Q2. Explain the phenomenon of bomb cyclones in the context of mid-latitude weather systems. Analyse the atmospheric and oceanic conditions responsible for bombogenesis. Discuss the range of hazards associated with such storms. (15 M)
Difficulty Level: Medium
Reference: IE
Why the question Recent extreme winter storms in mid-latitude regions have highlighted the role of atmospheric and oceanic processes in generating high-impact weather events, making it a core theme in physical geography and disaster awareness. Key Demand of the question The question requires explaining bomb cyclones as a mid-latitude phenomenon, analysing the specific atmospheric and oceanic conditions that cause bombogenesis, and discussing the major hazards associated with such rapidly intensifying storms. Structure of the Answer Introduction Briefly introduce bomb cyclones as rapidly intensifying extratropical storms that transform ordinary mid-latitude disturbances into extreme weather systems. Body Bomb cyclones in mid-latitude systems: Suggest their baroclinic nature and rapid pressure deepening within extratropical cyclones. Atmospheric and oceanic conditions: Indicate the role of temperature gradients, jet streams, pressure gradients and warm ocean currents. Hazards of bomb cyclones: Briefly outline destructive winds, blizzards, coastal flooding and transport disruption. Conclusion Emphasise the need for improved forecasting and preparedness as bomb cyclones pose growing risks to mid-latitude regions.
