermodynamic model of melt pond and its application during summer of 2010 in the central Arctic Ocean
-
摘要: 本文应用2010年夏季中国北极科学考察期间(CHINARE-2010)获得的观测数据建立了一个一维融池热力学模式。本文研究表明在太阳辐射能的作用下整个融池在垂直方向存在对流混合,从而导致整个融池水的温度和盐度比较均匀。大约有85%的太阳入射辐射穿过融池表面进入融池。其中进入融池的太阳辐射能一部分以感热和潜热的形式释放到大气中,但是这部分能量和进入融池的太阳辐射能相比相对较小(大约占15%)。超过59%的入射能量被融池水吸收,从而导致了融池水的温度发生改变。模拟结果表明融池水的温度主要在0.0-0.3℃之间,并且呈现日周期变化特征。模拟结果还显示融池下面的海冰融化速率是海冰底层融化速率的2-3倍。同时,当融池深度小于0.4米时,海冰融化速率变化比较快;当融池深度大于0.4米时,海冰融化速率变化比较慢(大约每天融化1cm)。Abstract: A one-dimensional thermodynamic model of melt pond is established in this paper. The observation data measured in the summer of 2010 by the Chinese National Arctic Research Expedition (CHINARE-2010) are used to partially parameterize equations and to validate results of the model. About 85% of the incident solar radiation passed through the melt pond surface, and some of it was released in the form of sensible and latent heat. However, the released energy was very little (about 15%), compared to the incident solar radiation. More than 58.6% of the incident energy was absorbed by melt pond water, which caused pond-covered ice melting and variation of pond water temperature. The simulated temperature of melt pond had a diurnal variation and its value ranged between 0.0℃ and 0.3℃. The melting rate of upper pond-covered ice is estimated to be around two times faster than snow-covered ice. At same time, the change of melting rate was relatively quick for pond depth less than 0.4 m, while the melting rate kept relatively constant (about 1.0 cm/d) for pond depth greater than 0.4 m.
