Sentences with phrase «isopycnals in»

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.

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?

Not exact matches

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).

For a rough estimate, downwelling water to the deep ocean in convection zones is about 40 Sv (10 ^ 6 m3 / s), assuming that comes in with say 2 deg C, and leaves (through upwelling, isopycnal and diapycnal diffusion), that is a heat flux of 320 TW, thus at least an order of magnitude larger than the geothermal fluxes.

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.

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.

Mesoscale mixing is parameterized according to the Gent - McWilliams scheme, although the along - isopycnal flux was misaligned resulting in excessive cross-isopycnal diffusion.

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.
