A bomb cyclone can cause severe winter weather. A bomb cyclone is a storm outside the tropics that has very low air pressure at its center. Bomb cyclones typically occur in the winter and can cause cold and stormy winter weather. Bombogenesis is the process of air pressure falling rapidly, which makes a storm into a bomb cyclone.
