Jean - Pierre Wolf of the University of Lyon 1 in France and his colleagues flashed femtosecond laser pulses on
individual water droplets that were less than 70 microns in diameter.
Indeed, conventional wisdom held that higher levels of aerosol pollution in the atmosphere should cool the earth's climate because aerosols can increase cloudiness; they not only reduce precipitation, which raises the water content in clouds, but they also increase the size of
the individual water droplets, which in turn causes more warming sunlight to be reflected back into space.
Hu's experiments, for example, show everything from the thickness of ice as it flows over a wing, the heat transfer of
individual water droplets as they freeze, the irregular speed of freezing droplets on a wing or blade and the finger - like patterns of ice formation.
