A geoengineering approach toward tackling tropical cyclones over the Bay of Bengal

Abstract

The concept of seeding giant-sized ocean salt water aerosols in the eye-wall of a cyclonic storm abruptly increasing cloud condensation nuclei (CCN) concentration is investigated. To bring this to effect, design of a novel injection mechanism - a modified naval artillery shell, tailor made for the Indian Navy fleet, containing sea-salt solution to disperse the CCN is proposed. The effect of the seeding is modeled using a robust optimized warm rain microphysical scheme - amenable for quick local forecasts within the Weather Research and Forecast framework. The combined protocol results in a significant decrease in precipitation tendencies upon landfall.
