The northern Caspian region (Kalmykia, the Volga Delta, the Transcaspian lowlands, and northwestern Kazakhstan) is a year-round source of dust aerosol. Based on the data of Mosecomonitoring stations for 2011–2021 we analyzed the episodes of an increase in the level of aerosol pollution in Moscow near-surface air associated with long-range atmospheric transport of dust from the Caspian region. Eight months (about 6%) with the daily PM10 concentration in Moscow higher than MPC value during 3 or more days were revealed. The duration of each episode ranged from 3 to 10 days, and as a total they did not exceed 9% of days per year on average. During those episodes the maximal daily PM10 concentration in the near-surface Moscow air was 2.7 ± 1.1 times higher than the corresponding monthly values. The months with episodes of long-range atmospheric dust transport to Moscow are characterized by 1.9 ± 2.0°C higher air temperature and by 9 ± 13 mm lower precipitation amount relative to the corresponding norms for Moscow.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"37 5","pages":"620 - 629"},"PeriodicalIF":0.9,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S1024856024700842.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142859440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The results of long-term measurements of the atmospheric turbulence characteristics in the Sayan Solar Observatory (SSO) of the Institute of Solar-Terrestrial Physics, Siberian Branch, Russian Academy of Sciences, in summer 2023 are presented. It is confirmed that the cause of the prevailing direction of local winds appearing in SSO is the temperature mountain-valley gradient between the Sayan Mountains north of the SSO observatory and the valley to the south. A smaller level of the mean intensity of atmospheric turbulence in the SSO compared to the turbulence over a flat terrain in middle latitudes is confirmed. The presence of coherent turbulence in the SSO area is shown, at which the quality of images obtained by optical instruments is improved. New data are obtained for the turbulent scales of temperature and wind speed used in the Monin–Obukhov similarity theory depending on the atmospheric stratification. The results will be useful for specialists in astroclimate and theory of atmospheric turbulence.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"37 4","pages":"485 - 491"},"PeriodicalIF":0.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142714249","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Intermittence and random localization of CAT in a quiet surrounding air flow significantly restrict possibilities of its forecasting. Creation of systems for remote detection of turbulent zones becomes especially topical with allowance for climate changes and increase in the probability of CAT appearance. Results of turbulence sounding by the BSE-5 UV lidar from the Optik Tu-134 aircraft laboratory are presented. The in-flight experiment was conducted in September 2022 as part of the Arctic exploration program. The lidar recorded zones of moderate turbulence in the lower troposphere where the probability of turbulence is maximum; isolated cases of CAT were also recorded at an altitude of 9 km. The turbulent lidar can be used in practice for remote detection of turbulent zones at altitudes where most commercial flights are carried out. The prospects of ground-based application of the turbulent lidar for solving aviation safety problems during flights in the lower troposphere are also shown. The results of the BSE-5 lidar sounding in winter, when an increase in the intensity of turbulence in the 0.4–1.6-km layer was recorded during the passage of a cold front, are presented.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"37 4","pages":"492 - 501"},"PeriodicalIF":0.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142714340","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Employing a previously developed method for identifying RWB, adapted for stratospheric circulation, this study analyzes the climatology and long-term variability of RWB processes in the middle stratosphere. The method is based on the analysis of potential vorticity (PV) contour geometry at the 850-K level using ERA5 data within the PV range 0–400 PVU (Potential Vorticity Units) determined based on PV field climatology. It was demonstrated that RWB processes exhibit intraseasonal peculiarities. Most frequently, waves break in the northern regions of East Asia and the Pacific Ocean from October to December and in April to March. In January and February, no areas with prevailing RWB processes were identified. We obtained a statistically significant increase in the number of RWB for the first half of winter (October–December) and for the end of the winter period (March and April). For midwinter (January and February), insignificant negative trends were obtained. The results of this work can be used to analyze the long-term variations in stratospheric circulation and, in particular, the occurrence of stratospheric anomalies preceding sudden stratospheric warmings.","PeriodicalId":46751,"journal":{"name":"Atmospheric and Oceanic Optics","volume":"37 4","pages":"514 - 521"},"PeriodicalIF":0.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142714250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
