Praca omawia przyczyny spadku temperatury powietrza obserwowanego po roku 2000 na stacjach północnego krańca Półwyspu Antarktycznego oraz osłabienia tempa wzrostu temperatury na stacjach środkowej i południowej części Półwyspu. Analiza przyczyn zachodzących zmian temperatury powietrza wskazuje, że czynnikiem odpowiedzialnym za spadki temperatury jest silny spadek temperatury powierzchni morza (dalej SST – sea surface temperature) na wodach Oceanu Południowego rozpościerających się na NW od Półwyspu Antarktycznego. Zarówno zmiany SST, jak i zmienność południkowych, ujemnych (z sektora północnego) składowych wiatru geostroficznego, które objaśniają łącznie około 60% wariancji rocznej temperatury powietrza na stacjach omawianego obszaru, zachodzą pod wpływem czynników naturalnych.
The paper presents the results of research into the role of changes in SST and atmospheric circulation variability in the formation of annual air temperature at the station the South Shetland Islands and the western coast of the Antarctic Peninsula. Four stations have been chosen for the analysis: Bellingshausen, Esperanza, Faraday / Vernadsky and Rothera. In this region (Fig. 2) these stations have the longest and most complete series of temperature measurements. After an analysis, annual average values of SST anomalies of the sea area extending from the N and NW of the area in question (variable SSTA20; see Fig. 2) and the average annual values of zonal and meridional components of geostrophic wind at the level of 1000 hPa (four points marked in Fig. 2) have been chosen as factors influencing the temperature variations at these stations. Regression analysis showed that SST variability and variability of meridional components of geostrophic wind of the points 60°S, 60°W and 65°S, 70°W have a strong, statistically significant influence on the variability of annual air temperature at the analyzed stations . Variability of zonal components of geostrophic wind does not play a significant role in shaping the temperature variation. The variability of meridional component of geostrophic wind and SST anomalies explain a total of about 60% of the observed variance of annual air temperature at the studied stations throughout the observation period (Table 2). The cause of the collapse of the strong positive trend of temperature after 2000, which occurred at these stations, is the occurrence of a sharp fall in SST in the analyzed sea area (Fig. 5). As a result, the South Shetland Islands and northern edge of the Antarctic Peninsula after 2000 began to cool, and the positive trend at stations in central and southern part of the Antarctic Peninsula became much weaker (Fig. 1). The analysis shows that the variation of meridional components of geostrophic wind and SST variability controlling temperature changes at the stations of west coast of the Antarctic Peninsula are a sign of natural processes. They are directly (SST anomalies) or indirectly (meridional components of geostrophic wind) the result of oceanic processes. This observed variability in temperature in the north of the region and the western coast of the Antarctic Peninsula, including a strong positive trend observed in the years 1951-2000 and its subsequent collapse in the years 2000-2012, must be regarded as a manifestation of natural variability.
