This project aims to determine how the frequency of intense tropical and subtropical thunderstorms will change as a result of future global warming. Climate models project that the energy available to such storms will increase in the future, but the reasons for this increase in available energy, and the implications for thunderstorm activity, remain uncertain. Using observations and high-resolution models, the project expects to generate new knowledge of the mechanisms driving changes in intense thunderstorm activity under climate change, and to provide more accurate projections of the frequency of intense thunderstorms in a warmer climate. This project should deliver benefits to sectors of the economy such as agriculture and transportation, which are significantly exposed to such hazards.

该项目旨在确定热带和亚热带强烈雷暴的频率将如何随着未来全球变暖而变化。气候模型预测，未来此类风暴的可用能量将增加，但可用能量增加的原因以及对雷暴活动的影响仍然不确定。利用观测和高分辨率模型，该项目预计将产生关于气候变化下强雷暴活动变化的驱动机制的新知识，并提供关于温暖气候下强雷暴频率的更准确预测。这一项目应使农业和运输等严重受此类灾害影响的经济部门受益。
