| 英文摘要 | The low frequency oscillation in both hemispheres and its possible role in the dust weather storm events over north china in 2002 are analyzed as a case study. results show that the aleutian low is linked with the circumpolar vortex in the southern hemisphere on a 30-60-day oscillation, with a weak circumpolar vortex tending to deepen the aleutian low which may be helpful for the generation of dust storm events. the possible mechanism behind this is the inter-hemispheric interaction of the mean meridional circulation, with the major variability over east asia. the zonal mean westerly wind at high latitudes of the southern hemisphere in the upper level troposphere may lead that of the northern hemisphere, which then impacts the local circulation in the northern hemisphere. thus, the low frequency oscillation teleconnection is one possible linkage in the coupling between the southern hemisphere circulation and dust events over north china. however, the interannual variation of the low frequency oscillation is unclear. |
