Abstract

This paper is concerned with modelling the oceanic mixed layer at a high- latitude location in the Labrador Sea. Several simulations were carried out spanning the period 1964-1971 and will be presented during the presenta- tion; however, this study will focus on one simulation covering the years 1969-1971. The key result advocated here is that the mixed-layer model cannot simulate salinity well and this can have important implications in climate modelling. 1 Introduction The mixed layer refers to the upper portion of the ocean that is in direct contact with the atmosphere. It is usually observed to be well mixed and is modelled as a continuously stratified fluid. The mixed layer plays an im- portant role in communicating and negotiating fluxes with the atmosphere. One-dimensional mixed-layer models offer a means of investigating the
