The Effect of Interior Motion on Seasonal Thermocline Evolution.

Abstract

The response of the seasonal thermocline formation and mixing to prescribed vertical interior motion is examined. For the annual and shorter period interior motion cases studied, the response was strongest for the annual period. For an oscillatory vertical motion having a 15 m amplitude at a 75 m depth, warm sea surface temperature anomalies of up to 2.16 C and cold anomalies of up to 2.04 C are found, depending on the phase difference between the interior motion and the annual heat cycle. The net phase-averaged effect on the mixed layer for annual period interior motion is a reduction in vertical mixing. Higher frequency motion produces a net enhancement of the mixing. (Author)
