WIND AND TEMPERATURE PROFILES NEAR THE GROUND IN STABLE STRATIFICATION.
Observed wind and temperature profiles from O'Neill, Nebraska and Antarctica are analysed to determine their characteristics in inversion conditions. Analyses of the similarity between wind and temperature profiles are presented. These show that the profiles are generally similar when the Richa...

Observed wind and temperature profiles from O'Neill, Nebraska and Antarctica are analysed to determine their characteristics in inversion conditions. Analyses of the similarity between wind and temperature profiles are presented. These show that the profiles are generally similar when the Richardson number is small.

It is shown that the log-linear wind profile fits the observations well for Richardson numbers less than about 0.14. The constant in the longlinear equation is found to have a value of approximately seven in stable air, implying a critical gradient Richardson number of 1/7.
