Sentences with phrase «snowfall increased as»

Not exact matches

An increase in snowfall has long been predicted as a result of global warming.

Water managers see cloud seeding as a potential way of increasing winter snowfall.

It needs to be clarified here, that it is hypothetically possible to get more snowfall and snowpack in a globally warming world (at least for a while), due to increased precipitation (which is predicted in a warming world, esp for the higher latitudes) coming down as snow.

In all but one case, snowfall has increased as ice volume has fallen.

Previous research by Box using ice cores — long cylinders drilled out of the ice sheet that let scientists sample hundreds of years of ice layers — showed that in the past, snowfall has increased over the ice sheet as temperatures have risen.

The likelihood of snowfall making an appearance also increases as the month develops, starting off at 10 % on December 1st and rising up to 22 % by December 31st.

As for precipitation, [Moelg and Hardy, 2004] tentatively conclude that the glacier might be in positive mass balance if snowfall were increased to its 1880 maximum rate, even if temperature is held fixed at its present value.

2) In many scenarios, warming results in increased snowfall resulting in glacier lengthening as a direct result of climate warming.

One might think that more precipitation would then lead to more snowfall in regions such as the Sierra Nevada, which gets air masses saturated with oceanic moisture, but with the increasing temperatures at altitude, the precipitation is as rain, or if as snow, doesn't last as long.

Not surprisingly, we see a long - term increase in lake effect snowfalls as temperatures have warmed during the last century (see figure below).

This should be put into context, as Zwally also says that within a couple of decades (should the current loss rate remain) the losses will catch up to the gainings: «If the losses of the Antarctic Peninsula and parts of West Antarctica continue to increase at the same rate they've been increasing for the last two decades, the losses will catch up with the long - term gain in East Antarctica in 20 or 30 years — I don't think there will be enough snowfall increase to offset these losses.»

I can certainly see that SOME CO2 level would do that, but everything I have read so far about Antarctic says that in a somewhat warmer climate, which we will have in Antarctica soon, Antarctic as a whole will get more snowfall, hence more retention of ice, because warmer air holds more water vapor, even if the increase in warmth is merely from minus 40 C to minus 35 C.

The effects water vapor as evidenced by the increase in the amount of snowfalls and floods should also be discussed.

Snowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely diSnowfall varies across the region, comprising less than 10 % of total precipitation in the south, to more than half in the north, with as much as two inches of water available in the snowpack at the beginning of spring melt in the northern reaches of the river basins.81 When this amount of snowmelt is combined with heavy rainfall, the resulting flooding can be widespread and catastrophic (see «Cedar Rapids: A Tale of Vulnerability and Response»).82 Historical observations indicate declines in the frequency of high magnitude snowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely disnowfall years over much of the Midwest, 83 but an increase in lake effect snowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely disnowfall.61 These divergent trends and their inverse relationships with air temperatures make overall projections of regional impacts of the associated snowmelt extremely difficult.

For the entire Northern Hemisphere, there is evidence of an increase in both storm frequency and intensity during the cold season since 1950,1 with storm tracks having shifted slightly towards the poles.2, 3 Extremely heavy snowstorms increased in number during the last century in northern and eastern parts of the United States, but have been less frequent since 2000.11,15 Total seasonal snowfall has generally decreased in southern and some western areas, 16 increased in the northern Great Plains and Great Lakes region, 16,17 and not changed in other areas, such as the Sierra Nevada, although snow is melting earlier in the year and more precipitation is falling as rain versus snow.18 Very snowy winters have generally been decreasing in frequency in most regions over the last 10 to 20 years, although the Northeast has been seeing a normal number of such winters.19 Heavier - than - normal snowfalls recently observed in the Midwest and Northeast U.S. in some years, with little snow in other years, are consistent with indications of increased blocking (a large scale pressure pattern with little or no movement) of the wintertime circulation of the Northern Hemisphere.5 However, conclusions about trends in blocking have been found to depend on the method of analysis, 6 so the assessment and attribution of trends in blocking remains an active research area.

