Sentences with phrase «snow surface»

How energy is transferred from the vegetation to underlying snow surfaces is understood in general terms but remains problematic in modelling and process details.

The air and snow surface temperatures warm when storm clouds pass over the site, acting as a blanket that traps heat, and then they gradually cool as heat radiates to space after skies clear.

«I like the monochromatic quality of winter in Sweden, when you have leaden grey backdrops and totally white snow surfaces of new fallen snow on the lake.

[Response: Particularly amusing nonsense, since Jim has been pointing out the importance of black carbon deposition (which replaces the normally highly reflective snow surface with highly absorbing particulates, thus enhancing surface warming) on Arctic warming for a number of years.

the importance of black carbon deposition (which replaces the normally highly reflective snow surface with highly absorbing particulates, thus enhancing surface warming) on Arctic warming for a number of years.

Recent extensive snowmaking upgrades allow the mountain to continue providing a quality snow surface throughout the ski season.

According to scientists, the dark skin is due to the higher level of ultraviolet rays that such people get, which is reflected from the ice and snow surface during the summer season, and the vitamin D that they obtain from eating fish and seal.

Often these white pellets (crystals) sit on ice and snow surfaces for a long period before penetrating.

No one should ever second - guess what a mountain reports for its conditions, weather, snow surface or anything else.

If a rain crust forms on the snow surface, this provides a slippery surface for new snow that might accumulate on top in subsequent snowstorms.

From here, I can prep the Rover for mud, sand, or snow surfaces, or I can leave it on «auto» which is a more reactive, but no less effective method.

The ACD unit employs an electronically controlled multi-plate clutch center differential, vectoring drive torque to the front and rear according to different driving conditions to realize the best balance between steering response and traction characteristics on Tarmac, Gravel, or Snow surfaces.

That means that any PFC from ski wax that is transferred to the snow surface will probably end up in soil and water sources.

Model simulations indicate that the snow - ice interface temperature or alternatively the 6 GHz brightness temperature is a closer proxy for the 50 GHz effective temperature than the snow surface or air temperature

SHEBA observations of the evolution of temperature over the course of winter within the atmosphere (red), at the snow surface (black), at the top of the sea ice (green), and at the ocean surface beneath the sea ice (blue).

Snow surfaces, on the other hand, have high reflectivity (40 — 80 percent) and so are the poorest absorbers.

The fact that AWS stations are likely to show a warming bias compared to manned stations (as the distance between the sensor and the snow surface tends to decrease over time, and Antarctica shows a strong temperature gradient between the nominal 3m sensor height and the snow surface) matters.

During snowmelt, about 50 % of the originally deposited soot particles were observed to remain at the snow surface.

The snow reflectivity, also known as albedo, of a natural snowpack was carefully measured after soot particles were deposited onto the snow surface.

Although the amount of UV radiation reaching the snow surface at Summit is notably influenced by stratospheric ozone levels, the UV measurement time series available in the Arctic is not yet long enough to allow trends to be detected.

Overall, doubling the dimming of the snow did not lead to twice as high temperature changes — it led to an approximate 50 percent increase in the snow surface temperature.
