Which cloud type is an indicator of convective turbulence?

Towering cumulus clouds are an indicator of convective turbulence because they are formed through strong vertical lift and are associated with unstable atmospheric conditions. These clouds develop due to warm air rising rapidly, leading to significant updrafts and sometimes downdrafts. The turbulent air movements are a result of the strong thermal currents and can cause varying wind shear and turbulence, particularly as they grow in height and intensity.

While cumulus clouds also indicate some degree of convection, towering cumulus, which are larger and more developed, point to more vigorous vertical movements and turbulence. Stratus clouds, characterized by their uniform and stable layer, do not exhibit the same convective properties, nor do cirrus clouds, which are high-altitude and typically represent stable atmospheric conditions. Therefore, towering cumulus clouds are the clearest indicators of potential convective turbulence in the atmosphere.
