What cloud types would indicate convective turbulence?

Towering cumulus clouds are a strong indicator of convective turbulence. These clouds form as a result of rising warm air, which creates vertical movements associated with convection. The development of towering cumulus indicates significant atmospheric instability and vigorous updrafts that can lead to turbulence, especially at lower altitudes where the growth and organization of the cloud can lead to varying thermal currents.

In contrast, cirrus clouds, while they can be associated with weather systems, typically occur at high altitudes and do not suggest significant turbulence in the vertical sense. Nimbostratus clouds indicate overcast skies with steady precipitation rather than turbulent conditions, as they are associated with widespread, stable air masses. Stratus clouds are generally low-level clouds that form in stable air, providing a uniform layer rather than the chaotic updrafts that characterize convective activity. Thus, towering cumulus clouds are the most relevant in predicting the presence of convective turbulence.
