中国区地面气象要素极值分析

Extreme value analysis of surface meteorological elements in China

气象条件对布设于户外的设备设施使用寿命具有严重影响。分析各地区气象要素极值及极值出现的时间风险率和面积风险率,对设备设施的设计有重要意义。基于2000-2017年中国地区国家级地面站气象观测资料,开展地面气象要素极值及其单要素的时间风险率和设备工作极值分析,为考察各类设备环境适应性提供数据参考。

Meteorological conditions have serious impact on the service life of outdoor equipment and facilities.Therefore,it is important to analyze the extreme values of meteorological elements and the time and area risk rates in designing the equipment and facilities.Based on the meteorological observations of national surface weather stations in China from 2000 to 2017,the extreme values of surface meteorological elements,the time risk rate of a single element and the extreme values of equipment operation are analysed.The results can provide data reference for investigating the environmental adaptability of various equipment and facilities.
