| 摘 要： | Downburst is a very dangerous weather phenomenon for aeroplane taking off or landing. Inorder to understand the initial formation and evolution of downburst and to study the effects of at-mospheric environment condition and the microstructure of cloud-precipitation particles on thedownburst development processes, we have designed and carried out a modeling scheme by makinguse of our own non-hydrostatic compressible mesoscale-γ model including necessary cloud-precipi-tation processes. The initial conditions of temperature, humidity and wind are from an observationcase in which the downburst occurred. The results of computations demonstrate the evolution ofdownburst and show the variation of various environmental and microphysical parameters. Some ofthe mechanisms about the downburst occurrence have been obtained. Computation results mayhelp airport forecasters to determine the occurrence of downburst better.
