REMOTE MEASUREMENTS OF SIMILARITY PARAMET ERS OF THE ATMOSPHERIC BOUNDARY-LAYER OVER A CITY

Surface heat flux, friction velocity, Oboukhov's scale, the height of zero heat flux, and the depth of the atmospheric boundary layer were e stimated from the data of sodar profile measurements of wind velocity, variance of the vertical wind velocity, and temperature structure par ameter under developed convection at the center of Moscow. The estimat es obtained show poor agreement with each other, which differs conside rably from the results of similar measurements taken over a uniform te rrain. This disagreement is apparently due to the invalidity of simila rity theory in modeling the structure of the atmospheric boundary laye r over a city.
