Lightning, Air Quality, and Climate
Session ID#: 159792
Session Description:
Lightning plays an important role in reshaping air quality and also serves as an essential climate variable. For example, lightning itself is a producer of NOx and could start forest fires, directly influencing the air quality in its vicinity. Conversely, enhanced air pollutants such as climate forcers and aerosols from fires or anthropogenic sources could perturb Earth's energy balance, and have been linked to increased convective activity thus enhancing lightning under a changing climate. Interpreting the intricate relationships in-between lightning, air quality, and climate is critical to addressing air pollution concerns and mitigating climate change. The goal of this session is to solicit recent measurements and/or computational modeling studies that advance our understanding of the impacts of lightning on air quality and climate, as well as the feedback of changes in air pollutants and meteorological factors on convective activity and lightning density across local- to global- scales and in the short- to long- terms.
