Ideas flow on Antarctic vortex
Article Abstract:
The Upper Atmosphere Research Satellite (UARS) investigation focussed on the controversy regarding the speed of a material, flowing through the stratospheric vortex, in relation to ozone destruction over the Antarctic, during polar winter. The argument centers on the theory that air is effectively contained on seasonal time scales within the vortex, horizontally by the polar night jet stream and vertically by weak vertical velocities.

Rapid degradation of atmospheric methyl bromide in soils
Article Abstract:
Bromine radicals released from methyl bromide (CH3Br) cause about 30% less depletion of stratospheric ozone than previously estimated, according to studies that show CH3Br is irreversibly reduced by soil bacteria. Research with different soil types at low mixing compositions revealed that the global annual soil intake of CH3Br is 42 plus or minus 32 Gg, which indicates the atmospheric lifetime of CH3Br to be 0.8 years.
