摘　　要：1991年 5月— 6月期间的日面上强质子耀斑的连续爆发 ,被认为是 1 991年中国江淮特大洪水的重要天文因素。太阳质子耀斑触发和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、北抬过程。由于冷暖湿气流在江淮地区频繁地相遇 ,因此形成了多次暴雨和特大暴雨过程 ,从而诱发了 1The continuous bursts of the strong proton flares on the solar disk during May and June in 1991 are believed to be an important astronomical factor for inducing the extraodinary flood along the Yangtze and the Huaihe Rivers in China in 1991. 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 level southwest jets and the west northward shift of the subtropical high pressure in the west Pacific. Owing to cold and hot airflow is frequently met, so it formed the frequent processes of the heavy and extremely heavy rainfalls, then, led to the extraordinary flood along theYangtze and the Huaihe Rivers in China during the early summer in 1991.
