Abstract: In this paper,the teleconnections of 5-day averaged 500 hPa height field in northern hemisphere winter are analysed,and six teleconnection patterns are summed up.The Pacific/Northern America (PNA),Western Pacific (WP) and Western Atlantic (WA) pattern are same as the teleconnection patterns of monthly averaged 500 hPa height field suggested by wallace.The Atlantic/Eurasia pattern (AEA) and it's subpattern (AEAS) are consistent with the propagations of the barotropical Rossby wave of wave number 3 and wave number 5 in spherical surface.The teleconnection of southeastern Asia pattern (SEA) may be related to the response of high latitude circulation to the low latitude forcing as shown by some numerical simulations.
