Semi-important events that are semi-relevant to meteorology: August 12
1885 - Physicist Jean Cabannes is born. He specialized in optics. He showed how gas molecules diffused light (pure gases can scatter light). He, along with Jean Dufay, calculated the height of the ozone layer. Additionally, he, Daure, and Rocard showed that gases diffusing monochromatic light could also change their wavelength. This is known as The Cabannes-Daure effect.
1953 - A 7.3 magnitude earthquake strikes the Greek islands of Zakynthos and Kefalonia.
