• Question 10 of 10 10. Question 1 points Which of the following factors contribute to the formation of a bomb cyclone? Jet streams creating strong upper-level divergence A warm ocean surface providing heat and moisture The presence of a high-pressure ridge over the polar region An unstable atmosphere with strong vertical wind shear Select the correct answer code: a) 1, 3, and 4 only b) 2, 3, and 4 only c) 1, 2, and 4 only d) 1, 2, and 3 only Correct Solution: C A bomb cyclone is an intense mid-latitude storm that undergoes rapid intensification, defined by a pressure drop of at least 24 millibars in 24 hours. This process, known as bombogenesis, is driven by several key atmospheric and oceanic factors. Statement 1 (Correct): Jet streams play a crucial role in the formation of bomb cyclones. When a strong jet stream creates upper-level divergence, it allows air to rise rapidly, leading to low-pressure deepening at the surface. This accelerates storm development. Statement 2 (Correct): Warm Ocean surfaces provide heat and moisture, which act as fuel for the storm. This enhances cloud formation and intensifies the system, making it more powerful. Statement 3 (Incorrect): A high-pressure ridge over the polar region typically inhibits storm formation by suppressing cloud development and preventing deep low-pressure systems from strengthening. Statement 4 (Correct): Strong vertical wind shear (a significant change in wind speed or direction with height) increases atmospheric instability, promoting deep convection and the rapid intensification of the cyclone.
