Abstract
The assumption is made that the large-scale mixing properties of the atmosphere are related to the time and spatial variances of the winds. Data on the time standard deviations is presented for levels from the surface to about 75 km based on balloon and rocket soundings. The monthly and year to year variations in the 15–30 km region and the average seasonal variation for the 30–75 km region are examined. An attempt to relate the time and space distributions of some radioactive and airglow tracers to the wind data is made.
