Damaging Volcanic Ash Stays Well Beyond Welcome

The video discusses the impact of volcanic ash on air traffic, highlighting how ash can damage aircraft engines. Researchers, supported by the National Science Foundation, are studying the aerodynamic properties of ash to understand how long different particles remain in the atmosphere. Experiments in a wind tunnel at the University of New Hampshire demonstrate how particle shape affects suspension time. The findings are used to develop computer models for better forecasting ash behavior, aiding in predicting when skies will be clear for safe air travel after eruptions.
