Sentences with phrase «orbital parameters for»

We also assess possible orbital parameters for each of the four planets independently.

Not exact matches

Kepler, which will keep a continuous watch on a patch of stars for more than three years, is better suited to finding planets like our own in terms of orbital periods as well as other parameters, although it will likely be a few years before it moves from the hot objects it has already discovered to cooler, potentially habitable worlds, whose transits are subtler and less frequent.

While natural global warming during the ice ages was initiated by increased solar radiation caused by cyclic changes to Earth's orbital parameters, there is no evident mechanism for correcting Anthropogenic Global Warming over the next several centuries.

Natural global warming is self - rectifying either by slow chemical weathering processes responsible for mineral sequestration of carbon or by gradual return of Earth's orbital parameters to what they were before the onset of global warming, thereby significantly reducing the amount of solar radiation reaching the Earth's surface.

The two objects [Sedna and 2012 VP113] have similar values for one of their orbital parameters: the angle [w] between the point of perihelion and where the orbit crosses the plane of the Solar System [from south to north].

Recent modelling work provides strong support for the important role of variations in the Earth's orbital parameters in generating long - term climate variability.

It is rapid, dramatic, and does not appear to allow for immediate regression to the earlier state when the external forcings (orbital parameters) return to their previous level.

So for the policy - relevant issues, we generally focus on the physical atmosphere - ocean system, sometimes with coupled carbon - vegetation system, and treat the major ice sheets, orbital parameters and planetary topography as fixed boundary conditions.

Just a quick note to say that the paleoclimate data for earlier warm periods 125,000 years ago and even 8 - 10,000 years ago in northern Alaska (paleoclimate warmer than now, [from] different forcings) document the northward advance of the treeline from Nome to Barrow, Alaska, and the Canadian border at different times of change in Earth's orbital parameters (without a significant change in CO2).

nc file for SSTs... Anyway, you might also want to add that changes to orbital parameters might be desirable.

Natural global warming is self - rectifying either by slow chemical weathering processes responsible for mineral sequestration of carbon or by gradual return of Earth's orbital parameters to what they were before the onset of global warming, thereby significantly reducing the amount of solar radiation reaching the Earth's surface.

But there will be perturbations, which probably account for the gradual synchronisation of the Moon's orbital parameters with other solar system frequencies.

Regular variation in the Earth's orbital parameters has been identified as the pacemaker of climate change on the glacial to interglacial time scale (see Berger, 1988 for a review).

Over several centuries, it may be possible to observe the effect of these orbital parameters, however for the prediction of climate change in the 21st century, these changes will be far less important than radiative forcing from greenhouse gases.»

The water and land locations were significantly different, as were the orbital dynamics — see Laskar et al (2010, etc) or Jack Wisdom (Google is your friend here) for the orbital parameters and other factors.

This ratio is a proxy for local summer insolation5, and thus allows the chronology to be constructed by orbital tuning without the need to assume a lag between a climate record and an orbital parameter.
