Sentences with phrase «more snowfall increases»

If not, throw them all out and look for something else, like, it snows more when oceans get warmer and more thawed and the more snowfall increases ice volume and more ice weight increases ice flow and the increased ice extent limits the upper bound of temperature and causes cooling.

Not exact matches

But in East Antarctica, where rising temperatures have caused increased humidity and thus more snowfall, the story takes an unexpected turn.

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.

After all, warmer air can hold more water, and some research suggests global warming could increase California's average rain and snowfall.

Local officials claim this is proof that the government's environmental preservation efforts have been successful, but recent research by climate scientists suggests a more worrying explanation for rising water levels: not only is climate change thought to be responsible for increased rainfall and snowfall in the area, it has also caused, by some estimates, up to a fifth of the permafrost which covers 80 % of the plateau to melt.

And by the way, if increased temperatures can make snowfall more likely that doesn't apply to these snowfalls which took place in record breaking cold.

Indeed, snowfall is often predicted to increase in many regions in response to anthropogenic climate change, since warmer air, all other things being equal, holds more moisture, and therefore, the potential for greater amounts of precipitation whatever form that precipitation takes.

The open Arctic is such a prolific producer of precipitation that the increased winter snowfall amounts to more than the oblique rays of the sun can melt away during the short northern summer.

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.

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.

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.

Proponents of human - caused global warming might claim that climate models predict increased snowfall in the Antarctic, because more warmth draws more moisture into the air that snows out.

Increased snowfall over the region is consistent with global climate models because a warmer atmosphere holds more moisture.

in addition another thought they do not bring up is under sea volcanic activity may heat up the oceans, increasing the amounts of water vapor put into the atmosphere which could result in more snowfall and eventual glaciation.

In particular, over NH land, an increase in the likelihood of very wet winters is projected over much of central and northern Europe due to the increase in intense precipitation during storm events, suggesting an increased chance of flooding over Europe and other mid-latitude regions due to more intense rainfall and snowfall events producing more runoff.

In some regions where winter precipitation is projected to increase, the increased snowfall can more than make up for the shorter snow season and yield increased snow accumulation.

«Ice sheets now appear to be contributing modestly to sea level rise because warming has increased mass loss from coastal areas more than warming has increased mass gain from enhanced snowfall in cold central regions,» the report by a team led by Professor Richard Alley of Pennsylvania State University in the US says.

-- 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.

Image right: Antarctica lost much more ice to the sea than it gained from snowfall, resulting in an increase in sea level.

That's doubly true when there is also emerging evidence — documented by Senior Weather Channel meteorologist Stu Ostro and others — that «global warming is increasing the atmosphere's thickness, leading to stronger and more persistent ridges of high pressure, which in turn are a key to temperature, rainfall, and snowfall extremes and topsy - turvy weather patterns like we've had in recent years.»

I get what you are pointing out, that this snowfall increase defies the predictions of the warmists [or now, in their latest claim that more warming means more snowfall....

Surprisingly, however, over the past two to three decades, the increase in extreme weather has included more (not fewer) severe cold - air outbreaks and heavy snowfalls observed both in North America and Eurasia6, 12,15,18,22,23,24,25.

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.
