Air-Sea Interaction: Laws and Mechanisms provides a comprehensive account of how the atmosphere and the ocean interact to control the global climate, what physical laws govern this interaction, and its prominent mechanisms. In recent years air-sea interaction has emerged as a subject in its own right, encompassing small-scale and large-scale processes in both air and sea. By developing its subject from basic physical (thermodynamic) principles, the book is broadly accessible to a wide audience. It is mainly directed towards graduate students and research scientists in meteorology, oceanography, and environmental engineering. The book will be of value on entry level courses in meteorology and oceanography, and also to the broader physics community interested in the treatment of transfer laws, and thermodynamics of the atmosphere and ocean.
