AI reveals how a warming climate will intensify NZ's most extreme downpours
The most damaging weather events are the record-breaking "one-in-100-year" disasters communities have usually only seen once.
Recent research highlights how climate warming will intensify New Zealand's most extreme downpours. Weather events previously considered rare are expected to become more severe due to climate change. Scientists used artificial intelligence to simulate various future scenarios, revealing larger increases in rainfall intensity for infrequent events compared to more common heavy rainfall.
In a future with rising greenhouse gases, the amount of rain during a one-in-100-year event could increase by about 9% per degree of warming, while heavier daily downpours might rise by around 5.6% per degree. This study emphasizes the importance of considering both average increases and the range of possible outcomes, as natural variability and small differences in starting conditions can lead to vastly different results.
