When the wind - driven ocean circulation is intense, such as during the negative phase of the IPO & La Nina, there is strong upwelling of cold deep water along the equator, and along the eastern coasts of the continents.

During the positive AO phase there is little mixing of atmospheric masses between the Arctic and lower latitudes (mid-latitudes and subtropics) so the cold air stays bottled up in the Arctic and mild air dominates the mid-latitudes.

- Notice, during the current cold phase, there has been permanent ice caps in Antarctica for only 10 million years and at the North Pole for less than 5 million years (demonstrating that ice caps are a rare event in Earth's history, which shows we are in a cold phase)- Notice that the planet has had no ice caps — therefore it has been much warmer than now — for about 80 % of the past 500 million years.

If ocean oscillations are as powerful a climate driver as the anti-CO2 alarmists claim then this graph suggests a simple story: that cold Pacific surface waters swallowed up a big gulp of warmth from 1940 - 1970, which the PDO then belched back up during its warm - phase in the 80s and 90s.

According to their modeling studies, the difference in the amount of incoming solar radiation, in this case, primarily in the ultraviolet (UV) wavelengths, during the minima and maxima of the 11 - yr solar cycle are large enough to produce a characteristic change in the winter circulation pattern of the atmosphere over North America... When the NAO is in its negative phase, more cold air can seep south from the Arctic and impact the lower latitudes of Europe and the eastern U.S., which helps spin up winter storm systems.

One is diminished wind chill, when winds aren't as strong as usual, or as cold, or as dry — as is the case in the Labrador Sea during the negative phase of the North Atlantic Oscillation.

At present, the Pacific shifts erratically and frequently between warm and cold phases, but paleoclimate data indicates that, even during the Holocene, there were extended periods when it was stuck in one phase or the other.

During this period the PDO had flipped to the «cold» phase, and the AMO was dropping.

[*) Another contributing factor to a dominantly positive phase for the NAO index is current and expected SST anomaly, with relatively cold waters west of the Azores, favouring high pressure build - up there, and relatively warm waters off the US - Canadian east coast, favouring northerly Atlantic depression formation (especially during offshore winds).]

Just because the trees in cold climates are relatively widely spaced does not mean they do not differ in their rate of growth during their juvenile phase.

The pattern is also associated with the negative phase of the Arctic Oscillation, which is the dominant atmospheric pattern observed during severe winters and comprises a weakened jet stream and more cold air intrusions southward from the Arctic into North America and Eurasia.
