Paper Abstract

Quantative parameters of urban environment impact on the thermal state of the atmospheric boundary layer are presented in the paper. Temperature profiles up to the height of 600 m were obtained in a continuous series of measurements by stationary and mobile microwave temperature profilers MTP-5 in Moscow (Russia) and in Nigny Novgorod (Russia). The influence of a large city on the parameters of the urban heat island (UHI) was estimated for the cases ofthe stationary atmospheric processes and for the frontal passage conditions. Two types of UHI were identified from the temperature profile measurements the warmer dome of urban heat at all levels and the low dome in combination with a lens of coal air above it. The time stability of the UHI illustrates sharp differences in the daily temperature change at different levels. The strongest UHI appears in the morning and at night. The accumulation of pollution and water in urban air accurse at this time and the UHI reaches maximum intensity. At the daytime UHI is broken down or remains only in the lower 300 meters. The temperature profiles data from the mobile profiler showed a big irregularity of UHI inside the city.
