Abstract: Disclosed herein is a method and system for accelerated dissipation of a tropical cyclone and/or a hurricane specifically as it makes a landfall in order that its strength and access to further geography are significantly reduced in an irreversible manner. A storage tank and pipeline-based system for forcefully dispensing large amounts of cool dry air into the landfalling cyclone and/or hurricane system is the key embodiment proposed herein by which large scale dilution of the cyclone/hurricane fuel (vapor) is achieved. Other embodiments suggest augmenting this system with dry air drawn from adjoining arid or desert territories, and introduction of seeding materials or cloud condensation nuclei.
