Which type of jetstream can be expected to cause the greater turbulence?

The type of jetstream that is associated with a deep low-pressure trough is known to create greater turbulence due to its dynamic nature. When a jetstream curves significantly, especially in association with a deep trough, it indicates a strong wind gradient and varying airflows. This scenario often leads to a marked difference in wind speeds and direction over short distances, which can enhance turbulence. The powerful updrafts and downdrafts that occur in these areas, as well as the interactions with varying weather systems, contribute to the turbulence experienced by aircraft flying through such regions.

In contrast, a jetstream associated with wide isotherm spacing tends to indicate a more stable atmosphere with less turbulent activity. Likewise, a straight jetstream related to a high-pressure ridge generally entails smoother, less disturbed airflow. Although a northbound jetstream that curves to the east may also create areas of turbulence, it typically does not reach the same intensity as that found in the turbulence produced by a curving jetstream linked with a deep low-pressure trough.
