Sentences with phrase «of precessional»

If you think of the precessional cycle as four seasons instead of just the 65N TSI peak, you have Hot Summer / Cold Winter, Warm Spring / Cool Fall, Mild Summer / Mild Winter Cool Spring / Warm Fall.
Earth eccentricity cycles modulate the amplitude of precessional forcing of the African monsoonal rains (see upper right panel), and deep lake conditions are observed in several East African basins during some (not all) eccentricity maxima over the 5 Ma (deMenocal, 2011; Trauth et al., 2005; Kingston et al., 2007)
Actually, the oceans have a seesaw where the SH oceans warm more during this phase of the precessional cycle.
Raymo and Paillard have a good story about the 100KYr cycle arising from the modulation of the precessional cycle by the changes in the Earth's orbital eccentricity, coupled with some glacial dynamical effects which «rectify» the high frequency precessional signal.

Not exact matches

I am assuming the similarity of the «low eccentricity and consequently weak precessional forcing» in the current interglacial and during MIS 11.
The alignment of obliquity and eccentricity due to precession is a much stronger effect than for the Earth, leading to «great» summers and winters on time scales of tens of thousands of years (the precessional period is 170,000 years).
The main changes in radiative forcing from the precessional cycle are in the latitudinal and seasonal distribution, not in the global mean, which is why the nature of the response can be expected to be different from doubling CO2.
The alignment of obliquity and eccentricity due to precession is a much stronger effect than for the Earth, leading to «great» summers and winters on time scales of tens of thousands of years (the precessional period is 170,000 years).
The climate change in this period is generally believed to be associated with precessional changes in the distribution of solar radiation, which primarily affect land - sea temperature contrast, and give only a regional warming, plus an enhancement of certain monsoonal circulations.
That would account for the relative strengths of the obliquity and precessional signals in the data.
You'd better hope that the rebound from the coldest depths of the half precessional Holocene was natural, because if man did the heavy lifting of warming, then we really can't keep it up much longer.
The surface of the oceans are always warmer than the depths of the oceans > If you change the mixing efficiency, by shifting atmospheric circulations with solar precessional cycle for example, the mixing efficiency changes and the regions where precipitation falls changes.
And the much longer term ice - age and magnetic cycles may well be regulated by the Earth's precessional cycle (and this is not simply an effect of «geometry»).
Extreme weather is the name of the game when seven of the past eight interglacials underwent glacial inception at their half precessional ages.
The interglacial thus lasts an additional precessional cycle, yielding a total duration of 28 kyr.
