Analysis on the Relationship between El Nino Event and Precipitation in Flood Season of the Yellow River Basin
A new El Nino event has been formed in equatorial central and eastern pacific during the period of August 2006 to February 2007. It is always accompanied with extreme weather/climate in a large scale when El Nino event occurs, so it seems that there is a high probability of abnormal precipitation in the flood season of 2007 in the Yellow River basin with the occurence of the new El Nino event. Based on the analysis of precipitation characteristics in flood season of the Yellow River basin after the appearance of El Nino event since 1951, result shows that there is a high probability of more precipitation in the flood season in the next year of El Nino event in the middle reaches of the Yellow River basin. In the past, it happened typical floods in the summer of 1954, 1958 and 1977, and in the autumn of 2003 in the middle stream of the Yellow River basin.
