He served in the Radar branch of the RAF during the Second World War as a Flight-lieutenant. After being awarded a first class degree in physics by the University of London he was in 1948 appointed lecturer in the postgraduate Department of Meteorology at Imperial College, London.[6] He married Doreen Jones, with whom he had two sons.
Career
He worked at Imperial College from 1948 to 1965, being appointed Professor of Cloud Physics in 1961. His work concerned the physical processes involved in the formation of clouds and the release of rain, snow or hail and led to the Mason Equation, which defines the growth or evaporation of small water droplets.
From 1965 to 1983 he was Director of the UK Meteorological Office at Bracknell where he also developed theories to explain how electric charge is separated in thunderclouds, ultimately leading to lightning.[6] Mason was elected a Fellow at Imperial College in 1974. His doctoral students included John Latham.[7]
John Mason died in 2015.[8] After his death, the Sir John Mason Academic Trust,[9] was established by his family and is chaired by his son, Professor Nigel Mason OBE, currently Head of the School of Physical Sciences at the University of Kent.
The National Portrait Gallery contains a portrait of Mason.[21] In 2004, Mason opened the Mason Centre for Environmental Flows at the University of Manchester. In 2006, an endowment from Mason enabled the Royal Meteorological Society to establish the Mason Gold Medal.[22] Mason was also Chairman of the British Physics Olympiad Committee.
