| Abstract | ||
| Many of the potential rain-bearing clouds in tropical and semi-tropical countries are convective in nature and their tops often not exceeding the height of the freezing level. Some aspects of cumulus clouds are successfully captured by a thermal or plume model. These build on the intuition that a cloud, thought of as a bubble, will move up faster if the initial buoyancy is larger, and if the initial bubble size is larger. The aim of this work is to use the thermal plume theory to construct a simple one-dimensional cloud model. Results showed that if many small clouds are thermally generated in succession, they will tend to merge with each other after a while, which then works to effectively increase the size, buoyancy, and rate of ascent of the composite thermal. | ||
