## Abstract

A navigable vessel for use in reducing the intensity of a tropical cyclone having an eye located over an ocean comprises a plurality of artificial snow-making devices aboard the vessel, at least one pump coupled to the devices and accessible to a body of water in which the vessel is floating for supplying the devices with water for making artificial snow, and a power source coupled to the devices to operate the devices in concert for producing a substantially uninterrupted supply of artificial snow. The artificial snow-making devices have discharge nozzles oriented to project the artificial snow away from the vessel onto or above the water adjacent the vessel.

## Claims

### Claim 1

A method of reducing the intensity of a tropical cyclone having an eye moving in a path over an ocean, said method comprising providing multiple navigable vessels each of which is equipped with artificial snow-making devices capable of producing streams of artificial snow, positioning each of said vessels in a unique location on said ocean directly beneath said eye and moving in said path therewith, operating said vessels so that each one maintains its unique location relative to said eye while moving with said eye in said path, and while maintaining said vessels in said respective unique locations continually producing said streams of artificial snow and directing said streams onto or above the ocean water directly beneath said eye.

### Claim 2

A method of suppressing the wind-induced heat exchange of a tropical cyclone that is moving over an ocean toward a landfall and has an eye moving over said ocean, said method comprising taking up and maintaining a station moving on the ocean surface in said eye, said station thereby moving toward said landfall in the same path and at the same speed as said cyclone, and continually while in said station producing a substantially uninterrupted stream of coolant in particulate form and directing said coolant onto or above said ocean surface.

### Claim 3 (depends on 2)

A method according to claim 2 in which said coolant is artificial snow.

### Claim 4

A method for reducing the wind force of a tropical cyclone that is moving over water in a discernible path, said method comprising operating in the vicinity of the eye of said cyclone a plurality of mechanisms each of which is operable to reduce the heat that is available to said cyclone, and operating said mechanisms substantially simultaneously and without interruption while moving said mechanisms substantially in said path.

### Claim 5 (depends on 4)

A method according to claim 4 wherein said mechanisms include a plurality of artificial snow making devices, said method comprises operating said devices simultaneously substantially continually and without interruption, and projecting the simultaneous outputs of said devices over said water substantially continually and without interruption during motion of said mechanisms over said water in said path.

### Claim 6

A method of suppressing the wind-induced heat exchange of a tropical cyclone that is moving in a discernible path over an ocean region, from which region moisture is rising, said method comprising providing at least one floating navigable vessel operable for moving over said ocean, and arming said vessel with multiple coolant making devices, said method further comprising controlling said devices to operate in concert and orienting said devices to project said coolant away from said vessel onto or above the surface of said ocean, and operating said vessel to move on said surface in said path while simultaneously controlling said devices to produce a substantially uninterrupted stream of said coolant.

### Claim 7 (depends on 6)

A method according to claim 6 employing artificial snow as coolant.
