Feedbacks between lightning activity, temperature and composition of the atmosphere

摘要

The prediction of lightning-generated nitrogen oxides in the troposphere and low stratosphere is evaluated using the Weather and Research Forecasting model coupled with Chemistry (WRF-Chem) with nested grid spacing of 15 and 5 km where convection is parameterized. The responses of nitrogen oxides, ozone, temperature and peroxyacetyl-nitrate (PAN) are investigated using matching of WRF-Chem sensitivity tests. A high-resolution simulation was performed for the Black sea region to examine feedbacks between atmospheric electricity and local weather. The result obtained shows that storms, occurring near the seaside, cause stronger effect on the land. Temperature fields show that continental difference is bigger than the coast one. The maximum temperature field difference is registered above 10 km altitude.
