Sentences with phrase «ice thickness growth»

Not exact matches

However, sea ice then grows very rapidly, since the growth rate for thin ice is much higher than for thick ice, which acts as a negative feedback on thickness during the growth season (Bitz and Roe, 2004; Notz, 2009).

The sea ice component represents sea ice in multiple categories of thickness and accounts for changes in thickness due to growth and melt as well as mechanical deformation of ice (Thorndike et al. 1975, Hibler 1980).

Perhaps the ice extent in summer is conditioned by the rapid growth rate and thickness of the newly expansive regions of first - year sea ice?

Thickness surveys and drifting buoys that are part of the Arctic Observing Network (AON) suggest that much of the growth of first - year sea ice in the Pacific sector approaches an end - of - season thickness of around 1.7 m, independent of the starting time of freeze - up in the fall (H.

Even though the seasonal ice cover was formed later in the fall of 2007, the mean thickness of the FY ice cover at the end of March seems comparable to that of the previous two seasons because of lower snow accumulation and thus faster growth i.e., higher ice production.

Other in situ and satellite data suggest that even though the seasonal ice cover was formed later in the fall of 2007, the mean thickness of first year ice cover is comparable to that of the previous two seasons because of lower snow accumulation and lower air temperatures and thus, faster growth.

Understanding of other feedbacks associated with the cryosphere (e.g., ice insulating feedback, MOC / SST - sea ice feedback, ice thickness / ice growth feedback) has improved since the TAR (NRC, 2003; Bony et al., 2006).

It is shown that the release of solar heat stored following summer 2007 was sufficient to have reduced sea - ice thickness at the end of the 2008 growth season by about 25 %.

Some single - column model studies reveal bifurcation in the transition to seasonally ice - free conditions (Abbot et al., 2011; Merryfield et al., 2008; Flato and Brown, 1996) but others do not, due to the stabilizing effects of ice thickness on ice growth (Eisenman and Wettlaufer, 2009).

Simply extrapolating historical trends also does not account for feedbacks in the system, such as the negative ice thickness - ice growth rate feedback identified by Bitz and Roe (2004) that can slow the ice volume rate of loss.
