“…The northern parts and mountain regions of Fennoscandia belong mainly to the zone of discontinuous permafrost. In these areas, thawing permafrost can cause various hazards, such as less stable ground and slope failures that can threaten local community infrastructure and become an increasing cost factor in the maintenance and construction of mountain infrastructure [97][98][99]. There is also evidence that palsas, peat covered permafrost mounds containing segregation ice and surrounded by wet mires, are shrinking in northern Fennoscandia [100].…”

Abstract:We studied climate trends and the occurrence of rare and extreme temperature and precipitation events in northern Fennoscandia in 1914Fennoscandia in -2013. Weather data were derived from nine observation stations located in Finland, Norway, Sweden and Russia. The results showed that spring and autumn temperatures and to a lesser extent summer temperatures increased significantly in the study region, the observed changes being the greatest for daily minimum temperatures. The number of frost days declined both in spring and autumn. Rarely cold winter, spring, summer and autumn seasons had a low occurrence and rarely warm spring and autumn seasons a high occurrence during the last 20-year interval (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009)(2010)(2011)(2012)(2013), compared to the other 20-year intervals. That period was also characterized by a low number of days with extremely low temperature in all seasons (4%-9% of all extremely cold days) and a high number of April and October days with extremely high temperature (36%-42% of all extremely warm days). A tendency of exceptionally high daily precipitation sums to grow even higher towards the end of the study period was also observed. To summarize, the results indicate a shortening of the cold season in northern Fennoscandia. Furthermore, the results suggest significant declines in extremely cold climate events in all seasons and increases in extremely warm climate events particularly in spring and autumn seasons.

“…Recent advances in dendrimer synthesis have led to an entirely new class of complex, electronic materials. These materials owe their great technological potential to the ability to self-assemble into the nanometer-scale geometries that modern molecular electronics requires (8). Further advances promise mechanical actuators, chemical sensors, and anisotropic conductors.…”

“…This figure also compares the respective scales against the time-mean ice volume. Interestingly, for the reanalyses with ice data assimilation, an increase in mean ice thickness seems to 15 lead to an increase in time and length scales, as it is suggested by the points in the bottom-left quadrant defined by the gray dashed lines (Fig. 13).…”

Abstract. The ocean-sea ice reanalyses are one of the main sources of Arctic sea ice thickness data both in terms of spatial and temporal resolution, since observations are still sparse in time and space. In this work, we first aim at comparing how the sea ice thickness from an ensemble of fourteen reanalyses compares with different sources of observations, such as moored upward-looking sonars, submarines, airbornes, satellites and ice boreholes. Second, based on the same reanalyses, we intent to characterize the time (persistence) and length scales of sea ice thickness anomalies. We investigate whether data assimilation 5 of sea ice concentration by the reanalyses impacts the realism of sea ice thickness as well as its respective time and length scales. The results suggest that reanalyses with sea ice data assimilation do not necessarily perform better in terms of sea ice thickness compared with the reanalyses which do not assimilate sea ice concentration. However, data assimilation has a clear impact on the time and length scales: reanalyses built with sea ice data assimilation present shorter time and length scales. The mean time and length scales for reanalyses with data assimilation vary from 2.5-5.0 months and 337.0-732.5 km, respectively, 10 while reanalyses with no data assimilation are characterized by values from 4.9-7.8 months and 846.7-935.7 km, respectively.
