John Somers Dines (18 June 1885 – 15 May 1980)[1] was an English meteorologist.

He worked with his father, at Pyrton Hill, Oxfordshire, for a year, carrying out investigations of the upper atmosphere.

In 1912, he became responsible for the new branch of the Met Office at South Farnborough, where investigations of wind structure for the Advisory Committee for Aeronautics were conducted.

Dobson in autumn 1913, he visited six stations in Germany to see how they dealt with forecasting and aviation work.

Dines had transferred to the Forecast Division by March 1916, and remained there for many years.
