Lightning activity in Brazilian thunderstorms during TROCCINOX: implications for NOx production
During the TROCCINOX field experiment in January and February 2005, the contribution of lightninginduced nitrogen oxides (LNOx) from tropical and subtropical thunderstorms in Southern Brazil was investigated. Airborne trace gas measurements (NO, NOy, CO and O3) were performed up to 12.5 km with the German research aircraft Falcon. During anvil penetrations in selected tropical and subtropical t...
متن کاملAirborne quantification of upper tropospheric NOxproduction from lightning in deep convectivestorms over the United States Great Plains
The reported range for global production of nitrogen oxides (NOx=NO+NO2) by lightning remains large (e.g., 32 to 664mol NOx flash ), despite incorporating results from over 30 individual laboratory, theoretical, and field studies since the 1970s. Airborne and ground-based observations from the Deep Convective Clouds and Chemistry experiment in May and June 2012 provide a new data set for calcul...
متن کاملSevere convection and lightning in subtropical South America
Satellite radar and radiometer data show that subtropical South America has the world’s deepest convective storms, robust mesoscale convective systems, and very frequent large hail. We determine severe weather characteristics for the most intense precipitation features seen by satellite in this region. In summer, hail and lightning concentrate over the foothills of western Argentina. Lightning ...

Thunderstorms are one of the most important, abundant and severe atmospheric hazards. In addition to destroying a large amount of agricultural products and construction projects, cause many human casualties are annually in different parts of the world (Iran Pour and et al, 2015). This phenomenon is associated with severe storms, showery precipitation, hail (Puranik and Karekar, 2004), and thund...
متن کاملImpact of West African Monsoon convective transport and lightning NOx production upon the upper tropospheric composition: a multi-model study
Within the African Monsoon Multidisciplinary Analysis (AMMA), we investigate the impact of nitrogen oxides produced by lightning (LiNOx) and convective transport during the West African Monsoon (WAM) upon the composition of the upper troposphere (UT) in the tropics. For this purpose, we have performed simulations with 4 state-ofthe-art chemistry transport models involved within AMMA, namely MOC...
