Explain why cumulus clouds are often observed to form, gradually disappear, and then reform in the same spot
As cumulus clouds grow, they shade the ground from the sun, which cuts off surface heating and upward convection. Without the continual supply of rising air, the cloud begins to erode as its droplets evaporate. As the cloud dissipates, surface heating begins again and regenerates another thermal, which becomes a new cumulus.
