The Critical Reception of Beethoven’s Compositions by His German Contemporaries, volume 2

The volumes in The Critical Reception of Beethoven's Compositions by His German Contemporaries bring to light contemporary perceptions of Beethoven's music, including matters such as audience, setting, facilities, orchestra, instruments, and performers as well as the relationship of Beethoven's music to theoretical and critical ideas of the eighteenth and nineteenth centuries. These documents, most of which appear in English for the first time, have been compiled from German-language periodicals published between 1783 and 1830. They present a wide spectrum of insights into the perceptions that Beethoven's contemporaries had of his monumental music. This is the second in a projected four-volume series. It begins with Opus 55, the Eroica, and ends with Opus 72, Fidelio.

An Intercomparison of Regional Atmospheric Circulation and the Melt Season Loss of Arctic Snow Cover and Sea Ice Extent Across the Land-Ocean Boundary

This study is designed to compare the monthly continental snow cover and sea ice extent loss in the Arctic with regional atmospheric conditions including: mean sea level pressure, 925 hPa air temperature, and mean wind direction among others during the melt season (March-August) over the 29-year study period 1979-2007. Little research has gone into studying the concurrent variations in the annual loss of continental snow cover and sea ice extent across the land-ocean boundary, since these data are largely stored in incompatible formats. However, the analysis of these data, averaged spatially over three autonomous study regions located in Siberia, North America, and Western Russia, reveals a distinct difference in the response of snow and sea ice to the atmospheric forcing. On average, sea ice extent is lost earlier in the year, in May, than snow cover, in June, although Arctic sea ice is located farther north than continental snow in all three study regions. Once the loss of snow and ice extent begins, snow cover is completely removed sooner than sea ice extent, even though ice loss begins earlier in the melt season. Further, the analysis of the atmospheric conditions surrounding loss of snow and ice cover over the independent study regions indicates that conditions of cool temperatures with strong northeasterly winds in the later melt season months are effective at removing sea ice cover, likely through ice divergence, as are warmer temperatures via southerly winds directly forcing melt. The results of this study set the framework for further analysis of the direct influence of snow cover loss on later melt season sea ice extents and the predictability of snow and sea ice extent responses to modeled future climate conditions
