The deepening of the Drake Passage resulted in a change in ocean circulation that resulted in warm waters being directed northwards in
circulation patterns like those found in the Gulf Stream that currently warms northwestern Europe.
Not exact matches
This variability includes the Pacific Decadal Oscillation (PDO), a long - lived El Niño -
like pattern of Pacific climate variability that works
like a switch every 30 years or so between two different
circulation patterns in the North Pacific Ocean.
[Response: Well, something
like a
circulation changed forced by the NAO
pattern (which may in turn be affected by greenhouse gases) might cause an increase in European air temperatures, which in turn would allow low level moisture to increase if there is enough moisture supply, which would then constitute an amplification of a signal driven remotely.
All around the tropics is a
pattern of rising and sinking air —
like a vertical loop — called the Walker
Circulation.
Would somebody here,
like to explain to me how we can lose Arctic Sea ice (in part or in whole) without changing the atmospheric
circulation patterns?
Alley is talking mainly about D / O events and,
like some others (Broecker for instance) tried to link it to the LIA, but neither the
pattern of change, the abruptness, the ocean
circulation change nor the magnitude actually match.
Now that we know much more than we did about ocean
circulation patterns, intermixing and the
like (although there is still much to learn) we need to get this message across in much simpler fashion than we have done so far.
Expecting less than 5 % of Earths surface to filter the air mass from the other 95 % given actual air
circulation patterns is patently absurd compared to natural CO2 scrubbing mechanisms
like the biological carbon cycles, or Henry's law (which is leading to ocean acidification.
It is not surprising that there are many skeptics who
like I am, are very knowledgeable in many of the over lapping fields, of gas chromatography, anthropology, radio graphics of X-ray and particle physics, biological plant and animal processes, agriculture, high power radio transmission and reception, and its attendant multiplexing of signals, mining, reforestation plans and progress realities, nuclear, gas, and coal power plant construction techniques, organic gardening, astronomy, stellar physics, global
circulation pattern drivers, and have also spent considerable time out doors in a tent and sleeping bag.
Then there were other words
like «mass
pattern shift» and «wholesale change in anomalies» and «changes in global
circulation.»
«A climate
pattern may come in the form of a regular cycle,
like the diurnal cycle or the seasonal cycle; a quasi periodic event,
like El Niño; or a highly irregular event, such as a volcanic winter... A mode of variability is a climate
pattern with identifiable characteristics, specific regional effects, and often oscillatory behavior... the mode of variability with the greatest effect on climates worldwide is the seasonal cycle, followed by El Niño - Southern Oscillation, followed by thermohaline
circulation.»
By something similar I mean all kind of quasistationary modes
like circulation patterns that are formed, live for a considerable time and disappear or change form.
That is because there are factors,
like air and ocean
circulation patterns, that affect both the rate and the intensity of the global warming.
I agree with the overall scenario (and was actually thinking of posting something similar), except that I suspect that instabilities and the Earth's rotation would cause the
pattern to break up into relatively narrow latitudinal bands perhaps as little as a few tens of kilometres wide, with a sort of helical
circulation in each (
like a rope).
The atmosphere, too, has gotten its act together this time around — and is exhibiting a more strongly El Niño -
like circulation pattern than has ever been observed previously during the summer months.
A fundamental element of today's climate system is a conveyor -
like ocean
circulation pattern that distributes vast quantities of heat and moisture around our planet.
The models (and there are many) have numerous common behaviours — they all cool following a big volcanic eruption,
like that at Mount Pinatubo in 1991; they all warm as levels of greenhouse gases are increased; they show the same relationships connecting water vapour and temperature that we see in observations; and they can quantify how the giant lakes left over from the Ice Age may have caused a rapid cooling across the North Atlantic as they drained and changed ocean
circulation patterns.
Changes in the speed of the Atlantic
circulation pattern — known as Atlantic Meridional Overturning Circulation — that influences the world's oceans because it acts like a conveyor belt moving water around
