Oceanic Circulation Models: Combining Data and Dynamics [E-Book] / edited by David L. T. Anderson, Jürgen Willebrand
This book which is the outcome of a NATO-Advanced Study Institute on Mod elling the Ocean Circulation and Geochemical Tracer Transport is concerned with using models to infer the ocean circulation. Understanding our climate is one of the major problems of the late twentieth century. The possible cl...
