Keith C. Heidorn, a Canadian meteorologist who calls himself the Weather Doctor, has written a substantial history of Beaufort’s contributions to weather observation and record keeping. He puts the Beaufort Wind Scale in historic context, including an illustration of a British frigate, the vessel Beaufort used to describe the effects of different winds on a ship’s sails.