If snowfall increases (as in some models), the mass of ice in Greenland and Antarctica may increase, even if there is more melting and calving of icebergs at the edges.

«As it turns out, the scientific community has been addressing this particular question for some time now and they say that increased heavy snowfalls are completely consistent with what they have been predicting as a consequence of man - made global warming.&raquAs it turns out, the scientific community has been addressing this particular question for some time now and they say that increased heavy snowfalls are completely consistent with what they have been predicting as a consequence of man - made global warming.&raquas a consequence of man - made global warming.»

No matter how much they identify natural climate changes as unnatural they are confronted with the fact of declining temperatures and increasing snowfall.

Such models also indicate that warming would initially cause the Antarctic ice sheet as a whole to gain mass owing to an increased accumulation of snowfall (*; some recent studies find no significant continent - wide trends in accumulation over the past several decades; Lemke et al., 2007 Section 4.6.3.1).

As the Arctic sea ice melts, the water vapor delivered into the the atmosphere increases in the polar region, and so does the snowfall, so that the whole thing starts over again.

Furthermore, IPCC just as clearly states «Current global model studies project that the Antarctic ice sheet will remain too cold for widespread surface melting and is expected to gain in mass due to increased snowfall.»

Monaghan et al. further note «recent literature suggests there has been little overall change in Antarctic near - surface temperature during the past 5 decades» and «the absence of widespread Antarctic temperature increases is consistent with studies showing little overall change in other Antarctic climate indicators during the past 50 years such as sea ice area and snowfall.»

Hull (1897), noting that «the increased snowfall which would thus be caused... would tend to intensify the cold,» p. 107; deflection of currents was likewise seen as central in the scheme of Croll (1875).

As summarized in, for example, Meehl et al. (2007b), warming is expected to increase snowfall in the colder parts of Greenland and in Antarctica, and to increase melting in the warmer parts of Greenland.

As the companion article to this one points out, virtually every major prediction of catastrophe that global - warming alarmists have made about the coming state of the environment over the past several decades — from melting sea ice and flooded nations to loss of snowfalls and increased climate refugees — has proven utterly incorrect.

Clouds and Snowfall have increased as this warming took place.

As firn is buried beneath subsequent snowfalls, density is increased as air spaces are compressed due to mechanical packing as well as plastic deformatioAs firn is buried beneath subsequent snowfalls, density is increased as air spaces are compressed due to mechanical packing as well as plastic deformatioas air spaces are compressed due to mechanical packing as well as plastic deformatioas well as plastic deformatioas plastic deformation.

-- First we increase the greenhouse gases — then that causes warming in the atmosphere and oceans — as the oceans warm up, they evaporate more H2O — more moisture in the air means more precipitation (rain, snow)-- the southern hemisphere is essentially lots of water and a really big ice cube in the middle called Antarctica — land ice is different than sea ice — climate models indicated that more snowfall would cause increases in the frozen H2O — climate models indicated that there would be initial increases in sea ice extent — observations confirm the indications and expectations that precipitation is increasing, calving rates are accelerating and sea ice extent is increasing.

and ii) The Southern Ocean is freshening because of increased rain and snowfall as well as an increase in meltwater coming from the edges of Antarctica's land ice (Zhang 2007, Bintanga et al. 2013).

Two decades ago, the Greenland ice sheet was in approximate balance - ice loss at the edges as glaciers calved into the ocean was balanced by ice gain in the interior from increased snowfall.

In all but one case, snowfall has increased as ice volume has fallen.

They face breeding issues on land as temperatures rise and meltwater from snowfall and glaciers increases, increasing the chances their eggs will get washed away.

While the researchers show that the Karakoram will receive consistent — and perhaps increased — snowfall through 2100, more modeling work is needed to understand how the existing glaciers may change over time as a result of melt, avalanches and other factors, Kapnick said.
