Joost A. Businger
The 2003 Vilhelm Bjerknes Medal is awarded to Joost A. Businger for his fundamental contributions to the understanding of atmospheric turbulence and boundary layer processes and structure.
Joost Businger’s research has included instrument design, observational field progammes and the interpretation of their results, and the theory of the atmospheric boundary layer. He played a leading role in the development of the sonic anemometer-thermometer and in the organization of the 1976-77 Kansas field progamme. His theoretical work has elucidated the growth and structure of the boundary layer resulting from surface fluxes of heat, moisture and momentum, convective plumes within the layer, radiation and entrainment at the top of the layer.
