Drops Falling in Clouds Make More Drops

Publication in Physical Review Letters

Published on : October 5, 2017

In collaboration with the ENS de Lyon's physics lab

Alain Pumir, of the ENS de Lyon's physics lab and a team led by Eberhard Bodenschatz of the Max Planck Institute for Dynamics and Self-Organization in Göttingen, Germany, has managed to create a similar rain-seeding phenomenon in controlled laboratory conditions.
"The work is an important step in basic atmospheric science", says meteorologist Juan Pedro Mellado of the Max Planck Institute for Meteorology in Hamburg. Doing a similar experiment in atmospheric conditions is difficult because it’s hard to reproduce the right environmental conditions on a small scale or to closely monitor the wake behind the drop. He says the work provides "a clear example of how laboratory experiments of idealized problems can help us better understand atmospheric processes".
