Abstract : The climatological behavior of the ballistic wind and density is examined using the means of equally weighted values of upper-air wind and density at altitudes 2 km apart. These mean values are termed integrated wind and density, respectively. Three integrated values of wind and density are used, one for the atmosphere below 12 km, another for the atmosphere below 16 km, and one for the zone below 24 km. Data from 25 stations in the Northern Hemisphere, chosen from widely diverse climatic regimes, are employed. The specific aspects of behavior examined are: the effects of variability on short-period means; comparison of monthly and seasonal statistics; the effects of estricted amounts of data; and the relation between integrated density and integrated wind.
