Using a special heat-absorbing fabric, scientists from Spain, Belgium and Israel are trying to create "islands of heat," which would accelerate air currents and favour the formation of rain clouds, according to Jesús Vigo of the University of Salamanca, who is leading the project.
The scheme was announced at a mathematics conference yesterday at the University of Alicante. In effect, scientists are trying to imitate a pattern commonly observed around cities in satellite images taken by Nasa's "rain radar".
The concentration of concrete and asphalt makes city air warmer than surrounding areas, according to a study by Nasa's Goddard Space Flight Centre. The hot currents rise, blow and clash with the cooler suburban air. Under the right conditions, they form rain clouds. Because of this so-called "urban heat island" effect, monthly rainfall is about 28% greater between 20-40 miles downwind of cities, compared with upwind, the study found.
