Abstract
G. I. Taylor introduced two kinds of correlation functions to describe the nature of micro-turbulence in turbulent flow. Mean radius and mean life of micro-turbulence in the atmosphere were determined after consideration of such correlation functions and the following relations were found. where η is eddy kinematic viscosity, τ0 mean life and u' fluctuation of the velocity. where λ is mean radius of the micro-turbulence, molecular kinematic viscosity.
Numerical values of mean life and mean radius of the micro-trubulence in the atmosphere were calculated from observations and it was found that they are about 6cm. and 50 sec. respectively.
