Effects of highrise building on pollutant in the city centre at neutral stratification Isosurface of relative concentration C/C 0=0. 5‰ colored by temperature. Just slightly higher temperature is needed to cause a substantial change in the velocity of the slowspeed incoming wind Isosurface of turbulence kinetic energy, colored by streamwise vertical velocity W. It is clear that high-rise buildings and building arrays are dominant TKE production locations THMT 8, Sarajevo, B&H, September 15 -18, 2015 (A. Bevrnja, A. Žilić, S. Kenjereš, K. Hanjalić)
