Within the visual identification of clouds, active mixing takes             place between the cloudy air and the drier air of its environment.              Recent observations of stratocumulus entrainment provide evidence               that dry air mostly enters from the cloud top instead of from the               lateral boundaries.  At present, the entrainment mechanism is not               fully understood.                                                                   The entrained volume, with the cooler and drier air from above,             dilutes the cloudy air, is negatively buoyant, and therefore descends           within the cloud.  Based on field observations and laboratory                   experiments, the entrained blob of air is envisioned to behave like a           spherical vortex, with strong updraft in the middle of the blob and             slower rising or descending air around the periphery.  Under this               grant, Profesor Telford will examine the dynamics of a turbulent                spherical vortex and implement it in a cloud model.  Since the                  entrainment processes may play a significant role in explaining the             finite life time of cumulus clouds and in predicting various cloud              drop size spectra observed around the world, Professor Telford's new            theory, if successfully tested, will be a major contribution to cloud           modelling.
