Protecting Canada's built environment against extreme wind and other natural disasters is necessary to save lives and sustain the prosperity of communities. Although significant progress has been made in wind engineering, the characteristics tornadoes and downbursts close to the ground, and their impacts on the built environment, are not clearly understood. The current design and testing methods for buildings, including essential buildings such as hospitals, fire stations and emergency shelters that must remain operational during an emergency, do not take tornadoes and downbursts into consideration.

保护加拿大的建筑环境免受极端风和其他自然灾害的影响对于拯救生命和维持社区繁荣至关重要。尽管风工程已取得重大进展，但接近地面的龙卷风和下击暴流的特征及其对建筑环境的影响尚不清楚。目前的建筑物设计和测试方法，包括医院、消防站和紧急避难所等在紧急情况下必须保持运行的重要建筑物，没有考虑龙卷风和下击暴流。
