1991年初夏江淮大水的天文因素──太阳质子耀斑爆发

Astronomical Factor for the Occurrence of the Extraorchary Flood along the Yaugtze Huaihe Rivers During Early Summer,1991─The Bursts of Solar Proton Flares

  • 摘要: 研究了1991年初夏江淮大水前,北半球环流的异常与太阳上的一系列质子耀斑之间的关系.研究结果表明:太阳上连续不断的质于耀斑爆发是1991年初夏江淮大水的重要天文因素.太阳质子耀斑可能触发或加剧了极涡的冷空气南下,低空西南急流的东移和西太平洋副热带高压的西伸北移过程.由于冷热气流多次在长江中下游和淮河地区相遇.因而形成了频繁的暴雨和特大暴雨过程,造成了江淮地区的特大洪涝灾害.

     

    Abstract: The relationship between anomalous circulation in the Northern hemisphere and a series of solar proton flares occurred before the severe floods along the Yangtze-Huaihe Rivers during early summer, 1991 is researched. The results indicate that the continuous bursts of the large proton flares on solar disk is believed to be an important astronomical factor for the occurrence of the floods. The solar proton flares may trigger or intensify the process of the southward shift of cold air from polar vortex, the eastward shift of the low southwest jet flows and the west-hor-thward shift of the subtropical high in the west Pacific. Due to the frequent meeting of the cold and hot airflow along the middle-lower reaches of Yangtze River and Huaihe Rivers, it formed frequent processes of the heavy and heaviest rainfalls and then lead to the extraordinary flood along the Yangtze-Huaihe Rivers during early summer, 1991.
