A novel technique for subduing/modifying a tropical cyclone by artificially introducing liquefied or solidified gas/air near the sea surface in the region of an active tropical cyclone. Introduction of liquefied or solidified gas in significant amounts cools the warm moist air and increases the pressure due to enormous expansion of the said gas. This increase in pressure, in turn, reduces natural suction of air from the nearby regions. All these simultaneous phenomena will break the vicious cycle of the energy engine of a tropical cyclone and subdue it.
