Cities Boosted Rain, Sent Storms to the Suburbs During Europe’s Deadly Summer Floods

When it comes to extreme weather, climate change usually gets all the attention. 

When it comes to extreme weather, climate change usually gets all the attention. But according to a study from The University of Texas at Austin and two universities in China, the unique effects of cities – which can intensify storms and influence where rain falls – need to be accounted for as well.

“In addition to cutting emissions we need to recognize that understanding the effects of urbanization is part of the solution,” said Dev Niyogi, a professor in the UT Jackson School of Geosciences and Cockrell School of Engineering.

Niyogi is a co-author on a study published in Geophysical Research Letters that used computer models to investigate how cities and climate change influenced the rainstorm that struck the Rotterdam-Brussels-Cologne metropolitan region on July 14, 2021.

The model found that the interplay of large-scale climate and local-scale urbanization intensified the storm, causing more rainfall than either climate or urbanization on its own.
