Sentences with phrase «for subpolar»

Not exact matches

One week ago, we published a paper in Nature Climate Change (which had been in the works for a few years) arguing that the cold in the subpolar North Atlantic is indicative of an AMOC slowdown (as discussed in my last post).

If I instantly quadruple CO2 in an experiment, I'd expect ocean heat uptake (OHU) to occur pretty uniformly in latitude for the initial few years, but then become pretty localized to the subpolar oceans after, say, year 100.

My main argument that speaks for an anthropogenic influence is the long - term downward trend since 1930 inferred from the SST data in the subpolar Atlantic, and the fact that climate models driven by anthropogenic forcing predict just such a relatively cold patch in this same area.

A region in the subpolar Atlantic has cooled over the past century — unique in the world for an area with reasonable data coverage (Fig. 1).

The evidence for this is the trend towards cooling in the subpolar North Atlantic which anti-correlates with temperatures in the South Atlantic (suggesting reduced heat transport from the South Atlantic to the North Atlantic).

If I instantly quadruple CO2 in an experiment, I'd expect ocean heat uptake (OHU) to occur pretty uniformly in latitude for the initial few years, but then become pretty localized to the subpolar oceans after, say, year 100.

You can make contact with some of the concepts of «efficacy» and also retain a global mean perspective (see e.g., Hansen's work on the efficacy of climate forcing, or Kate Marvel's work looking at how 1 W / m2 expresses itself in different ways for different forcings) by noting that efficacy > 1 for OHU that is maximized in subpolar areas.

Model simulations for the North Atlantic Ocean and thermodynamic principles reveal that this feedback should be stronger, at present, in colder midlatitude and subpolar waters because of the lower present - day buffer capacity and elevated DIC levels driven either by northward advected surface water and / or excess local air - sea CO2 uptake.

Mass balance of mountain and subpolar glaciers: A new global assessment for 1961 - 1990.

The strength of the Icelandic Low is the critical factor in determining path of the polar jet stream over the North Atlantic In the winter the IL is located at SW of Greenland (Subpolar Gyre) In summer the IL is to be found much further north (most likely the North Icelandic Jet, formed by complex physical interactions between warm and cold currents) These two run under two different regimes and two clocks (see the CET synthesis from 3 harmonics, one for each summer and winter, and one common — see the above link, bottom graph).

not entirely clear, but since it is the north leg of the NAO (Icelandic pressure) that is determinant, it presumably takes some years for the warm atlantic currents to reach the Arctic and return as cold currents via Denmark Strait (Icelandic pressure) and few more years to loop into the subpolar gyre to initiate AMO oscillation Hence in order of occurrence NAP > NAO > AMO (refer to http://www.vukcevic.talktalk.net/NAOn.htm one but last illustration) Just as a reminder compare NAP waveform with the CET spectrum components (1660 - 2021) http://www.vukcevic.talktalk.net/CET-NV.htm I hope some of the above helps, but if not than your «how you cook up your «secret recipe» NAP misgiving is by far safer than accepting «blanco» assurance.

NASA's climate experts are on record for predicting all sorts of climate catastrophes, including extreme warming of the world's «higher» latitudes (the world's polar / subpolar regions).

Finally, Clement et al. note that the argument for a role for ocean dynamics, namely the AMOC, pertains to a particular region of the subpolar gyre.

These range from few years (Beaufort gyre 4 years, Circumpolar current 8 years, Indian ocean gyre 10 years, N. Atlantic subpolar gyre 20 years etc.) up to above 100 years for some of the Pacific gyres, and finally the great ocean conveyor belt estimated at ~ 1600 years.

The sediments do not provide a unique sedimentary facies model for high - latitude subpolar glaciers and are indistinguishable from temperate examples.

The highest values of the uncertainties associated with the interpolation / extrapolation into unsampled grid boxes are found in subpolar latitudes of both hemispheres for the turbulent fluxes, where they can be comparable with the sampling errors.
