Land-falling tropical cyclones on the queensland coast -and implications of climate change for wind loads

摘要

ABSTRACT This paper reviews the numbers of tropical cyclones in the Coral Sea and the landfalling cyclones that have impacted the east coast of Queensland since 1969, with particular emphasis on those of Category 4 strength and above since 2011. It suggests that an apparent trend of increasing strength may be emerging that is consistent with climate modelling based on numerical weather models, and with other more recent studies. Some proposed revisions to the Australian Standard for Wind Actions, AS/NZS 1170.2, resulting from this are also discussed; this includes for the first time in the Standard, a ‘climate change multiplier’.
