Erik Anton Björkdal was a Swedish meteorologist who studied at the Bergen School of Meteorology where the theory of fronts was developed. His contribution was mainly in the field of dynamic meteorology. Among his works, mention must be made of the correlation between the tropopause geopotential and the troposphere temperature.[1]

Biography

Björkdal was born on 21 February 1899 in Vimmerby, Sweden.[2] After high school, he was admitted to the University of Uppsala and graduated in 1920. However, in 1919 he was employed by Vilhelm Bjerknes as an assistant at the Bergen School of Meteorology.[3] After graduation, he was transferred to the Norwegian Meteorological Institute in Oslo where he became Division Chief in 1937.[2]

During the Second World War, he replaced the director of the Institute, Dr. Th. Hesselberg, who was absent for a period of time because of health problems. He eventually became head of meteorology at the Swedish Meteorological and Hydrological Institute in Stockholm in 1949.[2]

Björkdal was an active collaborator at the international level with the World Meteorological Organization (WMO), among others with the Synoptic Meteorological Commission, of which he was Vice-President from 1951, and with the Telecommunications Subcommittee, of which he was president from 1949.[2]

Björkdal died on May 30, 1952 in Stockholm.[2]

gollark: It also seems to function as a plausibly deniable way to ban end to end encryption (it never mentions it explicitly but does have a mechanism to force technology companies to make their service amenable to centralised monitoring).

gollark: The UK government is also working on the incredibly ææææ "online safety bill", which obliges online things to ban "harmful content" (not illegal, "harmful").

gollark: I do know about this.

gollark: It doesn't help that various governments and such also seem to not want anonymous online communications.

gollark: Maybe people will get sufficiently annoyed by this sort of practice to get it to stop at some point, or maybe we're doomed to a dystopia of social acceptability.
