Impact des incendies de forêts russes d’août 2010 sur la qualité de l’air et les propriétés de l’atmosphère

Abstract : During mid-July to mid-August 2010, the western part of Russia was affected by a strong heatwave episode favourable to the development of numerous wildfires. When analysing the Russian meteorological situation, particularly the time series of temperature we became convinced that the huge PM concentrations were responsible for an attenuation of the maximum temperature in Moscow. The research performed with the LOA (Laboratoire d’Optique Atmosphérique) showed a strong impact of particulate matter concentrations on the meteorology with a reduction of the solar radiations close to the ground and then a stabilization of the atmosphere and lower temperatures. The feedback on meteorology increased the PM concentrations in the low troposphere.
