Transport at the Air Sea Interface Measurements, Models and Parametrizations

About this book

Predictions of our future climate vary greatly, with detailed forecasts still subject to debate. One key uncertainty is caused by the lack of our present knowledge of transport processes in the air-water interface, which poses the main transfer resistance between the oceans and atmosphere. Modelling and predictions of our global climate can only be improved by gaining a more complete understanding of the mechanisms involved in transporting energy and mass between the atmosphere and the sea. This volume gives an account of recent progress in the domains of experimental process studies as well as computer stimulation. It represents a first approach of merging insights gained in both fields and broadens our understanding of the processes involved in air-water gas and heat exchange.
