【摘要】 <正> 前人研究指出,强火山爆发时,把大量火山灰喷入平流层。0.5—1年内即可扩展到全球,它可以使全球平均气温下降0.5℃。本文主要揭示了近34年来,强火山爆发使全球平均气温降低这一微弱信息,经过大尺度海气相互作用调节、放大之后,使西太平洋副热带高压、赤道辐合带、北太平洋海温距平场转折,并容易发生厄尼诺的规律性。指出强火山爆发可能是厄尼诺发生的重要原因之一。更多还原

【Abstract】 In this paper, the relation of the subtropical high over the North Western Pacific, the equatorial covergence zone, the anomaly of SST departure of the North Pacific and formation of an El Nino event to violent eruption of volcanoes in recent thirty four years are studied. It has been found that the violent volcano eruption has important effect to EL Nino event, and EL Nino event appeared in the sixteenth month to twenty eighth month after the violently volcano eruption.更多还原
