I have carried out a short research project at Arizona State University on microbursts. These microbursts are intense and sudden downdraughts of cold and water-loaded air from thunderclouds, and pose a hazard to aviation. To investigate the flow characteristics, I carried out laboratory experiments simulating the microburst with a salt water plume impinging on the bottom of a tank filled with fresh water. Measurements were taken of the propagation of the burst along the surface and the velocities within the burst, and the results compared favourably with meteorological observations.

Unfortunately, the text available online here does not include any of the graphs and equations. If you would like to receive a hardcopy of the full report, please let me know.
