Sentences with phrase «precession causes»

As I noted above, DS proposal is that precession causes a warmer spring and day with the rest of warming following.

Not exact matches

The precession of the equinoxes is caused by the differential gravitational forces of the Sun and the Moon on the Earth.

In particular, there was no sign of climate change in Indonesia associated with Earth's orbital precession, a wobble caused by Earth's axis tilt that generates differences in sunlight in a 21,000 - year cycle.

«To our surprise, these motions turned out to be so strong that they caused the disk to fatten up and the disk precession to stop.

Firing an ultra-fast laser pulse at the material may completely flip the spin direction, reversing the magnetism, or may disrupt the spins, causing a kind of wobbling known as spin precession.

[25] Also the observed position angles of the stars are also subject to small cumulative changes (additional to position angle changes caused by the Precession of the Equinoxes), as first determined by W. H. van den Bos in 1926.

In addition, they could track the jets» precession, the movement caused by the disk's wobble.

It is believed that the PETM was likely initiated by changes of the orbital parameters of the Earth (eccentricity, obliquity and precession of axis) causing an increase in the intensity and distribution of solar radiation reaching the earth (Sexton et al, 2011).

That will cause at least additional precession of the line of apsides and the line of nodes.

I saw of graph of the precession cycle once and it appeared to occasionally skip a beat — perhaps when eccentricity got near zero — this makes some intuitive sense at least... (cause of Obliquity cycle is less obvious than precession of axis; perhaps some contribution comes from the Earth - Moon orbit and Earth + Moon — Sun orbit not being in the same plane — although the Moon's orbit will «average» near the plane of the Earth - Sun orbit over a relatively short time, but there's lunar orbit eccentricity, etc,... residuals might build up...?

Vetoretti and Peltier (2004) found that glacial inceptions can be caused either by a strong obliquity forcing or by a combination of eccentricity - precession forcing and low CO2 values, which is in line with results from Berger and Loutre (2001) who found that CO2 is important during times like the MIS - 11, when the insolation variations are too small to drive glacial - interglacial cycles.

While it is possible that the less significant, and originally overlooked, inclination variability has a deep effect on climate, [11] the eccentricity only modifies insolation by a small amount: 1 — 2 % of the shift caused by the 21,000 - year precession and 41,000 - year obliquity cycles.

The small changes in insolation will cause earlier and more extensive spring melting of Arctic ice, and indeed less ice formation over winter because northern winters are now shorter and milder than they were in 1750, due to apsidal precession.

«The precession of perihelion therefore is causing not only the nature of the seasons to alter, through the intensity of the sunlight arriving at the Earth changing for corresponding times of year, but also the lengths of the seasons are varying for the same reason.

Who amongst the readers out there can honestly say that they knew how apsidal precession is causing the lengths and the natures of the seasons to change?

An obliquity peak — thermally lagged by 6,500 years, coinciding with a peak of precession modulation / eccentricity, causes an interglacial.

The precession of the axes of the Earth causes some swing of the temperature up and down but the general tendency is the decrease of temperature and this tendency seems to be retained.

If scientists then want to start arguing that its different this time we can then have a sensible discussion about the earths precession, or our orbit, which combined with a minor GHG they think will cause problems.

The precession cycle causes the seasons to migrate, which is why it is also called the Precession of the Equinoxes — and why the Age of Pisces will eventually pass the torch to the Age ofprecession cycle causes the seasons to migrate, which is why it is also called the Precession of the Equinoxes — and why the Age of Pisces will eventually pass the torch to the Age ofPrecession of the Equinoxes — and why the Age of Pisces will eventually pass the torch to the Age of Aquarius.
