     The wavetrains of EUP,PNA,ASA and RSA,perhaps, are the main propogation routes of the low frequency perturbation in the atmospheric circulation. Consequently the 30-60 day oscillation in the region of middle high and low latitude or in the Northern and Southern Hemisphere keeps in contact with each other. It is suggested,that,the middle equatorial Pacific and Atlantic are the paths through which 30-60 day oscillations in the Northern and Southern Hemisphere interact.
     EUP,PNA,ASA和RSA波列可能是全球大气低频扰动传播的主要路径,30~60d低频扰动在波列路径上的传播具有很大的一致性和系统性,从而使中高纬和热带地区、以及南北半球的30~60d大气振荡相互联系起来,而且可以认为,赤道中太平洋和赤道中大西洋地区是南北半球30~60d低频振荡间相互作用和相互联系的重要通道。

The global characteristics of intraseasonal ( 30-60 day ) atmospheric oscillation are investigated by using ECMWF data . The distribution of kinetic energy of the 30 - 60 day oscillation shows it is a very large in the high latitudes. This means the 30-60 day atmospheric oscillation is prominent in the high latitudes as in the tropical atmosphere . The 30 - 60 day oscillations in the middle-high latitudes are clearly different properties with that in the tropical atmosphere . They are barotropical modes for...

The global characteristics of intraseasonal ( 30-60 day ) atmospheric oscillation are investigated by using ECMWF data . The distribution of kinetic energy of the 30 - 60 day oscillation shows it is a very large in the high latitudes. This means the 30-60 day atmospheric oscillation is prominent in the high latitudes as in the tropical atmosphere . The 30 - 60 day oscillations in the middle-high latitudes are clearly different properties with that in the tropical atmosphere . They are barotropical modes for vertical structure , dominated by perturbances of zonal wavenumbers 2 - 4 and propagate slowly westwards. The low - frequency teleconnection is very obvious for the 30 - 60 day oscillation . There are mainly the Europe-Asia-Pacific (EAP) pattern and PNA pattern in the Northern Hemisphere, and the Australia- South Africa ( ASA ) pattern and Round South America ( RSA ) pattern . Especially , above - low - frequency teleconnection patterns link each other in the global atmosphere and constitute two low - frequency wavetrains , i . e . EAP-ASA wavetrain and PNA-RSA wavetrain, or EAP-RSA wavetrain and ASA-PNA-wavetrain. There are obvious interactions of 30-60 day oscillation between the Northern and Southern Hemisphere, and their three fundamental processes are discussed in this paper.

利用ECMWF格点资料,分析研究了大气季节内(30—60天)振荡的全球特征。30—60天振荡动能的分布表明高纬度地区要比赤道地区大得多。说明那里有较突出的30—60天振荡。中高纬度地区的30—60天振荡与热带有明显不同,垂直结构为正压模态,以纬向2—4波为主,多为向酉传播。30—60天振荡存在明显的低频遥相关,北半球主要为欧亚—太平洋(EAP)型和PNA型,南半球主要有澳洲—南非(ASA)型和环南美(RSA)型,并且在全球范围构成南北半球相互衔接的低频波列,即EAP-ASA波列和PNA-RSA波列。南北半球30—60天大气振荡有明显的相互影响,本文研究了南北半球30—60天振荡相互影响的3种主要过程。

On the basis of monthly mean sea surface temperature and sea level anomaly in the tropical Pacific, as well as longwave radiation and 850 hPa zonal wind anomaly over the tropical Pacific provided by the Climate Analysis Center and TOGA Sea Level Center of USA, and National Meteorology Bureau of China, the reason and the feature for 1986-1987 prolonged El Nino event are analyzed, and compared with 1982-1983 and 1991-1992 prolonged El Nino events.It is pointed out that the main reason for the longer duration of El Nino events is due to the variation of atmospheric circulation with half a year cycle over the tropical Pacific and strengthened atmospheric fluctuation over both sides at the north and south of the equator, which make anomalous atmospheric parameters subsequently occur with half a year time interval.

利用我国及美国国家气象局提供的热带太平洋月平均海温、水位、地球向外长波辐射和850hPa纬向风资料,对1980年以来的三次厄尔尼诺(El Ni(?)o)事件延长原因及其特征作一分析和探讨。文章指出,El Ni(?)o事件延长的原因主要是:在El Ni(?)o事件发生后,热带太平洋大气环流半年左右的韵律活动及在赤道南、北两侧明显的大气振荡加强,从而使大气的El Ni(?)o异常过程间隔半年相继发生。

In this paper, the relations between the 30-50 day atmospheric oscillation over the western tropical Pacific and subtropical high(SH) activities over the Pacific and the Sichuan Basin's flood-drought in summer are analysed. The result shows that the atmospheric low- frequency oscillation (ALFO) over the western tropical Pacific has a definite influence on SH over the Pacific. Within Sichuan Basin, the 30-50 day oscillation of rainfall in the east has a phase contrary to that in the west, and the phase of low-frequency...

In this paper, the relations between the 30-50 day atmospheric oscillation over the western tropical Pacific and subtropical high(SH) activities over the Pacific and the Sichuan Basin's flood-drought in summer are analysed. The result shows that the atmospheric low- frequency oscillation (ALFO) over the western tropical Pacific has a definite influence on SH over the Pacific. Within Sichuan Basin, the 30-50 day oscillation of rainfall in the east has a phase contrary to that in the west, and the phase of low-frequency oscillation of rainfall in the east (west) is contrary to (same as) that the ALFO over of the western tropical Pacific. Finally,it is pointed out that inducing the displacement of the center and west ridge-point of SH over the Pacific in the west-east direction, the ALFO over the western tropical Pacific results in the Sichuan Basin' s flood- drought anomaly in summer.
