AbstractThis study investigates the impact of sea ice and snow changes on surface air temperature (SAT) trends on the multidecadal time scale over the mid- and high-latitudes of Eurasia during boreal autumn, winter and spring based on a 30-member ensemble simulations of the Community Earth System Model (CESM). A dynamical adjustment method is used to remove the internal component of circulation-induced SAT trends. The leading mode of dynamically adjusted SAT trends is featured by same-sign anomalies extending from northern Europe to central Siberia and to the Russian Far East, respectively, during boreal spring and autumn, and confined to western Siberia during winter. The internally generated component of sea ice concentration trends over the Barents-Kara Seas contributes to the differences in the thermodynamic component of internal SAT trends across the ensemble over adjacent northern Siberia during all the three seasons. The sea ice effect is largest in autumn and smallest in winter. Eurasian snow changes contribute to the spread in dynamically adjusted SAT trends as well around the periphery of snow covered region by modulating surface heat flux changes. The snow effect is identified over northeast Europe-western Siberia in autumn, north of the Caspian Sea in winter, and over eastern Europe-northern Siberia in spring. The effects of sea ice and snow on the SAT trends are realized mainly by modulating upward shortwave and longwave radiation fluxes.

AbstractA collection of traditional and ‘old life’ stories recorded in the late 1940s is used to reconstruct the sociolinguistic situation of the Enets community in Northern Siberia from the 1850s until the 1930s. The Enets had regular contacts with a number of neighbouring indigenous peoples (Nganasans, Tundra Nenets, Selkups, Evenkis, Dolgans) and later with Russian newcomers. The oral histories often comment on language use, and as a result we can reconstruct not only the languages that the Enets people used in this period, but also the contexts in which they used them. The Enets community’s multilingualism was typically characterized by command of key neighbouring languages, with the occasional command of other more (geographically and socially) remote ones. With close neighbours, language choice seems to have had limited social load, while in cases of trade or agonistic contact, the choice of language in interethnic communication seems to have followed a principle of asymmetric convergence towards the language of the party with the greatest contextual social power. The analysis is founded on a database of dozens of communicative events mentioned in the oral stories (over 50 are analyzed). Ongoing fieldwork on the modern sociolinguistic situation suggests that until quite recently there was considerable stability in the sociolinguistic norms governing multilingual interaction among the Enets.
