北太平洋海温异常与黑龙江省夏季低温的联系及其长期预报
RELATIONSHIP BETWEEN THE ABNORMAL SEA TEMPERATURE ON THE NORTH PACIFIC AND COOL SUMMER IN HEILONGJIANG PROVINCE AND LONG RANGE FORECAST FOR IT

摘要: 黑龙江省是我国最北的省份,农业生产受夏季气温高低的影响很大.六十年代后期到七十年代,平均三、四年就有一次夏季低温冷害,严重的低温冷害,可给农业生产带来大幅度减广.分析表明,北太平洋海温的变化,通过海气关系可直接影响黑龙江省的气温.研究北太平洋海温的异常变化,可能是提高黑龙江省低温冷害长期预报有希望的途径之一.Abstract: There is a close relation between cool summer in Heilongjiang Province and the abnormal variation of sea temperature on the North Pacific.When the sea temperature is above the normal at 5°N-10°s,80°W-180°W in equator region on the East Pacific,the longitudinal degrees of the positive values in the south and negative values in the north will occur and the summer microtherm in Heilongjiang Province will occur correspondingly.The persistence of abnormal high temperature in the equator region on the East Pacific is over one year,and the microtherm process in Heilongjiang Province will be also over one year.
