Request a sales quoteThermodynamics of Clouds is a coherent and rational account of the thermodynamics of clouds that requires only a little knowledge of general thermodynamics; which takes up each idea from the beginning and allows the reader to appreciate the degree of rigor or of approximation at each stage; and which discusses each hypothesis and develops each theory with a clear statement of the basic physical concepts. It places at the disposal of meteorologists a working tool which will allow them to master the problems encountered in this branch of meteorology. The book contains 13 chapters that can be organized into three general parts. The first part establishes the general formulas of the thermodynamics of surfaces. In the second part the general formulas that were established in the preceding chapters are applied to some meteorological problems. The third and final part of the book deals with the theory of condensation and crystallization germs.
