Sentences with phrase «ice feedbacks»

Introducing the snow / ice feedback also affects the amount of energy trapped by water vapour.

Runaway ice feedbacks drive the transitions between glacial and interglacial states seen repeatedly over the past 2.58 million years.

The cooling was sustained after the aerosols had left the atmosphere by a sea - ice feedback in the North Atlantic Ocean, the researchers believe.

Several ocean - air - sea ice feedback processes may be operating (Meredith and King 2005; Hanna 1996), though it has been difficult to pin down their relative roles in the observational studies (King 1994; Jacobs and Comiso 1997).

This sea ice feedback at 18K is consistent with the smaller fsnow / ice ∼ 1.1 in the So and CO2 experiments, which applied to a warmer earth with less sea ice.

With a small decrease in radiation from the Sun — or an increase in ice cover — the system becomes unstable with runaway ice feedbacks.

Understanding and evaluating sea ice feedbacks is complicated by the strong coupling to polar cloud processes and ocean heat and freshwater transport.

The new study shows that climate sensitivity to historical changes in the abundance of aerosol particles in the atmosphere is larger than the sensitivity to CO2, primarily because the aerosols are largely located near industrialized areas in the Northern Hemisphere middle and high latitudes where they trigger more rapid land responses and strong snow & ice feedbacks.

This project will advance our understanding of seasonal ice zone (SIZ) cloud - ice feedbacks and our ability to forecast SIZ weather and ice conditions through the combination of carefully designed model experiments, observations, and technology developments which are targeted to validate and improve the models.

Times like this in the past have triggered runaway ice feedbacks that culminate in kilometre deep ice sheets over much of Europe and North America.
