Written for researchers, students and engineers who are involved with the study, interpretation and prediction of gravity current flows in fluids, this textbook uses a mathematical framework to interpret experimental results and measurements.
An introduction to gravity currents and intrusions.
In atmospheric gravity currents, such as sea-breeze fronts or thunderstorm outflows, the density difference is typically caused by a temperature difference between a dense spreading cold front and relatively warm less dense ambient air [1, 2].
