The dependence of the wind profile power-law exponent (p) on surface roughness and atmospheric stability is depicted assuming a height variation of p (Huang, 1979; Hanafusa et al., 1986) and using the formulation of Zilitinkevich (1989) for determinin...

Micro pulse lidar is a promising tool for retrieving the convective boundary layer height (CBLH), but its application has been hindered by sharp extinction of the signal in high humidity conditions, e.g., clouds. To remedy this, we developed an effective...

The bursting phenomenon consists in the switch of a laminar separation bubble from a short to a long configuration. In the former case, reduced effects on profile pressure distribution are typically observed with respect to the attached condition. On the...
