Sentences with phrase «northward heat transport»

To the north of the deep mixed layers, eddy processes drive the warming and account for nearly 80 % of the northward heat transport anomaly.

The AMOC has a considerable influence over European climate from the northward heat transport by the Gulf Stream and a slowdown or halt of the AMOC could have a large impact on climate and even induce abrupt climate changes (Alley et al, 2002; Alley, 2007).

All of these characteristics (except for the ocean temperature) have been used in SAR and TAR IPCC (Houghton et al. 1996; 2001) reports for model - data inter-comparison: we considered as tolerable the following intervals for the annual means of the following climate characteristics which encompass corresponding empirical estimates: global SAT 13.1 — 14.1 °C (Jones et al. 1999); area of sea ice in the Northern Hemisphere 6 — 14 mil km2 and in the Southern Hemisphere 6 — 18 mil km2 (Cavalieri et al. 2003); total precipitation rate 2.45 — 3.05 mm / day (Legates 1995); maximum Atlantic northward heat transport 0.5 — 1.5 PW (Ganachaud and Wunsch 2003); maximum of North Atlantic meridional overturning stream function 15 — 25 Sv (Talley et al. 2003), volume averaged ocean temperature 3 — 5 °C (Levitus 1982).

The reduction in northward heat transport warmed the Southern Hemisphere due to a process commonly referred to as the bipolar - seesaw (e.g., Clark et al., 2002).

It appears based on ship - borne measurements that northward heat transport has decreased by 20 % in the North Atlantic.

It then turns into the North Atlantic Drift which is really the flow of water responsible for the anomalous northward heat transport in the Atlantic.

Not exact matches

The THC actually transports a positive net amount of heat northward across the equator from the South Atlantic to the North Atlantic.

This northward transport of heat is exactly what we understand is required to weaken the polar vortex.

It is shallow so transports a lot of heat northward.

Continued operation of the oceanic conveyor belt is important to northern Europe's moderate climate because of northward transport of heat in the Gulf Stream and North Atlantic Current.

Based on various paleoclimate proxies and model results, it has been suggested that the input of freshwater into the North Atlantic following these events led to slowdowns of the Atlantic meridional overturning circulation (AMOC) and reductions of its considerable northward cross-equatorial heat transport.

While the circulation of the Atlantic Ocean has a complex three - dimensional spatial structure, the zonally integrated flow in the basin, referred to as the Atlantic Meridional Overturning Circulation (AMOC), is largely responsible for the net northward oceanic heat transport on climate - relevant timescales.

Zhang and Delworth and Zhang et al. showed by using models that, as the northward surface heat transport by the AMOC is increased, the global atmospheric heat transport decreases in compensation (and vice versa), providing a multidecadal component to the Pacific Decadal Oscillation (PDO).

Barreiro et al. (2008) found that northern Atlantic waters have freshened rapidly in the past few decades and heat transported northward by the thermohaline circulation has decreased.

Heat from anomalously warm ocean temperatures is transported vertically and eventually northward by unusually active tropical convection (thunderstorms), warming the upper atmosphere in the lower latitudes.

Northward ocean heat transport achieved by the AMOC is responsible for the relative warmth of the Northern Hemisphere, compared to the Southern Hemisphere, and is thought to play a role in setting the mean position of the Inter-Tropical Convergence Zone north of the equator.

Temperatures in the neighboring deep ocean are moderated by strong northward transport of heat in the Gulf Stream, which begins to veer eastward before reaching Georges Bank.
