摘要
利用ECMWF的格点资料,研究了1980年6—9月200hPa上的双周振荡过程。发现在40—180°E范围内存在两支经向波导,分别位于60°E和120°E附近。两支波导形成的原因不同,在季风系统的中期变动中所起的作用也不同。
In this paper, the ECWMF grid data are used to investigate the biweekly oscillation at 200hPa from June to September, 1980, across 40-180°E. Two low - frequency waveguides locate near 60°E and 120°E. Contributing factors for their formation are different from each other, so are the role they play in the mediumterm variations of monsoon systems.
