A one dimensional model study of the mechanism of halogen liberation and vertical transport in the polar troposphere
halogen liberation vertical transport polar troposphere
font style='font-size:12px;'>
2009/3/10
Sudden depletions of tropospheric ozone during spring were reported from the Arctic and also from Antarctic coastal sites. Field studies showed that those depletion events are caused by reactive halog...
A Possible Mechanism for Boundary Layer Mixing and Layer Formation in a Stratified Fluid
Possible Mechanism Layer Formation Boundary Layer Mixing Stratified Fluid
