Role of Mixing in the Dynamics of Upwelling Systems

  • J. D. Thompson


Observational data and theoretical models of coastal and equatorial upwelling have improved dramatically in recent years. Nevertheless, parameterization of turbulent mixing processes in upwelling regimes remains a serious, unsolved problem. In this contribution the role of mixing in the dynamics of upwelling systems is examined. An historical perspective is provided via a review of early pararneterizations of horizontal and vertical mixing in upwelling models, beginning with Ekman (1905). Recent ananlytical and numerical models of upwelling systems are examined in view of their inadequate mixing recipes. Some attempts to quantify the role of mixing in upwelling regimes by observational studies are described.
