“…The spatiotemporal dynamics of thunderstorm activity is taken into account. Firstly, the probabilistic criterion considers the level of thunderstorm activity in the controlled forest area on the basis of the retrospective thunderstorm front forming within the specified territory [21]. Secondly, the criterion also takes into account a cloud-to-ground lightning discharge especially that occurs during the night and can lead to the secondary forest fires.…”

The present article describes a new concept of lightning-caused forest fire danger using a probabilistic criterion. The assessment of forest fire danger is made on the basis of the algorithm that classifies the forest territory by vegetation conditions. Lightning activity is processed by the MODIS spectroradiometer according to the World Wide Lightning Location Network data and remote sensing data for the Timiryazevskiy forestry in the Tomsk Region. The cluster analysis of the WWLLN and MOD06_L2 product data are used in the present paper.

Improving the identification accuracy of spatial distribution of hazardous convective phenomena has relevant meaning for territories are not covered by lightning detection systems. We perform comparison on set of instances of registered lightning discharges by a Boltek single-point lightning detector with spatial instability fields. To determine the areas of atmospheric instability over the southeast of Western Siberia, Total Totals and K-index have been used. Values for the indices were calculated from balloon sounding data and ERA5 reanalysis. The results demonstrate an acceptable spatial agreement between the fields with high instability indices according to ERA5 reanalysis data and actual positions of thunderstorm cells. A validation of ERA5 indices values with upper-air data showed that a smaller consistency error correspond to Total Totals index. Therefore, to predict the spatial position of convective clouds producing thunderstorms over the southeast of Western Siberia, it is promising to use Total Totals index, which is calculated using either aerological measurements or satellite remote sensing data.
