Climate change enhances extreme rains more than the ordinary drizzle. New research shows that frontal rain increases the most, and illustrates why extreme rains caused by other phenomena are not equally affected. … In a recent study published in Geophysical Research Letters, she [Kjersti Konstali, University of Bergen] and her colleagues looked into the mechanisms making the heaviest rainfall not just more extreme, but more extreme relative to not quite as extreme rainfall. … The wettest days occur when cyclones march in with fronts and an atmospheric river—a powerful troika now and in the future. But of the three, the front causes the largest increase.
