Modelling Turbulence in the Lower Atmosphere Using Richardson's Criterion

Abstract

Rawinsonde wind and temperature data have been used to determine Richardson's numbers for 1 km levels between 2 km and 25 km. A critical value of the gradient Richardson number of one has been used as an indicator of the likelihood of occurrence of turbulence. The patterns in the occurrence of turbulence have been investigated for the seasons and years from 1971-1975. A regression analysis was performed on data from 21 rawinsonde stations located within the continental United States.
