Abstract:
By using the power spectrum analysis, the interannual variation of medium-range oscillation charac-teristics in the upper troposphere over the subtropical region in China during June-August, 1966－1981 is studied. The quasi-two and quasi-one week oscillations are the two major oscillations generally existing in the subtropical region, and their intensities have obvious quasi-triennial variation period. These medium-range oscillation characteristics are closely related to the South Asian high, and in some degree to the summer precipitation in China. The quasi-two week oscillation is probably a display of the inherent oscillation of the south Asian high itself, and the quasi-one week oscillation is probably that of the forced oscillation from westerly disturbances.

Abstract: By using the power spectrum analysis, the interannual variation of medium-range oscillation charac-teristics in the upper troposphere over the subtropical region in China during June-August, 1966－1981 is studied. The quasi-two and quasi-one week oscillations are the two major oscillations generally existing in the subtropical region, and their intensities have obvious quasi-triennial variation period. These medium-range oscillation characteristics are closely related to the South Asian high, and in some degree to the summer precipitation in China. The quasi-two week oscillation is probably a display of the inherent oscillation of the south Asian high itself, and the quasi-one week oscillation is probably that of the forced oscillation from westerly disturbances.
