冬季黑潮加热与东北地区夏季(6-8月)温度关系的初步分析

摘要: 从六个年代以来,气象学家对海气关系进行了广泛深入地研究,认为海洋是使长期天气过程发生异常的主要能源之一。 近几年,有人对西北太平洋加热效应作了研究后指出,冬季黑潮海域加热对副热带高压进退有影响,从而影响5、6月份长江下游的降水[1]。我们在研究东北地区夏季低温的长期天气过程时,发现了黑潮海域冬季与春季连续加热,对东北地区夏季温度影响也是很大的,尤其是冬季黑潮海域的加热关系更明显。据此,我们认为这个关系有重要的预报意义。Abstract: In this paper the monthlymean sensible heating fields of the Northwest Pacific Ocean have been calculated on the basis of observation data.It is shown that the anomalous heating of the Kuroshio region during winter-spring will affect the later positions of the long wave's trough and ridge in westerlies and the temperature in Northeast China.Therefore,the cold summer in Northeast China could be forecasted.
