The subtropical and polar upper troposphere fronts and the polar vortex serve as the boundaries to divide the Northern Hemisphere into four meteorological regimes. These regimes are defined as (1) the...
The impact of anthropogenic chlorine emissions, stratospheric ozone change and chemical feedbacks on stratospheric water
anthropogenic chlorine emissions stratospheric ozone change chemical feedbacks
2009/2/25
Mixing ratios of water (H2O) in the stratosphere appear to increase due to increased input of H2O and methane from the troposphere and due to intensified oxidation of CH4 in the stratosphere, but many...
