Current Technology Situation and Research Progress of Artificial Snowmaking

open access: yesZhileng xuebao, 2021
The principle of snowmaking is simple, however the process is complex and highly dependent on environmental conditions. In recent years, to achieve the goal of "300 million people on ice and snow" and to host the "2022 Beijing Winter Olympic Games" China

Post‐Processed CMIP6 Climate Projections for Hydro‐Environmental Risk Assessment in the Middle East and Central Asia

open access: yesInternational Journal of Climatology, EarlyView.
Estimating water resources is important for regional climate impact analysis and risk estimation. The Middle East and Central Asia have largely reached the limit of sustainably usable water across their river basins and ecosystems. Strategies designed to mitigate environmental risks require a reliable estimation of water availability trends.

Formation and evolution of melt holes on vine-shoots during the winter in Quebec

open access: yesOENO One, 2002
Vine cultivation in Quebec is confronted with the problem of an unfavorable climate specially because of winter frost. Over the last few years, artificial snow has been used, at the experimental level, as one of the protective methods implemented during ...

Effects of snow cover on urban light climate environment in the high latitudes of northeast China

open access: yesScientific Reports, 2023
Light climate environment (LCE) has a significant impact on human health, behavioral characteristics, and the safety of life and property due to the high albedo of snow on the ground cover type, which in turn affects the regional climate and socio ...

Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

Numerical computations of facetted pattern formation in snow crystal growth [PDF]

open access: yes, 2012
Facetted growth of snow crystals leads to a rich diversity of forms, and exhibits a remarkable sixfold symmetry. Snow crystal structures result from diffusion limited crystal growth in the presence of anisotropic surface energy and anisotropic attachment

The missing woodland story: Implications of 1700 years of stand‐scale change on ‘naturalness’ and managing remnant broadleaved woodlands

open access: yesPeople and Nature, EarlyView.
Abstract Longer‐term perspectives—equivalent to the lifespans of long‐lived trees—are required to fully inform perceptions of ‘naturalness’ used in woodland conservation and management. Stand‐scale dynamics of an old growth temperate woodland are reconstructed using palaeoecological data.

Drivers of human attitudes towards wolves Canis lupus in Kazakhstan

open access: yesPeople and Nature, EarlyView.
Abstract Kazakhstan is recognized as a key stronghold for the grey wolf (Canis lupus). Nonetheless, the wolf status and the dynamics of human‐wolf coexistence in the region remain poorly understood. This study aims to fill that gap by exploring current attitudes towards wolves in Kazakhstan and identify the underlying drivers of these attitudes.
