An Analysis of Upper-Air Observations at McMurdo Sound, Antarctica

摘要

The height of the tropopause is determined at McMurdo Sound for January 1957 and July 1957 using three methods. The tropopause was found to be lower in summer than in winter.nMean temperature soundings for January 1957, July 1957, and October 1957 were determined to study the effect of the sun's rays on the heating of the Antarctic atmosphere. It was found that radiational heating of the atmosphere by the sun seemed to be the pre¬dominant process.nMean vertical wind profiles for July 1957 at McMurdo Sound reveal that the wind increases to the top of the sounding, whereas during January 1957 at wind maximum is present in the vicinity of the tropopause.
