Explanation:

Bomb Cyclone or bombogenesis refer to a rapidly intensifying area of low-pressure winter storm when there is a pressure drop by at least 24 millibars in 24 hours. Bomb Cyclone is caused by a collision of warm air and cold air which develop into rotating storm-like pattern and lead to an explosive deepening of pressure. Worldwide about 40 to 50 ‘bomb cyclones brew each year.
