Samokhina","doi":"10.1134/s0001433823140062","DOIUrl":"https://doi.org/10.1134/s0001433823140062","url":null,"abstract":"<h3 data-test=\"abstract-sub-heading\">Abstract</h3><p>Fluctuations in the frequency of cyclones in various regions of the Northern Hemisphere (NH) temperate latitudes on time scales of the order of decades are analyzed in connection with changes in the indices of the leading modes of atmospheric circulation and changes in the zonal transport intensity in individual latitudinal zones. The possible manifestation in cyclone statistics of the well-known thesis about the displacement of storm tracks during warming in the direction of high latitudes is discussed. It is shown that, in general, for the NH temperate latitudes in winter, long-period changes in the frequency of cyclones are irregular fluctuations with scales of several decades, without a visible trend. In summer, the interdecade changes are weakly expressed, but there is a noticeable trend that is significant at the 5% level. In the northern and southern parts of the North Atlantic (NA) in winter, changes in frequency contain significant antiphase components with a period of about 10 years, which correlate well with changes in the North Atlantic Oscillation (NAO) index (the correlation is positive in the northern half; the coefficients are significant at the 0.1% level). Long-period changes in the frequency of cyclones in the North Pacific are generally similar to (but in the opposite phase of) changes in the North Pacific Index by Trenberth and Hurrell. Based on the analysis of a linear regression model, it was found that a significant contribution to changes in the frequency of cyclones in the regions of northern Europe–Western Siberia and the north of ER (ER) in the winter season was made by the circulation modes of the Atlantic–European sector: SCAND, NAO, East Atlantic mode EAM, EAWR (but the EAWR mode contribution is insignificant for the north of Europe–Western Siberia). In summer, for the north of ER and Western Siberia, a significant contribution was made by the SCAND and EAWR circulation modes. An analysis of concomitant changes in zonal wind speed at 700 hPa in the area of the main storm tracks in winter revealed that, for the hemisphere as a whole (0°–360°) in the latitude zone 45°–55° N, as well as in the zone 55°–65° N, changes in zonal wind are determined mainly by changes in the frequency of cyclones in the northern part of the NA and closely follow changes in the NAO. However, in more southern latitudes (35°–45° N), changes in the hemispheric zonal wind are observed, similar to long-period changes in the North Pacific Index in antiphase, the nature of which is unclear (since they do not appear in the Pacific sector itself). The shift of storm tracks to higher latitudes, expected with warming, is observed only for the northern branch of the Atlantic storm track during periods of NAO growth between 1960 and the mid-1990s and after 2010. In general, for the period since 1976, there has been an insignificant trend of about 0.07° latitude per decade.</p>","PeriodicalId":54911,"journal":{"name":"Izvestiya Atmospheric and Oceanic Physics","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138556019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objectives are to develop software for analyzing the Lagrangian transport of air particles; assessing the deposition of aerosol particles by precipitation and the concentration of particles in the atmosphere; and obtaining, for specific conditions of atmospheric circulation during severe fires in the years of maximum reduction in the Arctic sea ice area, estimates of the relative residence time of air particles emitted by these fires over the Arctic Basin (AB), as well as the proportion of BC deposited in the AB from fires. This software package contains a module for calculating Lagrangian trajectories from a 4-dimensional wind array (<i>u</i>, <i>v</i>, ω, <i>t</i>), which contains horizontal wind components and an analog of vertical speed available from reanalysis, as well as modules for the postprocessing of the found trajectories, which allow us to obtain in a given area the residence time estimates, 3-dimensional BC concentration, and BC deposition on the surface, also using reanalysis data and some empirical constants. Since the main decrease in the Arctic sea ice area occurred in 2 years, 2007 and 2012, it was supposed to analyze the fires of these years; however, in 2007, there were no great fires, and in 2012 one fire was much larger than the others (K-217, March–June). This fire was chosen for the experiments: several sets of trajectories were obtained for it, corresponding to various options for choosing the initial conditions, and estimates were obtained for the fraction of trajectories that passed over the Arctic basin, the time spent there, and the fraction of BC deposited in the AB. Together, these estimates led to the conclusion that Siberian fires can hardly be the leading cause of the accelerated melting of Arctic sea ice.</p>","PeriodicalId":54911,"journal":{"name":"Izvestiya Atmospheric and Oceanic Physics","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138556184","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Atmospheric circulation, which transports heat, moisture and precipitation, also affects climatic conditions in the catchment areas of the three main Siberian rivers—the Ob, Yenisei, and Lena—the flow of which is approximately half of the annual average inflow of river water into the Arctic Ocean. According to reanalyses and archival data for 1979–2019, air temperature and precipitation in the Ob, Lena, and Yenisei catchment areas are increasing. The greatest increase in precipitation is recorded in the spring months. There is also a maximum positive trend in air temperature in the spring months (March and April). To assess the impact of low latitudes on changes in climatic conditions in the catchment areas, data from ERA5, HadISST reanalyses, and the GPCC project precipitation gridded gauge-analysis data are used. Based on the average monthly surface air temperature at the nodes of the geographic grid in the Northern Hemisphere, the indices of zonal, meridional, and general circulation are calculated. To determine the relationships between indices and climatic parameters, the methods of multivariate cross-correlation analysis are used. It has been found that zonal atmospheric transfers have a significant impact on climatic conditions most of all in the cold part of the year, especially in November and March. In summer, the increase in zonal circulation is accompanied by a decrease in air temperature in the catchment areas, and meridional transfers increase the temperature. The greatest influence of the meridional transport is noted in spring and summer. Climate changes at low latitudes have the greatest effect in autumn on meridional transport in the spring season and on zonal transport in the cold part of the year, especially in March, with a delay of 2 years.

