| 摘 要： | 本文利用ECMWF逐日再分析资料(1961～2000年),主要从结构和水平传播包括经向传播和纬向传播方面对南海和南亚两个季风区的30～60天振荡进行了比较分析.研究结果发现,两个季风区的大气季节内振荡都存在明显的年际变化,但并没有出现同相或反相的变化关系.两个季风区ISO在结构上既有相似的地方也有不同点,在垂直结构上都...

| Abstract: | The ECMWF daily reanalysis data(1961-2000)are used to study the differences of intraseasonal oscillation(ISO) between the South China Sea(SCS) and South Asia(SA) monsoon regions through the band-pass filtering for 30-60 days.The comparative analysis of the ISO in these two regions is made mainly from the structure and horizontal propagation including zonal propagation and meridional propagation.It is found that the vertical structure of ISO in the SCS tilts westward more obviously than that in SA and that t... |
