A theoretical model is developed for making computerized forecasts of mixed layer depth. An empirical equation relating significant wave height to layer depth is used to account for mechanical mixing. Heat exchange parameters are introduced into the model to produce convective mixing. The u and v components of surface current are used to investigate the effect of convergence and divergence. The layer depths forecast by the model are compared to actual layer depths and to the Fleet Numerical Weather Central layer depth analysis.http://archive.org/details/investigationofv00elliLieutenant, United States NavyApproved for public release; distribution is unlimited
