This weather phenomenon features a sudden and very intense down flow that can cause even the most sophisticated aricraft to quickly lose altitude: Proper air1ine transport pilot training in flight simulators is an effective way of achieving greater safety to aircraft against microbursts. Both steady and unsteady multiple-vortex ring models are developed to simulate microbursts. The models use an impulsive free jet
