湍流交换系数 meaning in Chinese
turbulent exchange coefficient
Examples
- A transfer model is established , which can be used to study the interaction between the land surface physical processes of inhomogeneous region and the structure of atmosphere boundary - layer over urban and rural terrains . the model has simulated surface heat flux , surface temperature , temperature profiles , height of mixture layer and so on . and the differences between urban area , suburban area and rural area have been compared . this model mainly depends on the parameters below : surface albedo , surface roughness coefficient , moisture available coefficient of soil , thermal capacity and thermal diffusion coefficient of errain , cloudage . the result shows that this model can simulate the structure and eigenvalues of atmosphere boundary layer and their changes in a day . parameters used in this model aim at beijing city , and the time is at the beginning of september . to other cities , or other time , the parameters should be adjusted accordingly . in addition , being adjusted , the model can also be used for other homogeneous and inhomogeneous terrains
模式主要依赖于以下参数和物理量：地面反照率下垫面粗糙度土壤的可含水量下垫面的热容量和热扩散系数云量等参数。结果表明，本模式能合理地模拟不同地表热量平衡地表气温混合层高度湍流交换系数湍流动能位温廓线等，以及它们的日变化。该模式所取参数主要针对北京市，时间为九月初，对于其他城市，参数应作相应的调整。
