Paper Abstract

It is shown that in the Siberian region the most intense fires are associated with atmospheric blocking (blocks), as well as the processes of Rossby waves breaking (RWB). Blocks and RWB in Siberia and Russian Far East in summertime both cause high temperatures, low humidity, and the decrease of clouds. Methane emissions from wildfires in Western Siberia during periods of atmospheric blocking are studied based on the Global Fire Assimilation System (GFAS) and the Global Fire Emissions Database (GFED). Both datasets have shown a sharp increase in methane emissions during or a few days after blocks. Methane emissions associated with blocks are higher according to GFAS data, compared to GFED. Even though for both datasets, there are problems with the correction of cloudiness, for GFAS, the problem of identification and correction of hot spot associated with gas flaring is probably more significant.
