Testing of the Turbulent Mixing Scheme Based on Similarity Theory in the Baltic Sea Model
Abstract
Ocean turbulent mixing scheme based on similarity theory is considered. This scheme’s been modified for including in 3-D ocean circulation model. Experiments have been made with the Baltic Sea model in which above mentioned scheme and scheme based on kinetic turbulent energy equation were used. It’s shown that simulation of temperature and salinity vertical distribution were improved.
