Study of contrail microphysics in the vortex phase with a Lagrangian particle tracking model
contrail microphysics a Lagrangian particle tracking model
2010/11/3
Crystal sublimation/loss is a dominant feature of the contrail evolution during the vortex phase and has a substantial impact on the later contrail-to-cirrus transition. Previous studies showed that t...
Influence of vortex dynamics and atmospheric turbulence on the early evolution of a contrail
vortex dynamics atmospheric turbulence the early evolution of a contrail
2010/8/12
This study describes three-dimensional numerical simulations of the evolution of an aircraft contrail during the first 30 min following the emission of exhausts. The wake is modeled as a vortex pair d...

Active chlorine species play a dominant role in the catalytic destruction of stratospheric ozone in the polar vortices during the late winter and early spring seasons. Recently, the correct understand...
Correlations of mesospheric winds with subtle motion of the Arctic polar vortex
mesospheric winds subtle motion Arctic polar vortex
2010/2/1
This paper investigates the relationship between high latitude upper mesospheric winds and the state of the stratospheric polar vortex in the absence of major sudden stratospheric warmings. A ground b...
Simultaneous measurements of OClO, NO2 and O3 in the Arctic polar vortex by the GOMOS instrument
OClO NO2 O3 Arctic polar GOMOS instrument
2009/11/9
We present the first nighttime measurements of OClO from a limb-viewing satellite instrument in the Arctic polar vortex. The relationship between OClO, NO2 and O3 slant column densities in the Arctic ...
