Summer thunderstorms become much more fierce when they collide with a city than they would otherwise be in the open countryside, according to research led by Princeton engineers.
Alexandros A. Ntelekos and James A. Smith of Princeton University’s School of Engineering and Applied Science based their conclusion on computer models and detailed observations of an extreme thunderstorm that hit Baltimore in July of 2004.
Their modeling suggests that the city of Baltimore experienced about 30 percent more rainfall than the region it occupies would have experienced had there been no buildings where the city now sits.
