Abstract

In the framework of the study, a comparative analysis of information on the cloud base height for the territory of Western Siberia based on the ERA5 reanalysis data and visual observations at weather stations is carried out for the period 2000- 2020. Spatial distribution maps were constructed, and a comparative analysis of spatial and temporal variability was carried out. The variability in cloud base height of vertical development clouds is also estimated. Spatial distribution of the total cloud base height values from observational data, in general, shows the similarity in all seasons: it increases from north to south of the region. However, we obtain contradictory results as for temporal variability. Thus, for further investigations, it is also necessary to use other types of databases and to take into account additional meteorological parameters to derived more accurate estimations of cloud base height values.
