摘要

摘要 本文介绍了对卡拉达格国家自然保护区背景环境监测站(BEMS)2012-2021 年克里米亚地区地面臭氧浓度变化的研究结果,并对 2016 至 2021 年的最近 6 年进行了更详细的分析。尽管监测站附近没有明显的人为污染源,但观测区域的地面臭氧空气污染水平明显偏高。研究了地面臭氧浓度与气象参数之间的关系,并确定了导致地面臭氧污染水平上升的特征风向。分析了年际变化,并确定了导致个别年份当地夏季地面臭氧浓度最低值的因素。利用 NOAA HYSPLIT 模型和 ERA5 再分析气象场,对该地区的大气环流模式进行了空间分析。评估了臭氧浓度超过世界卫生组织(WHO)建议的 8 小时平均允许浓度 100 μg/m3 的事件的重复发生情况,并确定了这些事件的可能原因。确定了长程飘移的机制及其对监测站地区臭氧状况的影响。经评估,2012 年至 2021 年期间地面臭氧浓度的年度趋势在统计学上并不显著。

Ground-Level Ozone Concentration Variability Analysis in the Karadag Nature Reserve

Ground-Level Ozone Concentration Variability Analysis in the Karadag Nature Reserve

Abstract

This paper presents the results of a study of ground-level ozone concentration variability in Crimea at the background environmental monitoring station (BEMS) of the Karadag State Nature Reserve for 2012–2021 with a more detailed analysis of the last 6 years from 2016 to 2021. A significantly high level of air pollution by ground-level ozone in the observation area was revealed, despite the absence of significant sources of anthropogenic pollution in the vicinity of the station. The relationship between the ground-level ozone concentration and meteorological parameters has been studied, and characteristic wind directions leading to increased levels of ground-level ozone pollution have been established. Intra-annual variations are analyzed, and factors causing a local summer minimum of ground-level ozone concentration in individual years are identified. Using the NOAA HYSPLIT model and ERA5 reanalysis meteorological fields, a spatial analysis of the atmospheric circulation pattern in the region has been carried out. The recurrence of episodes in which the permissible 8-h average ozone concentration level of 100 μg/m3, as recommended by World Health Organization (WHO), was exceeded has been assessed, and the possible causes of these episodes are identified. Mechanisms of long-range transport and their contribution to the ozone regime in the station area have been established. Annual trends in ground-level ozone concentration between 2012 and 2021 are assessed as statistically insignificant.

期刊介绍: Izvestiya, Atmospheric and Oceanic Physics is a journal that publishes original scientific research and review articles on vital issues in the physics of the Earth’s atmosphere and hydrosphere and climate theory. The journal presents results of recent studies of physical processes in the atmosphere and ocean that control climate, weather, and their changes. These studies have possible practical applications. The journal also gives room to the discussion of results obtained in theoretical and experimental studies in various fields of oceanic and atmospheric physics, such as the dynamics of gas and water media, interaction of the atmosphere with the ocean and land surfaces, turbulence theory, heat balance and radiation processes, remote sensing and optics of both media, natural and man-induced climate changes, and the state of the atmosphere and ocean. The journal publishes papers on research techniques used in both media, current scientific information on domestic and foreign events in the physics of the atmosphere and ocean.
