1) entrainment
[in'treinmənt]
夹卷
1.
The bias is common to the current OGCMs,which has been ascribed to the model deficiencies in the parameterization of entrainment and vertical mixing process.
这表明在赤道东太平洋及南美沿岸,温跃层的变化通过夹卷过程及垂直扩散过程可以显著影响混合层的温度,OGCM对这些过程描述不足是导致SST年际变化模拟偏弱的一个重要原因,通过强调这些过程可以改善模拟效果。

2) entrainment rate
夹卷速度
1.
Based on the "first-order model" of convective boundary layer(CBL),an improved parameterization for the entrainment rate of CBL was proposed.
基于对流边界层“一阶模型”,并考虑机械湍流和夹卷过程对对流边界层发展的贡献,提出了对流边界层顶部夹卷速度参数化的改进方案。

应用 1979年 7月美国CIRCE试验边界层观测资料对两个夹卷速度参数化方案进行了对比验证 ,结果表明 :基于简单夹卷层结构模型的参数化方案we/w =A·Ri- 1 只适用于自由对流边界层 ,当对流边界层中存在较强机械湍流时 ,该方案变得不再适用 ;而基于“侵吞模型”的参数化方案we/w =B·θ /(Γzi)则不仅适用于自由对流边界层 ,对于含有较强机械湍流的对流边界层也能较好地符合 ,因而具有较强的适用性 。
