Abstract
Two zero-order bulk models (ZOMs) are developed for the velocity, buoyancy, and moisture of a cloud-free barotropic convective boundary layer (CBL) that grows into a linearly stratified atmosphere. The models differ in the entrainment closure assumption: in the first one, termed the ‘‘energetics-based model,’’ the negative and positive areas of the buoyancy flux are assumed to match between the model and the actual CBL; in the second one, termed the ‘‘geometric-based model,’’ the...
