覆冰气象指数法在福建山区覆冰重现期确定中的应用
|
摘要
以福建省永安市西部山区发生的罕见覆冰事件为例,利用永安市气象站及九仙山气象站建站以来的气温、降水量、相对湿度、风速、日照时数等相关气象要素构建工程区域气象数据系列,建立更加适用于工程区域的覆冰气象指数赋值原则,用以分析罕见覆冰事件的重现期,为山区输电线路工程在电线积冰资料匮乏地区确定调查覆冰重现期提供参考。
Take the rare icing phenomenon happened in western mountainous regions of Yong' an city as an example,use the climate data mainly from Yong' an Meteorological station and Jiuxianshan Meteorological station,, such as temperature, precipitation, relative humidity, wind speed and sunshine duration, to build meteorological data series and constrauct a new principle of icing meteorological index suiting for the analyzing area to analyze the return period of the rare icing phenomenon, which provide a reference for transmission line engineering in data deficient mountain area to determine the return period of rare icing phenomenon.
