Gdy SLP nad Morzem Barentsa spada tworzy si\u0119 tam uk\u0142ad niskiego ci\u015bnienia zwany Bruzd\u0105 Barentso-Karsk\u0105.

Powoduje to wzrost na tych obszarach cz\u0119sto\u015bci wyst\u0119powania bezfrontalnych pog\u00f3d antycyklonalnych. W okresach wzrostu SLP nad Morzem Barentsa, Bruzda Barentso-Karska zanika, zaznacza si\u0119 wzrost SLP nad obszarem po\u0142o\u017conym na N od 55-58\u00b0N, a na S od tej granicy SLP spada.

Powoduje to odpowiednie, przeciwne do opisanych wy\u017cej, zmiany w strukturze pog\u00f3d na N i S od 55-58\u00b0N. Zmianami SLP nad Morzem Barentsa steruj\u0105 zmiany zasob\u00f3w ciep\u0142a w wodach tego morza (np. Smedsrud i in. 2012, 2020).

Spadek SLP nad Morzem Barentsa, jaki nast\u0105pi\u0142 po roku 1988, jest zgodny w czasie ze zmian\u0105 epok makrocyrkulacyjnych nad Europ\u0105 (z epoki E na epok\u0119 W), kt\u00f3rych przyczyn\u0105 by\u0142a zmiana fazy NA THC z ujemnej na dodatni\u0105.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000\"><strong>S\u0142owa kluczowe:<\/strong> ci\u015bnienie atmosferyczne, cyrkulacja atmosferyczna, NAO, Morze Barentsa, Europa<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000\"><strong>Abstract<br \/>\n<\/strong>The low-pressure system in the subarctic zone of the North Atlantic, forming the northern arm of the NAO dipole, varies significantly over time. It is composed of three alternating centers \u2013 the Labrador Sea low, the Icelandic Low and the Barents Sea low. The individual low-pressure centers mentioned above occur in various configurations, the mutual arrangement of which strongly influences the values of the NAO indices. The aim of the presented research was to determine the impact of isolated SLP changes over the Barents Sea area on atmospheric circulation in the Atlantic-European circulation sector, regardless of SLP changes in the Icelandic Low. When the SLP drops over the Barents Sea, a low-pressure system called the Barents-Kara Trough forms there. In such periods, SLP decreases significantly over the eastern part of the N Atlantic and Europe in the zone located N of 55-58\u00b0N, and SLP increases SLP of this border. The maximum increase in SLP is then observed in the latitude zone of 45-50\u00b0N and over western and central Europe (10\u00b0W &#8211; 25\u00b0E). During such a period, the trajectories of low-pressure systems move to the zone between 58 and 70\u00b0N. The frequency of low-pressure weather, including frontal weather, is increasing in this zone (55-70\u00b0N). South of 55-58\u00b0N, SLP and the frequency of anticyclones increase. These are most often very strongly eastward ridges of the subtropical N Atlantic anticyclone (Azores High). This increases the frequency of frontal anticyclonic weather in these areas. During periods of SLP increase over the Barents Sea, the Barents-Kara Trough disappears, there is an increase in SLP over the area located N of 55-58\u00b0N, and SLP of this boundary decreases. The tracks of low-pressure systems move over Western and Central Europe at lower latitudes (45-55\u00b0N). This causes appropriate changes in the weather structure in the N and S regions from 55-58\u00b0N, opposite to those described above. Changes in SLP over the Barents Sea are controlled by changes in heat resources in the waters of this sea (e.g. Smedsrud et al. 2012, 2020). Heat resources in the waters of the Barents Sea are regulated by a decreased or increased inflow of warm Atlantic Waters (e.g. \u00c5rthun et al. 2012). As a result, all these changes, including the SLP over Europe, are driven, with lags, by NA THC (North Atlantic Thermohaline Circulation) variability. The simultaneous decrease in SLP over the Barents Sea and the decrease in SLP in the Icelandic Low causes an extensive one- or two-center low-pressure system with a WSW-ENE orientation to form in the subarctic and Arctic zone, forcing air advection from the west over NE Europe and Siberia. The decline in SLP over the Barents Sea after 1988 is consistent with the change in macrocirculation epochs over Europe (from epoch E to epoch W), which was caused by the change of the NA THC phase from negative to positive.<\/span><\/p>\n<p style=\"text-align: justify\"><span style=\"color: #000000\"><strong>Keywords<\/strong>: atmospheric pressure, atmospheric circulation, NAO, Barents Sea, Europe<\/span><\/p>\n<p>&nbsp;<\/p>\n<p><span style=\"color: #000000\">Article is licensed under <\/span><a href=\"http:\/\/creativecommons.org\/licenses\/by\/4.0\/?ref=chooser-v1\" target=\"_blank\" rel=\"license noopener noreferrer\"><strong><span style=\"color: #0000ff\">CC BY 4.0<\/span><\/strong><img decoding=\"async\" style=\"height: 22px!important;margin-left: 3px;vertical-align: text-bottom\" src=\"https:\/\/mirrors.creativecommons.org\/presskit\/icons\/cc.svg?ref=chooser-v1\" \/><img decoding=\"async\" style=\"height: 22px!important;margin-left: 3px;vertical-align: text-bottom\" src=\"https:\/\/mirrors.creativecommons.org\/presskit\/icons\/by.svg?ref=chooser-v1\" \/><\/a><\/p>\n<p><a href=\"http:\/\/creativecommons.org\/licenses\/by\/4.0\/\" rel=\"license\"><img decoding=\"async\" style=\"border-width: 0\" src=\"https:\/\/i.creativecommons.org\/l\/by\/4.0\/88x31.png\" alt=\"Licencja Creative Commons\" \/><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>ZMIANY CI\u015aNIENIA ATMOSFERYCZNEGO NAD MORZEM BARENTSA I ICH WP\u0141YW NA CYRKULACJ\u0118 ATMOSFERYCZN\u0104 W ATLANTYCKO-EUROPEJSKIM SEKTORZE CYRKULACYJNYM Changes in atmospheric pressure over the Barents Sea and their impact on atmospheric circulation in the Atlantic-European circulation sector Andrzej A.
