摘要
利用太平洋海温、北半球500 hPa高度和长春夏季气温资料,研究了前期Nino-C区海温与我国东北地区夏季气温的关系。结果表明:前一年5～7月Nino-C区海温与东北地区夏季气温有密切关系,特别是在ENSO事件出现之后。厄尔尼诺年的次年东北地区夏季多高温,而拉尼娜年的次年,东北地区夏季低温更明显,这种关系可用于进行东北地区夏季气温的预测。另外,通过对海-气相互作用、韵律关系等的分析,得出了前期海温对东北地区夏季气温的可能影响途径。
Based on SST data of the Pacific,height field data at 500 hPa,and air temperature data of Changchun in summer,the relationship between antecedent SST of Nino-C area and air temperature over Northeast China in summer were studied.The results show that air temperature over Northeast China in summer is related to SST of Nino-C area in May to July of the previous year.It is rather significant after the year of ENSO event.Air temperature over Northeast China is higher in summer if the months May to July was in El Nino,and it is lower if the months May to July was in La Nina.Air temperature forecast can be given by this relationship.Based on the analysis of air-sea interaction and rhythm, possible path by which air temperature over Northeast China in summer was affected by antecedent SST of Nino-C area was studied.
