“…The site was clear-felled in March-April 2016. After logging the large amount of harvest residuals, stumps and litter were remained on the ground (Mamkin et al 2016(Mamkin et al , 2019. During the first months after logging the site was free of any vegetation.…”

“…It is important to point out that the lowest values of LE were measured during the first year after the timber harvest. The previously conducted comparisons of the energy fluxes in undisturbed forest and at the clear-cut area (Mamkin et al 2019) showed that the clear-cutting led to decrease of LE by 30% in the first growing season following harvest. Moreover, the H also decreased due to the harvesting by 22%.…”

“…Most of previous experimental studies were performed at disturbed forest ecosystems in North America and Europe but effects of clear-cutting on ecosystem-atmosphere exchange in Russian boreal forests are still very poorly investigated and represented in a couple of experimental and modeling studies only (e.g. Machimura et al 2008;Mamkin et al 2016Mamkin et al , 2019Molchanov et al 2017). Boreal forests cover large areas in Russia and they are very sensitive to different natural and anthropogenic disturbances (zamolodchikov et al 2017).…”

Forest clearing strongly influences the energy, water and greenhouse gas exchange at the land surface-atmosphere interface. To estimate effects of clear cutting on sensible (H), latent heat (LE) and CO 2 fluxes the continuous eddy covariance measurements were provided at the recently clear-cut area situated in the western part of Russia from spring 2016 to the end of 2018. The possible effects of surrounding forest on the air flow disturbances and on the spatial pattern of horizontal advection terms within the selected clear-cut area were investigated using a process-based 3D momentum, energy and CO 2 exchange model. The modeling results showed a very low contribution of horizontal advection term into total turbulent momentum fluxes at flux tower location in case of the southern wind direction. The results of field flux measurements indicated a strong interand intra-annual variability of energy and CO 2 fluxes. The energy budget is characterized by higher daily and monthly LE fluxes throughout the entire period of measurements excepting the first two months after timber harvest. The mean Bowen ratio (β=H/LE) was 0.52 in 2016, 0.30-in 2017 and 0.35-in 2018. Analysis of CO 2 fluxes during the first year following harvest showed that the monthly CO 2 release at the clear-cut area consistently exceeded the CO2 uptake rates. The mean net ecosystem exchange (NEE) in the period was 3.3±1.3 gC•m-2 •d-1. During the second and the third years of the flux measurements the clear-cut was also a prevailed sink of CO 2 for the atmosphere excepting short periods in June and in the first part of July when daily CO 2 uptake was higher than CO 2 release rates. The mean NEE rates averaged for the entire warm period of corresponding years were 1.2±2.3 gС•m-2 •d-1 in 2017 and 2.8±2.5 gC•m-2 •d-1 in 2018, respectively. The mean ratio between gross primary production (GPP) and ecosystem respiration (TER) was 0.58

“…In turn, forests via the various feedback mechanisms (emission and absorption of CO 2 , albedo, evapotranspiration, precipitation interception) affect the local, regional, and, to some extent, global weather and climate conditions (Bonan et al 1992;Brovkin et al 2009;Bathiany et al 2010). Any forest disturbances can influence surface albedo, net radiation, sensible and latent heat, and CO 2 fluxes between the land surface and atmosphere, and can substantially affect climate conditions from local to global scales (Kulmala et al 2014;Seidl et al 2014;Mamkin et al 2019). These feedback mechanisms were investigated over the last decades in many experimental and modeling studies (Nobre et al 1991;Bonan et al 1992;Carlson and Groot 1997;Pielke et al 2007;Olchev et al 2009;Brovkin et al 2009;Anav et al 2010;Bathiany et al 2010;Kulmala et al 2014;Mamkin et al 2016Mamkin et al , 2019.…”

They showed a large diversity of feedbacks of forest and land use changes on local and regional weather conditions that could not be explained without deep understanding of all available relationships and effects arising between atmospheric and the land surface processes.…”

Forest vegetation can affect the climate and weather patterns in multiple ways. What are the main mechanisms of such influence and how the land-use and vegetation changes may affect the weather and climate conditions in different geographical regions are still not quite clear. In our study, the possible impact of land use and forest cover changes in the central part of the East European plain on regional meteorological conditions was investigated using the regional COSMO model. In our modeling experiments we used two extreme land-use change scenarios imitating total deforestation and afforestation of experimental area located between 55° and 59ºN and 28° and 37°E in the central part of the East European plain. Modeling results conducted for the year 2016 showed that deforestation results in increase of the temperature difference between summer and winter months by up to 0.6ºС and in reduction of the annual precipitation by 35 mm. On the contrary, afforestation leads to decrease of the annual temperature range by 0.3° С and to growth of annual precipitation by 15 mm. Moreover, the deforestation results in higher frequencies of stronger winds and lower number of fog events, while the afforestation leads to opposite effects. Analysis of the Khromov and Gorchinsky indexes of continentality showed that the deforestation of the selected experimental area may lead to increase of the climate continentality in the study region, whereas the afforestation results in milder climate conditions.
