The Diurnal Variation of Turbopause Height.
Abstract
Utilizing chemical release observations, and recently reported turbopause heights based upon mass spectrometer measurements of the Ar/N2 ratio, the diurnal variability of turbopause height is determined. Separation of the data, on a seasonal basis, shows that there is a strong winter diurnal variability with turbulence carrying to its highest altitude (approximately 115 km) between sunset and midnight, and minimizing at the noon hour. The spring data shows a similar variability, but at an overall lower altitude than that of winter, and a possible latitudinal difference, while the fall results demonstrate no real diurnal variation, and an average turbopause height at approximately 106 km.
