Measurement of the specific surface area of snow using infrared reflectance in an integrating sphere at 1310 and 1550 nm [PDF]
, 2009 International audienceEven though the specific surface area (SSA) and the snow area index (SAI) of snow are crucial variables to determine the chemical and climatic impact of the snow cover, few data are available on the subject.

Studying interspecific population synchrony: current status and future perspectives
Ecography, EarlyView.Interspecific population synchrony, or co‐fluctuations in the population dynamics and demographic parameters of different species, is an important ecological phenomenon with major implications for the stability of communities and ecosystems. It is also central in the context of biodiversity loss, as interspecific synchrony can influence how ecological ...

A stratification model of surface snow at Dome Fuji Station, Antarctica [PDF]
, 2002 A stratification model of surface snow on the ice sheet, which includes snow density evolution, is proposed. Using the temperature profile in the surface snow layer obtained at Dome Fuji Station, Antarctica, snow density evolution under various ...

Studies on the characteristics of snow particles affecting new snow density
Journal of the Japanese Society of Snow and Ice, 2005 二重防風ネット内で堆積した乾き新積雪の密度に対する平均気温および平均降水強度の影響に加えて,降雪粒子の卓越結晶形,水平粒度分布,霰寄与率(質量フラックスに占める霰の割合),雪面への運動エネルギーフラックスおよび粒子投映像の円形度との関係を解析した.その結果,新積雪密度への影響として,卓越結晶と平均降水強度の他に,雲粒付樹枝では運動エネルギーフラックスとの相関が大きかった.また,雲粒付立体樹枝では水平粒度分布,円形度,霰寄与率および運動エネルギーフラックスの影響も比較的顕著にみられた.さらに,卓越結晶形の霰(霰寄与率≧70%)では,水平粒度分布の影響が他の因子より大きかった.

Ecography, EarlyView.Anthropogenically induced changes in environmental conditions have been affecting species communities globally, leading to shifts in ecosystem functioning. Physical drivers like temperature, salinity and acidification are especially important in coastal ecosystems, and high‐resolution time‐series are essential to identify how these variables affect ...

Ecography, EarlyView.The spatial ecology of stalk‐and‐ambush predators like the Eurasian lynx Lynx lynx depends on prey availability and environmental features, yet the relative roles of these factors remain unclear at large spatial scales. In this study, we analysed lynx habitat use across central and southern Finland using snow‐track data from the Wildlife Triangle ...

Relationship between Snow and Temperature over Some Iraqi Meteorological Stations
Al-Mustansiriyah Journal of ScienceBackground: Snow forms when tiny ice crystals in clouds stick together to become snowflakes. If enough crystals stick together, they become heavy enough to fall to the ground.

Characteristics of the Snow Cover in East Antarctica along the Route of the JARE South Pole Traverse and Factors Controlling Such Characteristics [PDF]
, 1973 Glaciological studies of the upper 10m of the ice sheet in East Antarctica were made during the JARE South Pole Traverse 1968-1969. The glaciological studies consisted of studies of surface snow and subsurface snow by means of pits as well as analyses of

The Strength–Density Relationship for Dry Snow [PDF]
Journal of Glaciology, 1967 A linear relationship between strength and density is a characteristic feature of deposited snow. This relationship is explained theoretically in the case of old dry snow in ternis of the theory of sintering. The discontinuity in the relationship at a density of about 0.4 g./cm3 is considered to mark a transition point below which the snow densifies ...
