Ocean Mixed Layer Depth From Dissipation

Ocean Mixed Layer

The ocean mixed layer (OML), the ocean region adjacent to the air–sea interface, is typically tens of meters deep, and due to the fact that it is well mixed, the temperature and salinity (and therefore the density) are fairly uniform. The rapidly changing regions below these uniform regions of temperature, salinity, and density are called the thermocline, halocline, and pycnocline, respectively...

The effect of ocean mixed layer depth on climate in slab ocean aquaplanet experiments

The effect of ocean mixed layer depth on climate is explored in a suite of slab ocean aquaplanet simulations with different mixed layer depths ranging from a globally uniform value of 50–2.4 m. In addition to the expected increase in the amplitude of the seasonal cycle in temperature with decreasing ocean mixed layer depth, the simulated climates differ in several less intuitive ways including ...

Intercomparison and validation of the mixed layer depth fields of global ocean syntheses

Effects of high-frequency wind sampling on simulated mixed layer depth and upper ocean temperature

[1] Effects of high-frequency wind sampling on a near-global ocean model are studied by forcing the model with a 12 hourly averaged wind product and its 24 hourly subsamples in separate experiments. The differences in mixed layer depth and sea surface temperature resulting from these experiments are examined, and the underlying physical processes are investigated. The 24 hourly subsampling not ...

Processes that influence sea surface temperature and ocean mixed layer depth variability in a coupled model

A 50-year coupled atmosphere-ocean model integration is used to study sea surface temperature (SST) and mixed layer depth (h), and the processes which influence them. The model consists of an atmospheric general circulation model coupled to an ocean mixed layer model in ice-free regions. The midlatitude SST variability is simulated fairly well, although the maximum variance is underestimated an...
