In Sweden, radio broadcast weather forecasts begun in 1926, and, starting in 1941, Liljequist was one of the recurrent meteorologists appearing in Swedish radio for many years. Following his debut, his peculiar dialect caused mass protests which, together with an attack published by the humorist Kar de Mumma in the paper Svenska Dagbladet, caused broadcast forecasts to be taken over by Swedish public service radio during the war.[1]
During his life Liljequist wrote several books related to his field, besides textbooks on climatology and meteorology also overviews of Swedish polar history and research.
