Which statement is accurate regarding turbulence associated with thunderstorms?

The accurate statement regarding turbulence associated with thunderstorms acknowledges the influence of severe storms on surrounding air conditions. The idea that shear turbulence can be encountered 20 miles laterally from a severe storm is based on the understanding of how wind shear operates in relation to thunderstorms.

Severe thunderstorms are characterized by intense updrafts and downdrafts, which create significant changes in wind speed and direction in the atmosphere. This phenomenon leads to vertical and horizontal wind shear. Even when you are located some distance away from the actual thunderstorm, such as 20 miles laterally, the effects of these wind shifts can still be felt. This distance is a generally accepted estimate within aviation that represents the reach of turbulent air associated with severe weather systems.

This understanding is crucial for pilots and others in aviation so that they can anticipate the possibility of encountering turbulence even when they are not directly within or immediately adjacent to the storm itself. Consequently, being aware of this aspect of thunderstorm behavior is vital for ensuring safe flight operations.
