Scenario studies of local atmospheric circulations in the Krasnoyarsk region

摘要

This paper presents a meso-scale non-hydrostatic model of atmospheric dynamics and some scenario calculations on formation of the local atmospheric circulations near the city of Krasnoyarsk. The results of numerical experiments are presented for summer and winter meteorological scenarios performed as a study of mesoclimates of the city and its surroundings. Using the numerical model it was possible to reproduce the processes of formation and development of the surface and elevated temperature inversions in the atmosphere of the territory in question. Experiments with basic state winds have shown that the orographic and thermal inhomogeneities of the underlying surface considerably transform the large-scale basic state flux.
