Description
Herminia Torelló-Sentelles and four co-authors show how cities slow storms down, and so pile up rain and flood risk. Their study, from two thousand twenty-five, joins radar reads with storm sims.
How storms move over towns may sway how much rain falls and how floods rise. The team tracked lone rain cells over eight towns, and matched their pace by the town to a pace up-wind. Next they simmed ten heavy rain runs over one town, with and sans the town's build. Cells slowed over and past most towns. The sims showed the same: winds at cloud height eased. Warm town ground lifts drafts, which brake the winds. More rain, not just pace, drives most of the flood gain.
