METEOROLOGY – EVERE WEATHER & TORM CALCULATOR
Extra Tropical Bomb
A precise tool.
What is the Extra Tropical Bomb & How does it work?
An explosive cyclogenesis, commonly known as an extra-tropical bomb, is a rapid intensification of a mid-latitude cyclone. This phenomenon typically occurs when the central pressure of the storm drops at least 24 millibars in 24 hours.
The rate of deepening can be calculated using the formula:
Delta p = frac{p_0 – p_t}{t}
Delta p = rate of deepening (mb/h), p_0 = initial pressure (mb), p_t = final pressure (mb), t = time in hours
Understanding this rapid deepening is crucial for meteorologists to predict severe weather conditions and potential storms.

Frequently Asked Questions
What is an extra-tropical bomb?
An extra-tropical bomb is a rapid intensification of a mid-latitude cyclone where the central pressure drops at least 24 millibars in 24 hours.
How do I calculate the rate of deepening for an extra-tropical bomb?
Use the formula Ξp = (p0 – pt) / t, where Ξp is the rate of deepening in mb/h, p0 is the initial pressure in mb, pt is the final pressure in mb, and t is the time in hours.
What does a rapid drop in central pressure indicate?
A rapid drop in central pressure indicates that the storm is intensifying quickly, which can lead to stronger winds and potentially more severe weather conditions.
Why is it important to understand extra-tropical bombs?
Understanding extra-tropical bombs helps meteorologists predict and prepare for rapidly intensifying storms, which can have significant impacts on local weather patterns and safety.
Can this calculator be used for tropical cyclones as well?
No, this calculator is specifically designed for extra-tropical bombs. Tropical cyclones have different characteristics and require a different set of calculations.
What units should I use when inputting the pressure values?
You should use millibars (mb) for both the initial and final pressure values.
How often does an extra-tropical bomb typically occur?
Extra-tropical bombs can occur relatively frequently, especially in mid-latitude regions during certain times of the year, but they are less common than tropical cyclones.
