Sentences with phrase «more snowmelt»

«More snow means more snowmelt in [the] spring, resulting in larger melt ponds at that time,» which lowers the reflectivity of the sea ice, Feltham said.

Not exact matches

Due to deficiencies in the sewer collection system and lack of treatment capacity, wet weather events such as rain or snowmelt generate more wastewater than the plant can handle.

Birch trees not performing as expected That means a shorter period for snow to accumulate in winter and a bigger gap between snowmelt and summer rains, two factors that work together to produce more intense dry spells.

«As we reach a tipping point and see our customary water storage system, the snowpack, melting more and earlier in the winter, systems that rely on snowmelt will need to be reevaluated and modified.»

Wetter ground is more liable to flood when hit by a surge of rain or snowmelt.

These shifts may include rising sea levels, stronger tropical cyclones, the loss of soil moisture under higher temperatures, more intense precipitation and flooding, more frequent droughts, the melting of glaciers and the changing seasonality of snowmelt.

The UW researchers acknowledge that temperature is a very broad predictor of snowmelt behavior, yet they expect their theory to hold true as they look more closely at the relationship between climate and snowmelt throughout the Pacific Northwest.

Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.

These climate changes have measurable effects, like reductions in ground and surface water resources due to changing timing of precipitation and snowmelt, and measurable impacts like declining forest health and more wildfires, to altered crop seasons and greater irrigation demand.

Across Montana, conditions that lead to high fire risk (i.e., likelihood of occurrence) are becoming more common: seasonal maximum temperatures are increasing, snowmelt is occurring earlier, minimum relative humidities are decreasing, and fuels are becoming drier (Jolly et al. 2015; Seager et al. 2015).

Earlier snowmelt means no more slipping on ice or shoveling driveways, right?

The years with the earliest spring snowmelt, which was one - third of the total number of years we studied, account for more than 70 percent of the area burned in large forest wildfires, and 43 percent of the area burned in nonforest fires.

Global warming leads to more intense droughts, hotter weather, earlier snowmelt (hence less humid late summers and early autumns), and more tree infestations (like the pine beetle).

One more step: The unprecedented early snowmelt in the north is an extra source of heat, which helps enhance a high pressure ridge aloft.

The flooding is explained by higher than usual snowfall in late winter, followed by a late, but relatively quick onset of spring, with the flooding due more to snowmelt than rain.

Hotter and drier weather and earlier snowmelt mean that wildfires in the West start earlier in the spring, last later into the fall, and burn more acreage.

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 difficult.

More than one - sixth of the world's population live in glacier - or snowmelt - fed river basins and will be affected by the seasonal shift in streamflow, an increase in the ratio of winter to annual flows, and possibly the reduction in low flows caused by decreased glacier extent or snow water storage (high confidence)[3.4.1, 3.4.3].

The earlier snowmelt may benefit both species because there will be more berries, seeds, and bugs to eat early in the season when food can be scarce.

In particular, more winter and spring flooding and drier summers are expected as well as less winter snow (more rain) and earlier snowmelt.

In addition, climate change is very likely to lead to more frequent extreme heat events and daily precipitation extremes over most areas of North America, more frequent low snow years, and shifts towards earlier snowmelt runoff over much of the western US and Canada (high confidence).

Projected warming and drying in spring and summer combined with earlier snowmelt and more winter rain would likely exacerbate this trend by facilitating fire ignition and diminishing fuel moisture during the dry season [85].

The length of the growing season in interior Alaska has increased 45 % over the last century7 and that trend is projected to continue.8 This could improve conditions for agriculture where moisture is adequate, but will reduce water storage and increase the risks of more extensive wildfire and insect outbreaks across much of Alaska.9, 10 Changes in dates of snowmelt and freeze - up would influence seasonal migration of birds and other animals, increase the likelihood and rate of northerly range expansion of native and non-native species, alter the habitats of both ecologically important and endangered species, and affect ocean currents.11

Because of its cold - adapted features and rapid warming, climate change impacts on Alaska are already pronounced, including earlier spring snowmelt, reduced sea ice, widespread glacier retreat, warmer permafrost, drier landscapes, and more extensive insect outbreaks and wildfire, as described below.

Melting glaciers, early snowmelt, and severe droughts will cause more dramatic water shortages and increase the risk of wildfires in the American West.

Maybe I missed it, but it looks like to me that earlier snowmelt is associated with more wildfires, a reasonable connection.

For more than a century, Californians have relied on snowmelt - fed reservoirs, rivers and streams for much of our freshwater.
