Sentences with word «diapycnal»

In addition, the amount of diapycnal mixing, which is used for numerical stability in this class of ocean models, will also be reduced as the grid spacing becomes smaller.

Quantify the magnitude, location, and physical mechanisms associated with interior diapycnal mixing in the ocean, which contribute to the diabatic AMOC, and evaluate the realism of current GCMs in this regard.

The researchers used data from the «Diapycnal and Isopycnal Mixing Experiment in the Southern Ocean» (DIMES) project, a UK / US field program aimed at measuring diapycnal and isopycnal mixing in the Southern Ocean.

Quantify the magnitude, location, and physical mechanisms associated with interior diapycnal mixing in the ocean, which contribute to the diabatic AMOC, and evaluate the realism of current ocean GCMs in this regard.

We find that over a wide range of values of diapycnal diffusivity and Southern Ocean winds, and with a variety of changes in surface boundary conditions, the spatial patterns of ocean temperature anomaly are nearly always determined as much or more by the existing heat reservoir redistribution than by the nearly passive uptake of temperature due to changes in the surface boundary conditions.

The theory shows that dynamics of the overturning circulation can be characterized by two limiting regimes, corresponding to weak and strong diapycnal mixing.

This combination of diapycnal and isopycnal mixing drives the upwelling of deep waters up to the surface, forming an «upper» and «lower» overturning cell.

The numerical experiments are designed to explore the effects of changing various properties of the ocean (its size, geometry and diapycnal diffusivity), the atmosphere (its water vapour content) and the forcing of the system (the distribution of incoming solar radiation and the rotation rate of the planet).

Because the ocean is made up of many layers of water that are dependent on temperature and salinity, water moves easily along horizontal or «isopycnal» layers, but mixes only slowly across the layers, known as «diapycnal» mixing.

The researchers took measurements of small - scale temperature and velocity fluctuations, to measure the diapycnal movements in the Antarctic Circumpolar Current (ACC) across the Drake Passage region of the Southern Ocean.

Woodgate, R.A., K. Aagaard, J.H. Swift, K.K. Falkner and W.M. Smethie,» Pacific Ventilation of the Arctic Ocean's lower halocline by upwelling and diapycnal mixing over the continental margin `, Geophysical Research Letters, 32, L18609, doi: 10.1029 / 2005GL023999, 2005.

Sun, S., and R. Bleck, 2006: Geographic distribution of the diapycnal component of thermohaline circulations in coupled climate models.
