Abstract:Based on recent 55-year data,analysis is done of the circulations anomalies features associated with the western Pacific teleconnection pattern (WP) in winter and the relation to China's winter weather-climate.Results show that the winter climate of China is closely related to the WP teleconnection pattern.In the higher (lower) index years,negative (positive) anomalies appear in the middle-high latitude at 500 hPa height field,the middle-latitude west wind is strengthened (weakened),the circulation is zonal (meridional) pattern.Accordingly,the Siberian High and the East Asian winter monsoon are weaker(stronger) than normal.Moreover,the WP index positively correlates to the winter temperature and precipitation in China.In temperature aspect,significant correlations are concentrated in a region shaped like U capital,which begins from the eastern coast,goes to the south,then turns to the southwest region,while only eastern region of China is significant with respect to precipitation.
