Sentences with phrase «ice extent number»

Why don't you publish a global sea ice extent number?

Please note that the Arctic sea ice extent number for 2016 is preliminary — changing winds could still push the ice extent lower.

Although you really can't check this assertion since the data is not really available anywhere — the Cryosphere has some charts of sea ice area but where are the numbers — where are the sea ice extent numbers.

At this time of year, sea ice extent numbers are meaningless for polar bears.

Rob's correlation work demonstrates that «the June land snow cover signal is clearly present in the September ice extent numbers.»

Not exact matches

Complementary analyses of the surface mass balance of Greenland (Tedesco et al, 2011) also show that 2010 was a record year for melt area extent... Extrapolating these melt rates forward to 2050, «the cumulative loss could raise sea level by 15 cm by 2050 ″ for a total of 32 cm (adding in 8 cm from glacial ice caps and 9 cm from thermal expansion)- a number very close to the best estimate of Vermeer & Rahmstorf (2009), derived by linking the observed rate of sea level rise to the observed warming.

Though slightly larger than last year, the minimum sea ice extent 2017 is average for the past ten years and far below the numbers from 1979 to 2006.

A number of recent studies linking changes in the North Atlantic ocean circulation to sea ice extent led Yeager to think that it would also be possible to make decadal predictions for Arctic winter sea ice cover using the NCAR - based Community Earth System Model...

... The numbers of sea ice extent in this site are estimates calculated by certain algorism.

Specifically, I use a formula based on physics of energy absorption, using snow cover, and June ice extent / area numbers.

Ice around Iceland (the number of weeks when ice was observed in this case) must correlate very well with the arctic sea ice extent / area, at least with the annual maximIce around Iceland (the number of weeks when ice was observed in this case) must correlate very well with the arctic sea ice extent / area, at least with the annual maximice was observed in this case) must correlate very well with the arctic sea ice extent / area, at least with the annual maximice extent / area, at least with the annual maximum.

However, a number of models that have fairly thick Arctic sea ice produce a slower near - term decrease in sea ice extent compared to observations (Stroeve et al., 2007).

This sea ice area number will always be smaller than the number for sea ice extent, though it can approach it quite closely when the pack is well - defined, with nice neat edges.

The main preconditioning considered in our outlook is the area of robust multiyear ice in spring (April - May), the thickness of the FY ice as determined by the number of freezing degree days during winter / spring and the spring / summer total ice extent at the time of issue of the outlook.

If the increasing number of sunspots would bring the Arctic index into «a positive phase» as well, then temperature isolation of the High North would in the winters months improve compared to recent years [which brought temperature records over Greenland and the Arctic Ocean — and a smallest ice extent last winter], perhaps allowing for some extra sea ice recovery.

Although a number of scientists are hollering that 2017 was «among the warmest on record», we are not seeing any manifestation of this, at least over the northern hemisphere, where ironically snow and ice have shown surprising extents.

Extent is always a larger number than area, which measures just what is covered with ice.

Based on predictions of sea ice extent from climate change models, the penguins are likely to see their numbers plummet by 95 % by 2100.

A number of techniques have been employed to sub-set or recalibrate these projections based on different aspects of the observed ice cover, including the mean and / or seasonal cycle of ice extent (e.g., Stroeve et al., 2007, 2012a; Wang and Overland, 2009, 2012), historical ice cover trends (Boe et al., 2009), and ice volume and thin ice area (Massonnet et al., 2012).

However, a large percentage increase in a small number may not amount to a meaningful increase; sea ice extent currently remains well below the 1981 to 2010 average.

See the Shrinking Arctic Sea Ice The National Snow and Ice Data Center released preliminary numbers on the minimum extent of Arctic sea ice, calling this year's minimum the second lowest on recoIce The National Snow and Ice Data Center released preliminary numbers on the minimum extent of Arctic sea ice, calling this year's minimum the second lowest on recoIce Data Center released preliminary numbers on the minimum extent of Arctic sea ice, calling this year's minimum the second lowest on recoice, calling this year's minimum the second lowest on record.

Nevertheless, as I have said, the impact of the reductions in Arctic sea ice extent, which we have seen in the last few years on our winter climate, is only one of a number of factors, and certainly last year was probably not the dominant factor.

I think it is really important to make that distinction - that there are a number of factors that influence the extent of Arctic sea ice, some of them of course associated with changes in the radiative forcing from the atmosphere, as a result of anthropogenic greenhouse gases and aerosols, but also changes in the atmospheric circulation and also the advection of heat into or out of the Arctic by the ocean circulation.

It should be noted that this number represents a monthly average and is dependent on a particular passive microwave algorithm to derive ice concentration (see the CliC Arctic Sea Ice Working Group note on the accuracy of satellite - derived passive microwave estimates of sea ice extenice concentration (see the CliC Arctic Sea Ice Working Group note on the accuracy of satellite - derived passive microwave estimates of sea ice extenIce Working Group note on the accuracy of satellite - derived passive microwave estimates of sea ice extenice extent).

In early summer, the first to third week of July, employees make guesses about the minimum daily ice extent, which is a slightly lower number than the monthly mean extent targeted by SIO and NCAR.
