Abstract

The layer-by-layer analysis of the variation dynamics of chemical parameters of snow at one of the observation sites (at the village of Yaksha) in the Pechora–Ilych state biosphere reserve in the winter of 2019–2020 has shown that the chemical composition of atmospheric precipitation is affected dominantly by long-range material transport. Features of the atmospheric circulation and the regions from which air masses are transferred control the saturation of the precipitation with certain chemical components. The calculation of the trajectories of reverse transport of air masses allowed us to identify regions where the air masses can be formed that come to the study area and carry material that potentially affects the chemical composition of the precipitation. The calculation of trajectories is demonstrated to make it possible to identify source regions of pollutants entering the atmosphere. This method of studying the chemical composition of snow is generally very informative and enables better understanding its formation factors.

大气环流对佩乔拉-伊利奇保护区积雪化学成分季节动态的影响

摘要：对佩乔拉-伊利奇国家生物圈保护区一个观测点（亚克沙村）2019-2020 年冬季雪的化学参数变化动态进行的逐层分析表明，大气降水的化学成分主要受远距离物质输送的影响。大气环流和气团输送区域的特征控制着降水中某些化学成分的饱和度。通过计算气团反向输送的轨迹，我们可以确定气团可能形成的区域，这些气团会来到研究区域并携带可能影响降水化学成分的物质。通过轨迹计算，我们可以确定污染物进入大气层的来源区域。这种研究雪的化学成分的方法通常信息量很大，可以更好地了解其形成因素。
