An Example of the Comparison of Middle Troposphere Instability Indices in the Prognostic Model with the Thunderstorm Activity Data

I. M. Gubenko and K. G. Rubinshtein

Presented is a review of thunderstorm forecast methods based on atmospheric instability in¬dices. Described are the main potential sources of thunderstorm observations. Obtained are the esti¬mates of the accuracy of the WWLLN global network that registers lightnings. Compared are the Meteosat-9 infrared images of convective clouds, the model maps of cloudiness, and some instability indices computed using the WRF-ARW model.
