Sinikka wrote a sky-ku haiku for October’s #scicommchall!
Sinikka explains: Clouds form if it is so cold that water vapour condensates to droplets. Little particles – so small you can’t see them – are often the base for water molecules to settle and form such a droplet. The particle is a so called cloud condensation nuclei. Sulfur gases emitted by the ocean can form particles that act in that way. This is one of the many ways the ocean influences weather and climate.
