RESEARCH ON INTERANNUAL CHANGE ABOUT TELECONNECTION OF GENERAL CIRCULATION IN SUMMER DURING 1980s OVER THE NORTHERN HEMISPHERE

PDF

  • In the paper the 5°×10°latitude-longitude grid point data of daily 500 hPa geopotential height over the Northern Hemisphere(NH) in summer(June-August) during 1980s are used.The base point(20°N,120°E) is selected to calculate point correlation between the base point and other grid points.We find that the summer heat source anomaly of the tropical western Pacific causes anomaly of summer general circulation over NH and teleconnection of general circulation similar to PNA pattern forms from East Asia to North America.The teleconnections show great interannual changes.
