Abstract

Two lidar stations of Institute of Atmospheric Optics, Siberian Branch, Russian Academy of Sciences, recorded pronounced aerosol layers in the stratosphere over Tomsk on February 5 and 6, 2025. The analysis of lidar and additional meteorological information showed the occurrence of a rather rare phenomenon for middle latitudes, i.e., polar stratospheric clouds, at that time. The constructed back trajectories of air masses at the altitudes of the formation of polar stratospheric clouds over Tomsk showed that abnormally cold air masses were brought from the polar regions of Norway and Greenland. The results can be useful for specialists in atmospheric physics, climatology, and environmental protection.

2025年2月托木斯克上空平流层极地平流层云的观测

俄罗斯科学院西伯利亚分院大气光学研究所的两个激光雷达站于2025年2月5日和6日在托木斯克上空的平流层记录了明显的气溶胶层。对激光雷达和其他气象资料的分析显示，当时中纬度地区出现了一种相当罕见的现象，即极地平流层云。在托木斯克上空极地平流层云形成高度的气团的反向轨迹显示，异常的冷空气团来自挪威和格陵兰的极地地区。研究结果对大气物理学、气候学和环境保护方面的专家很有用。

期刊介绍： Atmospheric and Oceanic Optics is an international peer reviewed journal that presents experimental and theoretical articles relevant to a wide range of problems of atmospheric and oceanic optics, ecology, and climate. The journal coverage includes: scattering and transfer of optical waves, spectroscopy of atmospheric gases, turbulent and nonlinear optical phenomena, adaptive optics, remote (ground-based, airborne, and spaceborne) sensing of the atmosphere and the surface, methods for solving of inverse problems, new equipment for optical investigations, development of computer programs and databases for optical studies. Thematic issues are devoted to the studies of atmospheric ozone, adaptive, nonlinear, and coherent optics, regional climate and environmental monitoring, and other subjects.
