Abstract

Discussed in this work is a means of modelling the response of the upper layer of the ocean and lake to atmospheric forcing. This is investigated us- ing a recently developed one-dimensional, second-order, turbulence closure scheme. Explained in this study are some differences between modelling lakes and oceans as well as weaknesses and limitations in one-climensional modelling. The success of the model is judged over various time scales against several observational data sets including: data from ocean weather- ship station Papa, data from the LOTUS experiment, and lastly, data from Lake Ontario. Comparisons between simulated and observed sea-surface temperatures are presented. 1 Introduction The exposed upper portion of a large body of water, whether it be a lake or ocean, is constantly subjected to atmospheric forcing imposed at its surface.