Possible causes of the Arctic amplification have been considered and continue to be discussed in many articles and reviews. In this article, for the first time, a quantitative assessment of the role of atmospheric transports in the formation of variability and trends in the mean near-surface air temperature (SAT) in the Arctic and at adjacent latitudes of the Northern Hemisphere is carried out and an analytical description of amplification in high latitudes is proposed. For the study, data from NCEP and ERA5 reanalyses for 1989–2020 and a representation of the set of events of air exchange between latitudes in a simple hemispheric atmospheric model under constant conditions at the boundaries, on the basis of which analytical expressions are obtained for the standard deviation ratios (SDRs) and temperature trends in neighboring areas. The degree of closeness between the empirical and model ratios of SDR and trends is taken as a contribution measure of air exchange to the increase in SDR and trends during warming. It has been found that the exchange between the polar and adjacent regions reaches lower latitudes as the polar region expands from 70° N up to 60° N. The latitude to which the polar air propagates on average decreases with the trend taken into account in the SDR, which confirms the effect of warming on the increase in air mass exchange. The model value of the increase in the average air temperature trend in the polar region of an isolated homogeneous atmosphere above the hemisphere relative to the trend in the adjacent region is determined by the ratio of their areas multiplied by the ratio of the trend determination coefficients. An increase in the temperature trend in the polar region of the real atmosphere, according to the NCEP and ERA5 reanalyses for 1989–2020, was compared with the model value, thereby assessing the contribution of air mass exchange to the increase in the temperature trend in the polar region. It was found that the exchange explains 54% of the increase in the air temperature trend (Arctic amplification) in the region of 90–60° N on average per year and 66% in the cold year part relative to the rest of the Northern Hemisphere. If we take into account the established southern boundary of air mass exchange between the polar and adjacent regions, then the amplification of an air temperature trend in the area of 90–60° N relative to the trend in the adjacent area, with which the exchange of air masses occurs, will almost completely (by 93% on average per year) be the result of exchange and, in the area of 90°–70° N, it will mostly be the result of exchange (by 74% on average per year).</p>","PeriodicalId":54911,"journal":{"name":"Izvestiya Atmospheric and Oceanic Physics","volume":null,"pages":null},"PeriodicalIF":0.7,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138556679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"地球科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For winter and summer, changes in mean seasonal precipitation, the number of days with precipitation, and the frequency of extreme precipitation are analyzed. For the modern period 1991–2020, according to empirical data, in winter on the territory of Russia, a significant increase in seasonal precipitation amounts and the frequency of days with extreme precipitation on the Far East coast and in the central part of European Russia (ER) are detected. A decrease in the frequency of days with precipitation at most meteorological stations in Russia by 4–6 days/10 years is also noted. In summer, an increase in precipitation amounts and the frequency of days with precipitation is found in Western Siberia and on the coasts of the Sea of Okhotsk and the Pacific Ocean. A decrease in the amount and frequency of precipitation is obtained for southern ER and the south of Eastern Siberia. Climate models, on average for the ensemble, show an increase in the relative amounts of precipitation and the extreme precipitation frequency over most of the Russia territory in winter, and these trends may intensify in the coming decades. In summer, on the contrary, for southern ER, as a whole, there is a slight decrease in the seasonal precipitation totals and the number of days with precipitation.

The largest number of waves is observed in winter in the south of ER and in summer in the north. The contribution to the total seasonal duration of the longest waves (more than 12 days) is observed in winter in the north (&gt;40%); in summer, waves of such duration are not observed in the center and south of ER. Winter cold waves in all zones are characterized by areas of negative temperature anomaly, covering almost the entire territory of Russia, with centers in the corresponding zone of the ER and extending eastward up to 140° E. Summer waves have a three-field structure with centers of cold over ER and the west of Western Siberia and over Yakutia, and a positive anomaly in the eastern part of Western Siberia and western Central Siberia. Circulation structures in the troposphere accompanying the cold waves and their role in the formation of temperature anomalies are discussed. In winter, the H500 geopotential fields during waves in the center and south of ER are characterized by a powerful ridge over the north of ER and the Scandinavian Peninsula (which corresponds to the Scandinavian atmospheric circulation mode) and a trough in the south of ER and Western Siberia. Cold waves in the northern zone occur with a crest in the Atlantic north and a trough in the south (the North Atlantic Oscillation (NAO) negative phase) and a trough in the north of ER. Summer cold waves in all zones are accompanied by a cutoff cyclone centered in the corresponding zone (slightly to the north for waves in ER south); a negative geopotential anomaly over ER corresponds to the negative phase of East Atlantic–West Russia (EAWR) mode.
