Hurricanes as Heat Engines: Two Undergraduate Problems
Pyykko, Pekka
Journal of Chemical Education, v84 n3 p447-448 Mar 2007
Hurricanes can be regarded as Carnot heat engines. One reason that they can be so violent is that thermodynamically, they demonstrate large efficiency, [epsilon] = (T[subscript h] - T[subscript c]) / T[subscript h], which is of the order of 0.3. Evaporation of water vapor from the ocean and its subsequent condensation is the main heat transfer mechanism. The arguments presented here are simple enough to use as an illustration in a second-year chemical thermodynamics course.
