high latitudes, more accurately, so that among other things they can be taken
into account in the design and operation of future communications systems,» explains Per Høeg.
Warm and saline water transported poleward cools at the surface when it reaches
high latitudes and becomes denser and subsequently sinks
into the deep ocean.
Furthermore, the relatively
high «sensitivity» from glacial to interglacial is largely driven by the change in the orbit relative to the Sun, which changes the distribution of incident solar energy
into the system quite dramatically (more energy is distributed to the
higher latitudes in the NH summer, in particular).
eg «These studies provide new insights on the sensitivity and response of meridional ocean circulation to melt water inputs to the North Atlantic
high latitudes (e.g., Bamberg et al., 2010; Irvali et al., 2012; Morley et al., 2011) and their potential role in amplifying small radiative variations
into large a climate response through dynamic changes in ocean - atmosphere interactions (e.g., Morely et al., 2011; Irvali et al., 2012; Morley et al., 2014).
The surface waters of the tropical Atlantic are then transported, via the Gulf Stream, towards the
high latitudes where they warm the atmosphere before plunging
into the abysses in the convection zones situated in the seas of Norway, Greenland and Labrador.
The Atlantic Ocean circulation that carries warmth
into the Northern Hemisphere's
high latitudes is slowing down because of climate change - and is at its weakest point in the past 1,600 years.
Generally speaking things look bad, what with the West Antarctic ice sheet slip - sliding away
into the tropics, the Greenland glaciers retreating, animals beating a retreat to the coolth of
higher altitudes and
latitudes, and a host of other apocalyptic signals.
For example, the CLOUD experiments could provide insights
into the rate of tropical cloud formations which effect tropical cooling and the heat transfer from the tropics to the
higher latitudes.
The gyres spin up with negative polar annular modes —
high pressure at the poles push circumpolar wind and storms
into lower
latitudes.
At
high latitudes, they sink deep
into the ocean basins.
The circulation change extends
into the Northern Hemisphere, producing cooling at
high northern
latitudes.
The negative state involves relatively
high pressure at the pole pushing winds, cold air and storms
into lower
latitudes.
For almost the entire winter, sea ice has been reluctant to form there, and now that the Sun has returned, the ice edge has started to retreat to record
high latitudes, past the Bering Strait all the way up
into the Chukchi Sea.
Nature finds its own balances such as increased phyto plankton, increased sea surface, the carbon absorbing treeline limit moving to
higher latitudes bringing more CO2 absorbing trees
into the game, increased rainfall etc..
Higher surface pressure at the pole pushes winds and polar storms
into lower
latitudes.
During the winter months in middle and
high latitudes, the lower parts of the troposphere over continents often serve as reservoirs of cold air as heat is radiated
into space throughout the long nights.
Rapid ice drift is an important factor in regional ice conditions, especially redistribution of multiyear ice
into areas with
high melt rates at low
latitudes.
Even that which falls on land at
higher latitudes tends to be carried toward the sea on north - flowing rivers, and so
into the already somewhat less salty Arctic Ocean.
The region of lower pressure brings cooler air from the
higher latitudes into the eastern U.S.,» explained Singh.
Higher pressure will push winds and storm tracks
into lower
latitudes.
For example, Gavin's Pussycat has already pointed out that in their analysis they did not take
into proper account how polar amplification results in larger swings in temperature at
higher latitudes — and that when estimating temperature variation at lower
latitudes on the basis of proxies at
higher latitudes one has to scale down the variation, that is recognize that the swings in temperature will be smaller at those lower
latitudes.
Woody boreal vegetation is expected to spread
into tundra at
higher latitudes and
higher elevations (Grace et al., 2002; Kaplan et al., 2003; Gerber et al., 2004).
When a large surge of polar air moves equatorward it draws a pulse of energy from the oceans in the lower
latitudes and pumps it
into the stratosphere where most of that energy is pushed out to space but a portion is not pushed out and descends again thus strengthening the
high pressure systems on the poleward side of the mid latitude jets.
The effects of snow cover are intricately woven
into the «Arctic Oscillation» (this is a pressure pattern in the mid to
high latitudes).
The result is warming of the tropics and of the
highest latitudes (but the latter stay below the freezing point of water) and a flow of cold
into the mid
latitudes and more precipitation in the form of snow at lower
latitudes than normal.
A new study in the Arctic north shows that water at the
higher latitudes are undergoing as serious changes as other areas, but they're changing at an even faster rate.Physorg writes that researchers from nine European countries have turned a coal mine village off the coast of Ny - Aalesund, just shy of 750 miles from the North Pole,
into a laboratory site during July in a major effort to understand how ocean acidification is altering the northern water.
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.
That 1.1 C is the IPCC low end «sensitivity» estimate which isn't a scary number at all and in fact is a great number because if that's all it is then the slight warming, mostly in the winter in the
higher latitudes, is a great boon to agriculture especially when the biological effect of
higher CO2 on green plant growth rates and water consumption is taken
into consideration.
-- Tropical — occur near the equator, in low
latitudes — Temperate — occur about halfway between the equator and the poles, in the middle
latitudes — Polar — occur near the poles, in the
high latitudes — Dry — occurs at many different
latitudes — Highland — occurs at many different
latitudes Geographers divide some climate zones
into more specific climate regions.
