One of the most powerful of all weather systems, hurricanes are powered by the heat energy released by the condensation of water vapour.───所有天气系统中最强大的系统之一，飓风是由水蒸气凝结释放的热能所驱动的。
I have moved from trying to model and understand the distribution and evolution of water vapour.───我已经不再试图构建和理解水汽的分布和演变的理论模式了。
