In laboratory experiments designed to model atmospheric circulations, heat sources and sinks have, in the past, been solely accomplished by simple heating andor cooling at boundaries of rotating fluids. An entirely new technique, taking the form of a chemical analog to the atmospheric process of latent heat release upon condensation of water vapor, is employed in a liquid model of the hurricane circulation. Outstanding among the similarities is the development of a rotating, ring-shaped, convective wall structure with descent interior to the wall. Criteria are established for the formation and maintenance of the vortex. An experiment with typical well-developed ring convection is chosen for comparison with the prototype hurricane. The laboratory model has adequate similarity with the prototype it is, however, not claimed that the model is a miniature hurricane. Author
