Abstract : Cross sections through 2 trade cumulus clouds are presented which show the temperatures, turbulence, and water vapor content of the clouds and their environment, the cloud slope, and the external wind profile. The clouds were studied over the Caribbean Sea on the same afternoon in June, 1952, and were in widely differing phases of their life cycles. The measurements were made from a slow-flying PBY-6A aircrafts equipped with sensing instruments. Calculations made from the cross sections include total and dynamic entrainment, drafts, slopes, and water content. The Stommel-Malkus steady-state model appeared applicable to some clouds and gave self-consistent results. The data provide evidence on the formation and growth of larger trade cumulus clouds from several smailer ones and on the precedence in time of earlier cloud towers in th same locality.
