Abstract:

The report documents and provides a users guide for a one-dimensional numerical model to study the effects of convection on the environment. The model combines a one-dimensional Lagrangian cumulus cloud model with the basic physical processes of cyclonic scale lifting, surface eddy mixing, cloud induced environmental subsidence, sub-cloud hydrometeor water evaporation and horizontal diffusion of the dissipating cloud. Included in this documentation are a detailed model description, derivation of the model equations, a basic flow diagram, a list of program mnemonics, a description of the input data format and a model listing and output from the National Center for Atmospheric Researchs Control Data 6600 and 7600 computers.
