abstract = {An idealized vertical-meridional zonally symmetrical
version of the Meso-NH model is used to study the response
of tropospheric ozone to the dynamics of the West African
monsoon, as well as surface emissions and NOx-production by
lightning (LNOx). An O-3-NOx-VOC chemical scheme has been
added to the dynamical model, including surface emissions
and a parameterization of the LNOx production. The model
shows that the ozone precursors emitted at the surface are
uplifted by deep convection and then advected in the upper
branches of the Hadley cells on both sides of the Inter
Tropical Convergence Zone (ITCZ). The NOx produced by
lightning promotes chemical ozone production in the middle
and upper troposphere from the oxidation of CO and VOCs. The
analysis of the convective and chemical tendencies shows
that the ozone minimum at the ITCZ is induced by venting of
ozone-poor air masses into the upper troposphere. The
bi-dimensional model suffers from limitations due to the
absence of exchange with the higher latitudes and
ventilation in the zonal direction. Despite of these
restrictions, sensitivity simulations show that the LNOx
source and biogenic VOCs are necessary to create the
meridional gradient of ozone observed by the Measurements of
OZone and water vapor by in-service AIrbus airCraft (MOZAIC)
aircrafts in the southern Hadley cell. The LNOx source is
also required to maintain the meridional ozone gradient up
to 24 degrees N in the northern Hadley cell. The modeled
meridional gradient of O-3 in the upper troposphere ranges
from 0.22 to 0.52 ppbv/deg without the LNOx source and from
0.60 to 1.08 ppbv/deg with the LNOx source, in the southern
and the northern cells respectively.},
