Electrical aspects of rain generation is a research project funded by the UAE Research Program for Rain Enhancement Science (2nd cycle award).
It aims to fully evaluate the importance and significance of charge in influencing the size distribution of droplets in clouds, and with it the efficacy of artificially modifying the in-cloud rainfall generation which this relatively unexplored route potentially provides.
This project will investigate the electrical properties of clouds through a combination of theoretical and experimental work, firstly through modelling the growth of charged drops to raindrops and secondly by measuring and modifying the charges present in clouds using balloons and aircraft. An innovative aspect is that the internal electrical properties of the clouds will be investigated using Unmanned Aerial Vehicles (UAVs), adapted to deliver charge into the clouds. A promising attribute of the electrical seeding approach is that it leaves no local environmental residues, and can exploit pollution-free electrically powered robotic aircraft as the delivery platform.
