Sentences with phrase «overturning circulation increased»

Similarly, equatorial upwelling associated with the shallow meridional overturning circulation increased in the central Pacific, shoaling the thermocline and contributing to cooling trends in the mixed layer.

Not exact matches

Observations and the high - resolution climate model CM2.6 show a strong relationship between a weakening Atlantic Meridional Overturning Circulation (AMOC) and an increase in the proportion of warm - temperate slope water entering the U.S. Northeast Continental Shelf, primarily through the Gulf of Maine's Northeast Channel.

However, over longer terms, deep - water oxygenation may also increase even if Atlantic meridional overturning circulation becomes weaker, as deep convection in the Weddell Sea and Antarctic Bottom Water becomes enhanced (Yamamoto et al., 2015).

Both observations and the climate model demonstrate a robust relationship between a weakening Atlantic Meridional Overturning Circulation (AMOC) and an increase in the proportion of Warm - Temperate Slope Water entering the Northwest Atlantic Shelf.

«Recent Increases in Arctic Freshwater Flux Affects Labrador Sea Convection and Atlantic Overturning Circulation.»

Change in the overturning circulation likely contributes to expansion of subtropical conditions and increased aridity in the southern United States [30], [100], the Mediterranean region, South America, southern Africa, Madagascar, and southern Australia.

Suppression of ocean circulation overturning decreases the ocean heat flux available to melt ice, leading to an increase in net ice production [13].

But the temperature is actually controlled by the lapse rate because any infringement on the lapse rate causes the updrafts in the thunderstorm region to increase and immediately remove the excess heat by increasing the overturning circulation in the equatorial troposphere.

Stronger vertical mixing invigorates the MOC [Meridonal Overturning Circulation] by an order of magnitude, increases ocean heat transport by 50 — 100 %, reduces the zonal mean equator - to - pole temperature gradients by up to 6 °C, lowers tropical peak terrestrial temperatures by up to 6 °C, and warms high - latitude oceans by up to 10 °C.»

The researchers found that as external forcing increases in strength over the 21st century, sea level variability associated with the overturning circulation becomes dominant.

As the Earth warmed during the 1980s and»90s, it was observed that the convective overturning of the tropics (the Hadley circulation) increased.

Secondly, the freshening of Antarctic surface water induces a slowdown of the lower overturning circulation, leading to an increase of the biological carbon storage in the Southern Ocean.

The US AMOC Program, now in its ninth year, was developed as a US interagency program to increase understanding of the Atlantic Meridional Overturning Circulation in response to the fourth near - term priority of the SOST Ocean Research Priorities Plan.

Among the suite of circulation models examined here, the largest reduction in atmospheric pCO2 of 44 — 88 ppm occurs in a model where reduced overturning rates of both southern and northern sourced deep waters result in a four-fold increase in the Southern Ocean deep water ventilation age.
