The role of daily surface forcing in setting the temperature and mixed layer structure of the Southern Ocean
Kamenkovich, I.V. 2005. The role of daily surface forcing in setting the temperature and mixed layer structure of the Southern Ocean. Journal of Geophysical Research 101, C07006, doi:10.1029/2004JC002610.
The role of high-frequency surface forcing in setting the temperature and mixed-layer structure in the Southern Ocean is investigated in an ocean general circulation model. The analysis suggests that daily fluctuations in the momentum flux, and the enhanced vertical mixing they produce, have the biggest effect on the time-mean temperature and mixed layer structure. In particular, summer-time surface temperatures are cooler, subsurface temperatures are warmer, and the mixed layer is thicker in the experiment with daily forcing than in the one without. The winter-time mixed layer in the Pacific sector is, however, thinner in the presence of daily forcing due to the enhanced density contrast between the mixed layer and the ocean below.
