Resumen de Einsteins Tea Leaves and Pressure Systems in the Atmosphere
Tea leaves gather in the center of the cup when the tea is stirred. In 1926 Einstein1explained the phenomenon in terms of a secondary, rimtocenter circulation caused by the fluid rubbing against the bottom of the cup. This explanation can be connected to air movement in atmospheric pressure systems to explore, for example, why lowpressure systems tend to be stormy and highpressure systems are fair weather. Here, following Einsteins lead, we revisit the tea leaf phenomenon, make the connection with atmospheric pressure systems, and describe an illustrative laboratory experiment.
