Simulation of Feedbacks between Threated Activity, Atmosphere Composition, and Regional Climate

Abstract

The numerical model WRF-Chem was adapted and tested for the Black Sea region. WRF-Chem allows you to parameterize the concentration of NOx, and to analyze the contribution of lightning cells to the formation of ozone, the change in temperature fields. Model experiments for neutral stratification have shown that thunderstorm activity ambiguously affects ozone concentration and temperature. At the surface of the earth, the contribution of lightning discharges to the ozone concentration is minimal, and at an altitude of 10–12 km it increases significantly. The calculations demonstrate the importance of thunderstorm nitrogen oxides for the balance of ozone, associated gases, and also for the temperature distribution of the upper troposphere/ lower stratosphere.
