The type of cloud pattern associated with mesoscale cellular convection is open cell convective clouds. This type of convection occurs on a small scale and is characterized by the development of clusters of convective clouds that form in patterns resembling cells. These open cells generally appear as clear areas between clouds, with the surrounding clouds often exhibiting higher thermal uplift and a more organized structure compared to other types of convection.

Open cell convective clouds are typically associated with a relatively stable atmosphere where the boundary layer is capped. The convection may lead to the formation of clouds that have distinct flat tops, and they can often evolve into larger cloud formations if the atmospheric conditions permit. This pattern is especially observable in marine environments or areas where cooler air moves over warmer surfaces.

The other options represent different types of cloud formations that do not align with the characteristics of mesoscale cellular convection. For example, stratus clouds are uniform and layered, cirrus clouds are high-altitude wispy clouds, and cumulonimbus clouds usually indicate more persistent and severe weather patterns associated with significant convection, rather than the cellular, organized pattern seen in open cell convection.
