摘要: A description is given of experiments and calculations performed to investigate the effect entrainment undersaturated air upon microphysical structure cap clouds at Great Dun Fell, Cumbria. Three case studies are presented: in I properties cloud were essentially adiabatic; II provided evidence for mixing intermediate between homogeneous extreme inhomogeneous types; III was extremely inhomogeneous. Consistent with this picture, time constant turbulent erosion entrained parcels significantly greater than III. Spectral changes observed agree well predictions from a diffusive model (Baker Latham 1982).
