Effects of denitrification on the distributions of trace gas abundances in the polar regions: a comparison of WACCM with observations by M. Weimer, D. E. Kinnison, C. Wilka, S. Solomon

“…While the existence of large NAT particles (NAT “rocks”) has been verified by many measurements, especially in the Northern Hemisphere (NH), most current chemistry–climate models use simplified parameterizations, often based on evaluations in the Southern Hemisphere where the polar vortex is stable enough that accounting for NAT rocks is not as important as in the NH. …”

Mid-Holocene reinforcement of North Atlantic atmospheric circulation variability from a western Baltic lake sediment record by M. Czymzik, R. Tjallingii, B. Plessen, P. Feldens, M. Theuerkauf, M. Moros, M. J. Schwab, C. K. M. Nantke, S. Pinkerneil, A. Brauer, A. Brauer, H. W. Arz

“…A multi-millennial increase in productivity throughout the last <span class="inline-formula">∼</span> 9600 years is associated with progressively warmer winters in northwestern Europe, likely triggered by the coinciding increase in Northern Hemisphere winter insolation. Decadal to centennial periods of higher productivity in KKJ tend to correspond to warmer winters during a more positive North Atlantic Oscillation (NAO) polarity, as reconstructed for the last 8000 years. …”

The onset of neoglaciation in Iceland and the 4.2&thinsp;ka event by Á. Geirsdóttir, G. H. Miller, G. H. Miller, J. T. Andrews, D. J. Harning, D. J. Harning, L. S. Anderson, L. S. Anderson, C. Florian, D. J. Larsen, T. Thordarson

“…Statistical treatment of the high-resolution multi-proxy paleoclimate lake records shows that despite great variability in catchment characteristics, the sediment records document more or less synchronous abrupt, cold departures as opposed to the smoothly decreasing trend in Northern Hemisphere summer insolation. Although all lake records document a decline in summer temperature through the Holocene consistent with the regular decline in summer insolation, the onset of significant summer cooling occurs <span class="inline-formula">∼5</span>&thinsp;ka at high-elevation interior sites but is variably later at sites closer to the coast, suggesting that proximity to the sea may modulate the impact from decreasing summer insolation. …”

Change of stable snow cover destruction dates in Northern Eurasia, 1936–2008: impact of global warming and the role of large-scale atmospheric circulation by V. V. Popova, I. A. Polyakova

“…Variation of the stable snow cover destruction dates are examined in order to reveal spatial and temporal peculiarities during the observational period, as well as influence of recent global warming and macro-scale atmospheric circulation variation (in the terms of Northern Hemisphere Teleconnection patterns). The close spatial correlation between time-series of the snow cover destruction dates was revealed for the major part of the investigated territory, especially for the regions occupied by plains and low mountains. …”
