| 目的 研究不同统计方法下高原和高纬度地区低温极值的特征。方法 利用高原和高寒地区国家级地面气象观测站2010~2020年间的小时温度数据，研究不同严酷月基准条件下两地低温工作极值的变化情况。结果 3种严酷月基准条件下，高原地区低温严酷月相同，工作极值没有发生变化；高纬度地区低温严酷月发生变化，导致工作极值最大差值达到3.2 ℃。另外，3种条件下高原地区的低温工作极值均高于高纬度地区。结论 装备在典型地区服役过程中的环境工作极值统计应明确严酷月基准条件。 |
| 英文摘要: |
| The work aims to study the low temperature extreme characteristics of the plateau area and the high latitude area under different calculation methods. Specifically, the changing situation of the operational extremes of these two areas under different harsh monthly base conditions were researched by the precipitation temperature data of national meteorological observation stations from 2010 to 2020 of the plateau area and the high latitude area. Results showed that harsh moth and operational extremes of the plateau area had no change under three harsh monthly base conditions. But the harsh moth of the high latitude area changed, leading a maximum difference of 3.2 ℃ of operational extremes in the high latitude area. Additionally, the low temperature operational extremes of the plateau area were higher than that of the high latitude area. Therefore, the corresponding harsh monthly base condition should be clarified for the environmental operational extremes equipment in the service process of typical areas. |
