ARCTIC STRATOSPHERIC TEMPERATURES AND DENSITIES.
LITTON SYSTEMS INC MINNEAPOLIS MINN APPLIED SCIENCE DIV
Frequency distributions of temperature and density, their means and standard deviations, have been computed for two different definitions of season at specified height and pressure levels to 30 km and 10 mb for six Arctic stations using 1956 - 1960 data. A limited number of inter-level correlations were also computed for one definition of season at constant heights only. Differing seasonal definitions gave large differences in distribution characteristics. Distributions of temperature at corresponding pressure and height levels for identical season definitions were examined for significant differences but none were found. Sudden warmings were observed at all stations, but only one showed a bimodal temperature distribution for five years of combined data. Using shorter data periods, other stations also exhibited the bimodal form. Author
