By studying satellite imagery of London and Paris, scientists discovered that during the spring and summer, the modern megacities are persistently cloudier in the afternoon and evening, by several percentage points, than nearby rural areas. Using ground-based observations in London, the researchers suggest the heat retained by buildings into the late afternoon drives turbulence in the air, feeding moisture to the clouds, they report this month in Climate and Atmospheric Science.Read more of this story at Slashdot.
