Henry Charnock Explained

Henry Charnock ^[1] (25 December 1920  - 28 November 1997) was a British meteorologist.^[2] He is well known for his work on surface roughness and wind stress over water surfaces. The now named "Charnock's relationship" describes the aerodynamic roughness length,

z _{0} , over a water surface by:^[3] z _{0=C} u ^{2 /g} _{*}

where

u _{*} is the friction velocity and g is the acceleration due to gravity (typically the Standard gravity). C is Charnock's proportionality constant.

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