Feasibility study of artificial rainfall system using ion seeding with high voltage source

• Electric field intensity and velocity of ionized airflow are modelled and simulated.
• Mathematical model of feasibility of artificial rainfall is experimentally validated.
• Artificial intermediate ions with enough velocity are generated using high voltage.
• Number of ions and its velocity is proportional to input voltage (safe distance).
• Intermediate ions catalyses nucleation to electrify atmosphere and causes rainfall.

A non-linear computational modelling of ions from the ground station for electrifying the atmosphere to make feasibility study of artificial rainfall system is proposed and analyzed. The model considers generation of intermediate ions and ionized airflow velocity. The governing electro hydrodynamic (EHD) equations of the model shows that the space charge density, electric field intensity and velocity of the ionized airflow are function of high input voltage applied to generate the ions. The number of ions generated and their velocity is proportional to the applied ion generator voltage.These artificial ions will be introduced in the atmosphere which will act in a similar manner as cosmic rays. These ions will ionize the aerosols and catalyze nucleation processes and thus electrify the atmosphere which will form cloud droplets to get artificial rain. The mathematical model to study the feasibility of artificial rainfall is also validated under favourable conditions.
