Consequences of the 2019 Greenland Ice Sheet Melt Episode on Albedo

Remote Sensing, 2021
In mid-June 2019, the Greenland ice sheet (GrIS) experienced an extreme early-season melt event. This, coupled with an earlier-than-average melt onset and low prior winter snowfall over western Greenland, led to a rapid decrease in surface albedo and ...

KINETICS OF GAS HYDRATES FORMATION AND GROWTH BASED ON MODIFIED ICE

Известия высших учебных заведений: Нефть и газ, 2017
The results of the studies of influence of polyvinylpyrrolidone on the kinetics of formation and the growth of Freon-12 gas hydrate are presented. Based on the P-V-T measurements the degree of conversion of ice into gas hydrate at various concentrations ...

Permafrost Mass Wasting in Ice‐Rich Landscapes: Recent Advances (2013 to 2024) on Mechanisms, Dynamics and Impacts

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Across circumpolar permafrost regions, climate change is destabilizing ice‐rich hillslopes, increasing the frequency and magnitude of thaw‐driven mass wasting. This paper reviews recent studies (2013–2024) on thaw‐driven mass wasting, focusing on the processes, morphology and trajectories of geomorphic change and their implications for ...

A Holistic Assessment of 1979–2016 Global Cryospheric Extent

Earth's Future, 2021
The cryosphere plays a major role in earth's climate system. Most cryospheric assessments focus on one or more of its components and their response to climate change.

Turbulent snow transport and accumulation: New reduced‐order models and diagnostics

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Our new reduced‐order models of snow particle transport provide high‐fidelity calculations of snow accumulation in turbulent flows at significantly reduced computational costs. Additional accumulation diagnostics from the reduced‐order model predict complex patterns of particle concentration in turbulent boundary layers via coherent flow structures in ...

Uncertainty assessment of a permanent long-range terrestrial laser scanning system for the quantification of snow dynamics on Hintereisferner (Austria)

Frontiers in Earth Science, 2023
A permanently installed terrestrial laser scanner (TLS) helps to investigate surface changes at high spatio-temporal resolution. Previous studies show that the annual and seasonal glacier volume, and subsequently the mass balance, can be measured by TLSs.

Recent Change—Terrestrial Cryosphere [PDF]

, 2015
This chapter compiles and assesses information on recent and current change within the terrestrial cryosphere of the Baltic Sea drainage basin. Findings are based on long-term observations. Snow cover extent (SCE), duration and amount have shown a widespread decrease although there is large interannual and regional variation.

The relationship between seasonal mean temperature and most extreme day

Quarterly Journal of the Royal Meteorological Society, EarlyView.
In Northern Hemisphere winter, there is a strong correlation between seasonal mean temperature and coldest daily mean temperature which varies in magnitude from one region to another (with a weaker relationship in summer between mean and hottest day).

Opportunities and threats of cryosphere change to the achievement of UN 2030 SDGs

Humanities & Social Sciences Communications
The cryosphere plays a critical role in maintaining the stability of the social-ecological system, but rapid cryosphere changes have been and are wide-ranging and have a profound affect, even threatening the achievement of the UN’s 2030 sustainable ...
