    • Abstract
  • By using 500hPa winter daily data of height from 1971 to 1989, the spatial and temporal spectral analysis is investigated. The main medium-range oscillalions of total amount and every components of The angular momentum transport at 70°N, 500N and 30°N and their coherence feature are revealed. The same analysis is also carried out preliminarily in order to obtain the difference of above feature at preceding winters of several anomalous Meiyu years in 1971-1984.
