Henry Charnock

Henry Charnock CBE FRS[1] (25 December 1920 – 28 November 1997), often credited as H. Charnock, was a British meteorologist.[2] He is well known for his work on surface roughness and wind stress over water surfaces. The now named "Charnok's relationship" describes the aerodynamic roughness length, , over a water surface by:[3]

where is the friction velocity and is the acceleration due to gravity (typically the Standard gravity). is Charnock's proportionality constant, shown to be 0.156.[4]

Charnock was President of the International Union of Geodesy and Geophysics (IUGG) from 1971 to 1975.
