The lack of aerosols below 30 km and the high dielectric strength of CO 2 at pressures equal to those near the surface of Venus imply that volcanism is not the source of lightning. | |
112 Citations | It is suggested that lightning at tropical and/or mid latitudes is the most likely source of Antarctic nitrate. |
Our experimental simulations indicate that volcanic lightning may be the only endogenous source of hydrogen cyanide (HCN) forming about 107 kg yr−1 of this compound. | |
8 Citations | Aerosols are shown to be regulators of lightning in regional studies, but their influence on lightning production at the global scale is not described. |
82 Citations | If lightning exists in the venusian atmosphere, it is either extremely rare, or very different from terrestrial lightning. |
The distributions are useful for understanding lightning characteristics as a function of storm evolution, specifying the vertical distribution of lightning-produced nitrogen oxides in chemical transport models and verifying model-simulated lightning. | |
Thus, understanding the effects of thunderstorms and lightning in the atmosphere is a must, and these effects must be used as inputs in any atmospheric model created to understand the effects of human-made greenhouse gases in the atmosphere. | |
16 Citations | Our results demonstrate that one important task is to raise the accuracy of estimates of the rate of nitrogen oxide production by lightning discharges and to use physical parametrizations that take into account the local lightning effects and feedbacks arising in this case rather than climatological data in models of the gas composition and general circulation of the atmosphere. |
This wide range of efficiencies across models is partly due to the assumed vertical distribution of the lightning source and partly to the treatment of nonmethane volatile organic compound (NMVOC) chemistry. |
