Small convective cumulus clouds often develop under weak updrafts conditions in the presence of strong thermal inversion layers. Observations show that cloud bases in these cases often lie below the lifting condensation level (LCL). Using an air parcel model we show that under such delicate conditions these clouds cannot be the result of classical thermals or plumes and that perturbations in relative humidity could be the mechanism responsible for their formation. The lecture will discuss the evidence and importance of such clouds and the proposed formation mechanism.
