摘要/Abstract

摘要： 在一维涡扩散模型的基础上，发展了考虑冬天结冰和夏天蒸发等水体相变问题及对流混合过程的湖气水热传输模型.模型采用焓代替温度作为预报变量，这也更加方便处理水的相变过程.模型的计算结果与以色列Kinneret湖的观测资料进行对比，验证了模型的合理性，说明了加入对流混合过程是符合湖-气水热传输的实际物理机制的.

关键词: 大气环境, 湖泊环境, 湖-气水热传输, 陆面过程

Abstract: Based on a one-dimensional eddy diffusion model, heat and mass exchange between atmosphere and the water body is modeled, which includes the phase change of water in winter and summer and emphasizes the importance of the convective mixing process. The model uses enthalpy instead of temperature as the forecast variable, which is convenient for the treatment of phase change process. The model is verified by observed data of Lake Kinneret. It is shown that adding convective mixing process conforms to the physical mechanism of heat and mass exchange between atmosphere and the water body.

Key words: atmosphere-environment, lake-environment, land surface process, heat and mass exchange between atmosphere and lake
