Soap bubbles for predicting cyclone intensity ?

Could soap bubbles be used to predict the strength of hurricanes and typhoons? However unexpected it may sound, this question prompted physicists at the Laboratoire Ondes et Matière d'Aquitaine (CNRS/université de Bordeaux) to perform a highly novel experiment: they used soap bubbles to model atmospheric flow. A detailed study of the rotation rates of the bubble vortices enabled the scientists to obtain a relationship that accurately describes the evolution of their intensity, and propose a simple model to predict that of tropical cyclones. The work, carried out in collaboration with researchers from the Institut de Mathématiques de Bordeaux (CNRS/université de Bordeaux/Institut Polytechnique de Bordeaux) and a team from Université de la Réunion, has just been published in the journal Nature Scientific Reports.
