The International Commission on Clouds was a specialized international agency of the International Meteorological Organization (IMO), founded during the International Conference of Directors of Meteorological Observatories in March 1913. During the conference, M. E. Durand-Gréville, a French meteorologist, published and presented research about squall lines and tornadoes. The research presented by Durand-Gréville regarded how tornadoes can form in any "squall-zones" of squall lines, which can be detected through barometers. This led to the creation of the "law of squalls" as well as the creation of the International Commission on Clouds.[1]

The commission was chaired by MM. H. Hildebrandsson, a meteorologist and professor in Sweden, Shaw of the United Kingdom, and E. Durand-Gréville of France.[1]
