Abstract

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.
