【摘要】 本文对澳洲东岸两站17年的纬向风进行了谱分析,发现高、低层都具有40—50天及21—25天的周期振动,这种振动与西北太平洋上Truk岛低层纬向风同样周期的振动相关较好。对40—50天周期的振动来说,澳洲东岸的纬向风超前8—11天,而21—25天周期的振动则是Truk岛的纬向风超前3天左右。更多还原

【Abstract】 The spectral analysis of two station zonal wind over East Australia has been studied. It was confirmed that the oscillation with period between 40-50 days and 21-25 days did exsist at both high and low levels. These oscillations are closely related with the oscillation of same period of zonal wind for Truk Island over Northwestern Pacific. The oscillation of 40-50 day period over East Australia is 8-11 days earlier than that over NW Pacific. But the oscillation of 21-25 day deriod over NW Pacific is 3 days earlier than that over East Australia.更多还原
