Sentences with word «isopycnals»

Regarding the first part of your post, I'm well aware that dynamical forcing can shift the vertical position of isopycnals in the subtropical gyres.
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.
The salinity differences are differences along isopycnals that have been mapped to pressure surfaces.
An enhanced AMOC leads to a stronger cyclonic circulation north of the Gulf Stream and a southward shift of the Gulf Stream path, which results in shallower isopycnals (surfaces of constant density in ocean) in the Gulf Stream front.
Adiabatic isopycnal mixing schemes are now widely used.
The sum effect is to displace isopycnals (parcels of water of the same density) vertically in the column, i.e. the deep ocean warms.
Gridding sparse ocean observations onto a very high (in this case, 1 - by - 1 degree latitude x longitude) resolution is prone to producing some apparent structures that are simply artifacts of mathematical interpolation, even when isopycnal methods are utilised (this is common for gridding of data).
The transport process can be approximated by an equivalent diffusion process but, as I understand it, actually relies much more on isopycnal transport (along sloping surfaces of constant density), etc..
In the mixed layer and upper - mode - water regions, the divergent eddy fluxes are manifestly across isopycnals and so have a diabatic effect.
Lateral eddy mixing of tracers such as potential temperature and salinity is mainly directed along isopycnals, and has a small effect on the dynamics but is important for water mass properties.
This combination of diapycnal and isopycnal mixing drives the upwelling of deep waters up to the surface, forming an «upper» and «lower» overturning cell.
Nutrient concentrations are higher along the Gulf Stream path in response to the shallower isopycnals and have contributed to the enhanced chlorophyll concentrations around the Gulf Stream path.
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.
But in the absense of a global trend in the surface heat flux, wouldn't this be a regional phenomenon that would be compensated by a lifting of the isopycnals in other regions?
Depending on the method used to interpolate the data (along isopycnals or vertically by station), the estimated random uncertainty of the computed TC02 values in the Atlantic Ocean throughout the water column below the wintertime mixed layer depth ranges from ± 7.1 µmol / kg to ± 5.9 µmol / kg.
Thus, physical processes such as vertical and isopycnal mixing that drive large scale circulations need to be better understood to improve the predictive capability and accuracy of the models.
ESM2G is unique among for a global climate model, in that its ocean component employs an isopycnal - coordinate, in contrast to most global climate models, which use z - coordinate ocean components.
The AMOC structure (especially the depth of AMOC) and the deep overflow in the North Atlantic mean state are far more realistic in isopycnal - coordinate models with more realistic mixing than in z - coordinate models.
The eddy transport mechanism results from a reduction in both the diffusive and advective southward eddy heat transports, driven by decreasing isopycnal slopes and decreasing along - isopycnal temperature gradients on the northern edge of the peak warming.
