Radar Characteristics of Convective Clouds during Transition to the Cumulonimbus Stage in Different Regions of the World

Radar characteristics of convective clouds during their transition to the cumulonimbus stage are considered for three regions of the world (India, North Caucasus, and northwestern Russia). The cloud depth increases in all the regions; the cloud reflectivity and cloud volumes with high reflectivity increase in Russia; changes in the cloud reflectivity are weak in India.
