The initiation, development and subsequent maturation of tropical cyclones is known as tropical cyclogenesis. The detailed nature of tropical cyclogenesis continues to be under investigation by climatologists, and it is apparent that there is still much we need to learn. This section therefore concentrates on the primary reasons why and main processes how tropical cyclones form in the South Pacific region. In order to be able to understand these fundamentals, it is necessary to have a good grasp of how rising air masses undergo adiabatic cooling, which leads to condensation of water vapour and the simultaneous release of latent heat energy. The adiabatic process is not described here because existing texts on meteorology and physical geography give clear and comprehensive explanations (Barry and Chorley 1998, Strahler and Strahler 2006).
