We generate explicit height-dependent eddy viscosity coefficients in the Ekman layer from convex wind speed profiles. The solutions we obtain are parameterized in terms of the relative deflection angle between the wind directions at the top and bottom of the flow, as well as the geostrophic wind speed and a velocity scale we interpret as the transfer rate of horizontal momentum in the vertical direction. The solutions may be used to infer the thickness of the Ekman layer for a variety of deflection angles different from the deflection angle of the classic Ekman spiral.

根据年龄变化的风速分布在大气边界层中的可变涡流粘度

我们根据凸风速剖面在Ekman层中生成显式的与高度相关的涡流粘度系数。我们获得的解的参数化取决于流顶部和底部的风向之间的相对偏转角，以及地转风速和速度标度，我们将其解释为垂直方向上水平动量的传递速率。该解决方案可用于针对与经典埃克曼螺旋线的偏转角不同的各种偏转角推断埃克曼层的厚度。
