“…Urban breeze circulation is another factor probably enhancing the ventilation of the city, while at the same time promoting the pollutants transfer from industrial areas, located in suburbs, to the city center. Thus, urban-induced processes should be essentially considered in air quality forecasts for urban areas, e.g., in COSMO-ART model [99], which is now used for this purpose for Moscow region [100,101]. It is also important to take them into consideration in high-resolution weather forecast for urban areas, biometeorological applications and in downscaling of climate change scenarios as shown in [7,102].…”

Megacity-Induced Mesoclimatic Effects in the Lower Atmosphere: A Modeling Study for Multiple Summers over Moscow, Russia

Urbanization leads to distinct meteorological features of urban environments, and one the best-known is the urban heat island (UHI) effect. For megacities, these features become mesoscale phenomena (scale ≥ 10 km) that are amplified by the tropospheric feedbacks, and have substantial implications on human well-being. For the first time, a three-dimensional statistical description of the megacity-induced meteorological effects extending towards the lower troposphere for summer is acquired on a quasi-climatological timescale (a decade) based on high-resolution (1 km) simulations for Moscow with the COSMO-CLM model with and without its urban canopy model TERRA_URB. Our results confirm the features from previous observational and modeling studies, including the UHI itself, the cooling effect above established by the cross-over effect, the urban dry/moist islands and the urban breeze circulation. Particularly, the UHI shows a strong diurnal variation in terms of intensity and vertical extent between daytime (≈0.5 K/≈1.5 km) and nighttime (>3 K/≈150 m). We have discovered a systematic veering in the downwind shift of the UHI spatial pattern established by the Coriolis effect, and an enhanced stable stratification of the rural surroundings established by the urban plumes further downwind. Finally, extending the analysis to multiple summers demonstrates a substantial increase in summer precipitation (up to +25%) over the city center and its leeward side. These urban-caused mesoclimatic effects need to be taken into account in weather and climate services, including the design of future megacities.

“…The possible effects of forest fires on surface roughness characteristics due to reduced forest LAI were ignored in the study. The modeling algorithm describing particulate matter (PM) emission into the atmosphere during the forest fires [64][65][66] was evaluated and showed good agreement with various atmospheric observations [54].…”

“…The important feature of COSMO-ART is also its ability for joint simulations of meteorological parameters and chemical transformations at each time step that allows consideration of aerosol feedback on radiation and meteorological conditions in the atmosphere. The COSMO-RuART configuration is adapted for daily operational weather predictions using external information about pollution emissions over Russia [54]. It is especially important in regions with high aerosol concentrations in the air and is useful in areas with strong atmospheric pollution from anthropogenic sources or wildfires [55][56][57].…”

“…All modeling experiments in our study were performed using the COSMO-Ru and COSMO-RuART model configurations of the COSMO 5.0 model with 40 vertical levels up to a height of 22 km and with horizontal grid spacing of 0.06 degrees (≈6.6 km) on the Cray XC40-LC supercomputing system located at the Main Computer Center of Roshydromet (Moscow, Russia). This model grid spacing is currently used by operational short-range numerical weather forecast system COSMO-Ru [53,54] and balances forecast accuracy with computing demand.…”

“…The last modeling experiment used parameter settings similar to the first forest fire scenario but was conducted with the activated ART module to account for all possible effects of forest fires on regional weather conditions, including changes of surface albedo, forest coverage, LAI, air chemistry, and atmospheric aerosol concentrations [54]. Thus, all combinations of direct and feedback links between forest fires and atmospheric characteristics observed at the time of the forest burning period were considered in the study.…”

Effect of Natural Forest Fires on Regional Weather Conditions in Siberia

et al. 2020

Effects of forest fires on regional weather conditions were analyzed for Central and Eastern Siberia after warm and dry weather conditions in summer 2019 using COSMO-Ru (COnsortium for Small-scale MOdeling; Ru—Russia) and COSMO-RuART (ART—Aerosols and Reactive Trace gases) model systems. Four series of numerical experiments were conducted (one control experiment and three forest fire experiments assuming total vegetation destruction within the burned areas) to evaluate possible effects of forest fires on surface albedo and vegetation properties as well as their influence on air chemistry and aerosol concentration in the atmosphere. The modeling results showed significant influence of forest fires on regional weather conditions that occurred over large areas situated even away from burnt regions. Decreased surface albedo and reduced latent heat fluxes due to fire-induced destruction of forest cover lead to higher near-surface air temperature and lower air humidity in both burned and surrounding unburned forest areas. On the other hand, reduced incoming solar radiation due to smoke from forest fire plumes decreased land surface temperatures and increased thermal atmospheric stability resulting in reduced regional precipitation.
