THE POSSIBILITIES OF ANALYZING THE INVERSION LAYER ACCORDING TO REANALYSIS DATA

Abstract

The study of thermal inversion layers in the atmosphere plays an important role in understanding various atmospheric processes and solving environmental and meteorological problems. This work is devoted to evaluating the potential of thermal inversion layer analysis using ERA5 reanalysis data in the nearground layer as an alternative to the limited availability of aerological stations.The characteristics of inversions calculated using ERA5 reanalysis data and radiosonde data from the Karaganda Aerological Station for the period from 2012 to 2021 were compared. General inversions occur most often in January (15...18 times), while in spring and autumn, the average monthly number of cases is 4...10. In the summertime, surface inversions occur most frequently, with a mean monthly value of up to 25 times. The intensity of different surface inversions varies between -1 °C ... -9 °С. The results of the study showed a close similarity between the ERA5 reanalysis data and the radiosonde data. This indicates the suitability of the reanalysis data for studying thermal inversions. This study contributes to the development of knowledge in atmospheric pollution, weather forecasting, aviation meteorology, and the development of climate models by using reanalysis data to study inversion phenomena.
