【 摘 要 】

The difference between air temperatures in a city and the countryside - urban heat island intensity - depends primarily on the type and density of the buildings and energy consumption in municipal economy. There are many ways and methods for urban heat island intensity assessment: from empirical formulas to numerical simulation. One of the most useful numerical models for such purposes is COSMO-CLM. Various modifications of the COSMO model are now widely used in scientific research of mesoscale meteorological and climatic processes, as well as in weather forecast operational practice. The goal of this paper is to show the role of anthropogenic heat fluxes caused by urban energy consumption in Moscow's urban heat island in wintertime nights under various weather conditions. Numerical simulations are performed using the COSMO-CLM model and a scheme called TERRA-URB with and without anthropogenic heat fluxes. Meteorological characteristics of the Moscow agglomeration are calculated using computational capacity of the A.M. Obukhov Institute of Atmospheric Physics RAS.
