| Abstract: | The polar vortex's position in the midsummer of 2003 is analysed in this paper,it is found that the polar vortex leaned to the Western Hemisphere for a long time leads to weakening of the cold air which influences our country.That is the one of the important reasons why the west Pacific subtropical high was abnormally strong and the temperature was persistently high in the south of China. |

| Keywords: | Polar vortex Cold air West Pacific subtropical high Temperature continued high |
