摘要
本文从观测分析和数值试验两方面研究了冬季赤道中东太平洋海温和北极海冰覆盖面积的异常对太气环流的影响。结果表明赤道热源和极地冷源的变异是影响大气环流异常的两个重要方面因子,极地海冰变异与赤道太平洋海温异常对大气环流的影响具有同等重要的作用,必须引起足够的重视。
The effects of anomalies of the central-eastern equatorial pacific surface temperature and the arctic sea ice cover on the atmospheric general circulation in the winter season are studied by observational analysis and numerical experiments. It is found that the sea ice anomaly plays a role of same importance as the SST anomaly ( El Nino event) in the anomalous variation of the general circulation of the atmosphere. So one should pay great attention to the study of polar sea ice anomalies in the long-range forecast research.
