Soap bubble subjected to temperature variation between its base and apex. The heat creates convection currents on the surface of the bubble. Turbulence appears and large vortices form randomly like cyclones in the Earth's atmosphere. Indeed, soap bubbles have similar curvature and thickness to the Earth's atmosphere. The rotation of the bubble on the brass disk makes it possible to study the intensity and trajectory of the vortex and thus to elucidate variations in cyclone intensity and model…

A researcher blows into a tube to create a soap bubble on a heated rotating brass disk. Heat creates a thermal convection effect on the surface of the bubble. These flow simulations approximate as closely as possible a simple model of atmospheric flow, as soap bubbles reproduce the curvature of the atmosphere. The vortices obtained are comparable to tropical cyclones. The rotation rates of the bubble vortices help determine their path and intensity. The relationship obtained can be used to…

Study of the rotation rate of a vortex created by heat convection at the surface of a half-bubble of soap. In a light box, the researchers film the vortices on the surface of the bubble. The bubble is also subjected to a rotation similar to that of the Earth. The vortex created is an ideal model for the study of natural vortices such as cyclones in the Earth's atmosphere. By studying the trajectory and the intensity of the vortices on the surface of the bubble, a team of French researchers has…
