This manuscript investigates the role of atmospheric stability on the intermittency of turbulence within the atmospheric boundary layer. Wind turbines are designed for a prescribed level of turbulence intensity but are required to operate under varying atmospheric stability conditions. Longitudinal and vertical velocity and virtual temperature increments are investigated under varying atmospheric stability conditions over numerous multi-day periods. The results indicate a complex relationship between stability and turbulence intermittency. The analysed data is shown to be leptokurtic on all time scales. Importantly, turbulence on small time scales is shown to be highly intermittent irrespective of atmospheric stability and poorly predicted by Gaussian statistics.
