| Abstract: |
| 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. |
