Abstract
By using the materials of NCEP/NCAR global reanalysis monthly mean grid data(2.5°×2.5°)at 500hPa level every June from 1980 to 2013, we calculated NECV index and researched the relationship between East Asia blocking high voltage and the northeast cold vortex by synthetic analysis and correlation analysis. The results showed that when northeast cold was strong, there was significant negative height anomaly in the northeast, and the Okhotsk Sea region was positive height anomaly, there was a significant positive anomalies near the Ural Mountains. There was"+-+"type in Eurasian high latitudes zonal. This highly unusual situation provided large-scale circulation for the formation and maintenance of the northeast cold vortex. There was a good negative correlation between NECV and East Okhotsk blocking high that blocking high (hereinafter referred Okhotsk high) .when there was low height in northeast field, Okhotsk had high-altitude (the stronger the cold vortex, the stronger the Okhotsk high). While the Northeast cold vortex and low air circulation also had some contact.关键词
