Consider the following statements regarding Bomb Cyclones:

1.Bomb cyclones are more common in the Atlantic Ocean due to the larger water

surface area for strengthening low pressure.

2.The principal mechanism behind the formation of bomb cyclones is mainly due to intense baroclinic instability and tropospheric frontogenesis.

3.A storm system is classified as a bomb cyclone if its central low pressure drops at least 24 millibars within 24 hours.

4.In regions of baroclinic instability, isobars and isotherms are parallel to each other.

Explanation:

To analyze each statement regarding bomb cyclones:

1. First Statement: Bomb cyclones are common in both the Atlantic and Pacific Oceans because these regions have large temperature contrasts, which enhance storm development, not solely due to a large water surface area.

2. Second Statement: It is correct. Bomb cyclones form due to intense baroclinic instability, which occurs when there is a strong temperature gradient, and frontogenesis, the formation of weather fronts.

3. Third Statement: It is correct. A bomb cyclone is defined by a rapid pressure drop of at least 24 millibars within 24 hours.

4. Fourth Statement: It is incorrect. In regions of baroclinic instability, isobars and isotherms typically intersect, not run parallel, facilitating energy exchange and cyclone development.

- Correct Answer: Option: 2 (Only two statements are correct), as Statements 2 and 3 are true.
