Períodos
Osborne Reynolds (23 August 1842 – 21 February 1912)
Innovator in understanding of fluid dynamics. Transition from laminar to turbulent flow.
Created the Reynolds number, the ratio of inertial to viscous forces.Lord Rayleigh (12 November 1842 – 30 June 1919)
Elastic scattering of light by particles much smaller than the light's wavelength. Named "Rayleigh scattering,"
it explains the blue colour of the sky. Has Rayleigh number named after him, which describes instability.Lewis Richardson (11 October 1881 – 30 September 1953)
Atmospheric turbulence, has the Richardson number named after him.
"Big whirls have little whirls that feed on their velocity, and little whirls have lesser whirls and so on to viscosity."Henri Bénard (25 October 1874 – 29 March 1939)
Convection, and how heating from below produces convective cells, with
ascent in the centres and descent between cells.Sir Geoffrey Taylor (7 March 1886 – 27 June 1975)
Suggested that turbulence in the planetary boundary layer does not change its shape, size or other properties when advecting past a sensor.Walfrid Ekman (3 May 1874 – 9 March 1954)
Created the Ekman Spiral, explaining the balance between friction and the Coriolis force.
Used Ekman Spiral to describe transport of surface water perpendicular to wind directionTheodore von Kármán (11 May 1881 - 6 May 1963)
Made multiple theories on stability of laminar flow, turbulence and boundary layers among others.
has the von Kármán constant named after him, used to calculate fluxes of heat, mosture and momentum.Alexander Obukhov (5 May 1918 – 3 December 1989)
Contributed to statistical theory of turbulence and atmospheric physics. One of the founders of boundary layer meteorology.
Has the Obukhov length named after him, which combines thermal and dynamic instablilites to predict cloud streets.
