We analyze the friction-velocity-normalized turbulence kinetic energy (
E
n
) in the near-ground atmospheric layer over urbanized territory. Based on the field measurements, we studied the dependence of
E
n
on the mean wind direction and the stratification type. Different
E
n
models are considered and compared with experimental data. It is found that the
E
n
models used do not provide the required simulation quality under the conditions encountered in field experiments. Hopefully,
E
n
will be adequately simulated taking into account not only the mean wind direction and the current stratification type but also some other wind flow characteristics.
