Application of the numerical model TSUNM3 to study the urban heat island and the intensity of precipitation over the Siberian city of Tomsk

Abstract

The relevance of the study is associated with the development and validation of the TSUNM3 model for numerical local weather prediction. The results of its application over a limited territory of the Siberian region are presented. A study of the characteristics of an urban "heat island" and the analysis of the reliability of forecasting precipitation have been carried out. The calculation results are compared with observations of the atmospheric boundary layer parameters obtained with meteorological instruments of the Joint Use Center "Atmosphere" at the Institute of Atmospheric Optics of the Siberian Branch of the Russian Academy of Sciences.
