A STUDY ON THE FLOOD PREMONITIONS IN ZHEJIANG PROVINCE

With a large number of data about flood and related phenomena, the premonitions of flood in Zhejiang Province are analysed systematically, which are 1) sunspot actions; 2) solar proton flare; 3) intersection eclipse year of perihelion; 4) anomaly of the earth's magnetic field; 5)anomaly of atmospheric circulation; 6) EL Nino event; 7) anomaly of sea water temperature in warm pool of the western Pacific Ocean; 8) typhoon landing in Zhejiang. Others include gathering of the nine planets, solar eclipse, polar migration, unusual change of the rotation speed of the earth, volcanic eruption and so on. It is shown that the more these premonitions reduplicate, the stronger the signals are, and the larger the flood magnitude is.
