A thunderstorm tends to be more severe and have a longer duration if the axis of the storm is: tilted, perpendicular to the ground, or it makes no difference.

In order to determine whether a thunderstorm tends to be more severe and have a longer duration based on the axis of the storm, we need to consider the atmospheric dynamics involved.
The axis of a thunderstorm typically refers to the orientation of the storm system. In this case, we are given three options to consider: tilted, perpendicular to the ground, or it makes no difference.
To understand the potential impact of these orientations, we can evaluate how each option relates to the vertical development of the storm.
1. Tilted axis: If the axis of the storm is tilted, it means that the storm system has a slanted structure. This tilting often occurs due to wind shear, which is a change in wind speed or direction with height. A tilted storm system can enhance the organization and strength of the thunderstorm because it promotes the separation of updrafts (rising air) and downdrafts (descending air). This separation allows for a sustained inflow of warm, moist air at the surface, which helps fuel the storm's intensity and longevity. Therefore, a storm with a tilted axis tends to be more severe and have a longer duration.
2. Perpendicular axis: If the axis of the storm is perpendicular to the ground, it means that the storm system is vertically aligned. In this case, there is less separation between the updrafts and downdrafts, and the storm's vertical development may be limited. Consequently, a thunderstorm with a perpendicular axis is less likely to be as severe or have a longer duration compared to a tilted storm.
3. It makes no difference: The assertion that the axis of the storm makes no difference is not supported by atmospheric science. The orientation of the storm system has a significant impact on its severity and duration, as explained above.
In summary, a thunderstorm tends to be more severe and have a longer duration if the axis of the storm is tilted. A perpendicular axis can limit the storm's vertical development, leading to less intensity and a shorter duration.
