Abstract— A study of the radar characteristics of thunderclouds in India for the monsoon and post-monsoon seasons was carried out, separately for the cloud-to-ground and cloud-to-cloud discharges. It is shown that almost all the considered characteristics (cloud top height, precipitation flux and precipitation rate, maximum radar reflectivity, etc.) increase during the post-monsoon period. A feature of monsoon clouds is low electrical activity, which is confirmed by the results of the study. The characteristics of clouds during the transition to the thunderstorm stage are considered, the most significant of them are identified.
