Rapid rain squalls are intensifying and climate variability cannot explain it

Powerful, short-lived rainfall events in Sydney are intensifying to new extremes, increasing by 40% over the past 20 years, new research shows. The results, published in Science, suggest that extreme sub-hourly rainfall could be increasing much faster than previously thought. Rapid rain squalls, also known as “intra-hourly heavy rain,” are the most extreme and destructive […]
