文摘The short term responses of 227326 lightning activities measured with LLP80-02 to 170 solar flares of importance 2 or greater over the Beijing-Tianjin-Hebei region around the summers of 1989-1994 are studied.In the region of 600×600 km 2,these are two areas of negative responses with a significance level better than 5×10 -3 .They are the Bohai Bay and the middle west of Hebei,both with a scale of several hundred kilometers.This means that the lightning activities in these areas decrease after flares.This gives rise to a new challenge to the mechanism of the effect of solar activities on the short-middle term weather and provides a new basis for further research.
