Statistic characteristics of temperature inversions (frequency, duration, intensity, etc.) with high temporal and vertical resolution were extended based on the measurements by the temperature profilemer MTP-5 in Tomsk. The obtained data were compared with the investigations of thermal structure for the study territory. The characteristics of inversions in the atmosphere boundary layer were found to differ significantly from the characteristics recieved in earlier investigations.

In the paper, the possible use of a WRF mesoscale model for the detailed restoring of a temperature profile in the atmosphere boundary layer (ABL) during winter anticyclone is studied. The correctness of air temperature modeling as well as the possible use of a WRF model for predicting a vertical temperature distribution was shown.
Data on temperature inversions in the vicinity of Tomsk on the basis of MTP-5PE profiler data carried out at the IMCES SB RAS were summarized. It is shown that during persistent long-lived powerful anticyclones there is high recurrence of temperature inversions - they occur every day, or 90% of the time. A few characteristics of inversions observed in the region of the Bogashevo airport are presented.
