The"Boring Billion"refers the era between c.1.8 and 0.8 billion years ago(Ga)(Holland,2006;Young,2013).Especially,the period from 1.6 to 1.0 Ga is known as"the dullest time in Earth’s deep-time history"(Buick et al.,1995).The reason why this period is referred to as the"Boring Billion"is because there were very few’special’or’interesting’events discovered in the geological or geochemical records over nearly one-fourth of Earth's deep-time history. 展开更多

Record ozone loss was observed in the stratospheric Arctic in the spring of 2011. In the present work, we show observational evidence that the record loss of Arctic ozone is due to the extremely cold and persistent stratospheric polar vortex in the winter of 2010-2011. The polar vortex was as usual in early winter, but was intensified twice in middle January and middle February, respectively, and remained anomalously strong and stable until early April, 2011. Record low polar temperatures and record high subpolar zonal winds occurred in February and March. Stratospheric wave activity was anomalously weak because waves were refracted equatorward by the anomalously strong polar night jet. With such an extremely cold and isolated environment, Arctic stratospheric ozone was largely depleted in March and early April, 2011. Corresponding to Arctic ozone depletion, the stratospheric Northern-Hemisphere Annular Mode (NAM) displayed anomalously strong high-polarity, and the positive stratospheric NAM propagated downward and led to anomalously strong positive NAM in the troposphere and near the surface. 展开更多
