【摘要】 在对浙江最主要的突发性地质滑坡、泥石流子体与降雨量的统计分析后,提出了有效降雨量概念,通过统计分析,获得了计算有效降雨量关系式和四个多发区的临界有效降雨量。针对滑坡、泥石流,应用MM5中尺度预报模式进行本地化,并结合卫星和雷达的客观雨量预报方法。三种客观预报雨量的方法互相补充。经2003年和2004年试报,对雨量预报和滑坡、泥石流预测有较好的效果。更多还原

【Abstract】 Based on statistic analysesbetween landslide,debris flow and precipitation,the efficient precipitation which will cause the landslide and debris flow events wasgiven.Then we got efficient precipitation formula,critical efficient precipitation in four high-risk zone for landslide or debris flow in the province.To better forecast landslide and debris flow,we localized mesoscale model,the well-known MM5,and the nowcasting technique of satellite and radar also were utilized.The three methods could supplement each other.After testing daily forecast duringthe period of 2003-2004,the result showed that the method has a quite good behavior in precipitation forecast and landslide,debris flowforecast.更多还原
