The Ministry of Earth Sciences’ ongoing Cloud Aerosol Interaction and Precipitation Enhancement Experiment (CAIPEEX) is proving to be a welcome method for mitigating extreme drought conditions. It will also pave the way for a new cloud seeding protocol that can be followed in keeping with Indian conditions in future.
Cloud seeding is a method of enabling inefficient clouds to bring rain, or enhance rainfall from a seedable cloud by introducing seeding material. The secondary effect of evaporation from falling precipitation improves the thermodynamic efficiency of the environment to form fresh convective clouds and more rain. This principle is used to enhance rainfall and reduce pollution. Two types of seeding—‘ground’, using generators and rockets, and, ‘aerial’ seeding using aircraft are possible. Based on the type of cloud to be seeded...
