BOMEX non-precipitating shallow cumulus

Still WIP, github issue: https://github.com/leifdenby/moistconvection/issues/3

Observational campaign EOL link: https://www.eol.ucar.edu/field_projects/bomex

Field experiment published in Holland and Rasmusson (1973) and Nitta and Esbensen (1974).

LES setup published in Siebesma, A. P., and coauthors, 2003: A large-eddy simulation intercomparison study of shallow cumulus convection. J. Atmos. Sci., 60, 1201-1219

Aims

• primary object to determine the rate of transfer of water vapor, heat and

Characteristics (needs verifying):

• no precipitation (precipitation was turned of in microphysics of original intercomparison)

• no cloud-deck formed at inversion height (which was observed in ATEX case)

Conclusions from observation

• condensation and evaporation processes associated with the development and dissipation of trade-wind cumulus can make a significant contribution to the heat balance of the cloud and trade wind inversion layers
