In a commentary paper, Bamber et al. (Nat Clim Change 3:424–427, 2016) respond to our recent assessment (De Vries and Van de Wal Clim Change 1–14, 2015) of their expert judgment based study on projections of future sea level rise due to the melting of the large ice sheets (Bamber and Aspinall Nat Clim Chang 3:424–427, 2013). In this response we comment on their remarks. 相似文献

Abstract The physical mechanism that causes an interdecadal oscillation in a coarse resolution sector ocean model forced by mixed boundary conditions is studied. The oscillation is characterized by large fluctuations in convective activity and air/sea heat exchange on a decadal timescale. Changes in the subsurface temperature and surface salinity are essential for the existence of the oscillation. It is shown that a large part of these variations can be explained with the hypothesis of a constant ocean velocity field. This may easily lead to the erroneous conclusion that the oscillation is mainly a “nondynamical” phenomenon. In this paper it is demonstrated that the ocean dynamics play an essential role in explaining decadal oscillations. 相似文献

Two British scientists, G.C. Simpson and C.T.R. Wilson, held contrasting views on the electrical polarity of thunderclouds for nearly half of the 20th century. Simpson's perspective was dominated by the measured charge on rain, by the breaking drop theory for the charging of raindrops, and later, by the branching behavior of lightning flashes. Wilson's view was dominated by his work on the field changes accompanying lightning, by his knowledge of the corona current from the ground beneath electrified clouds, and ultimately by his unifying global circuit hypothesis, requiring a source current to maintain a negatively charged Earth against dissipation. Simpson's observed tripole structure of thunderclouds provided partial resolution to the controversy, but the main positive dipole supported Wilson's view, which survives today. 相似文献
