Hurricanes can weaken more quickly if it moves over cooler water, because they get their energy from warm tropical oceans.(n.d.) BC Air Quality.“Hurricanes derive their energy from the warm, tropical oceans and by evaporating water from the ocean’s surface.This traps the pollution into an area resulting in a poor air quality.Heat energy is converted to wind energy when the water vapor condenses and latent heat is released inside deep convective clouds” (Ahrens, 2014, p. 341).
