A meteorological risk forecasting model for high-altitude operations is developed, and a professional meteorological service platform is built, forming digital service products including real-time meteorological monitoring exceedance threshold alarms, dynamic meteorological risk early warnings from hourly to daily scales along with impact prompts and response measures. The full-process closed-loop management of meteorological risks for high-altitude operations from observation, forecasting and early warning to service and emergency disposal is realized, effectively improving enterprises' meteorological risk prevention capabilities and work safety efficiency. Based on real-time updated real-time or forecast data, the meteorological element impact level corresponding to high-altitude operations is obtained, and the maximum function method is adopted to take the highest level among the meteorological risk levels of each factor. Assuming the meteorological risk level of high-altitude operations is Y4, the specific calculation formula is as follows: Y4 = max(Yw, Yr, Yt, Yv, Ym) Where Yw is the meteorological risk level corresponding to wind force: - Level Ⅰ (high risk) when wind force > 5; - Level Ⅱ (medium risk) when 4 ≤ wind force ≤5; - Level Ⅲ (low risk) when wind force <4. Yr is the meteorological risk level corresponding to precipitation: - Level Ⅰ (high risk) when rainfall ≥4.0 mm; - Level Ⅱ (medium risk) when 2.0 mm ≤ rainfall <4.0 mm; - Level Ⅲ (low risk) when rainfall <2.0 mm. Yt is the meteorological risk level corresponding to air temperature: - Level Ⅰ (high risk) when air temperature <0.0℃ or ≥37.0℃; - Level Ⅱ (medium risk) when 0.0℃ ≤ air temperature ≤3.0℃ or 35.0℃ ≤ air temperature <37.0℃; - Level Ⅲ (low risk) when 3.0℃ < air temperature <35.0℃. Yv is the meteorological risk level corresponding to visibility: - Level Ⅰ (high risk) when visibility <200 m; - Level Ⅱ (medium risk) when 200 m ≤ visibility ≤1000 m; - Level Ⅲ (low risk) when visibility >1000 m. Ym is the meteorological risk level corresponding to convective weather: - Level Ⅰ (high risk) when there is lightning within 5 km; - Level Ⅲ (low risk) when there is no lightning.
