采集6类22种气象数据、风浪预报和船舶修造企业地理信息，探究各气象要素对室外焊接作业船舶修造工艺流程的影响。研制室外焊接作业气象风险预报模型，搭建专业的气象服务平台，形成即时气象监测超阈值告警、小时到日的气象风险动态预警及影响提示和应对措施等数字化服务产品，实现室外焊接作业气象风险从观测、预报预警到服务、应急处置的全流程闭环管理，有效提升企业气象风险防范能力和安全生产效率。通过实时更新的实况或预报数据，得到室外焊接作业相应的气象要素影响等级，采用函数最大值方法，取各因子气象风险等级中的最高等级，即符合风力、降水量、气温、对流天气条件之一即可判别为相应的风险，最终级别取最高的风险等级。假设室外焊接作业的气象风险等级为Y2，具体计算公式如下：Y2=max（Yw,Yr,Yt,Ym），其中Yw为风力对应的气象风险等级，当风力＞5级为Ⅰ级（高风险），当4级≤风力≤5级为Ⅱ级（中风险），当风力＜4级为Ⅲ级（低风险）；Yr为降水量对应的气象风险等级，当降雨量≥0.1毫米为Ⅰ级（高风险），当降雨量＜0.1毫米为Ⅲ级（低风险）；Yt为气温对应的气象风险等级，当气温＜0.0℃或气温≥30.0℃为Ⅰ级（高风险），当0.0℃≤气温≤5.0℃或25.0℃≤气温＜30.0℃为Ⅱ级（中风险），当5.0℃＜气温＜25.0℃为Ⅲ级（低风险）；Ym为对流天气对应的气象风险等级，在5km范围内，有闪电为Ⅰ级（高风险），无闪电为Ⅲ级（低风险）。假设Yw为Ⅰ级（高风险）,Yr为Ⅲ级（低风险），Yt为Ⅲ级（低风险）,Ym为Ⅲ级（低风险），最终Y2取其中最高风险等级Ⅰ级（高风险）。

This study collected 6 categories and 22 types of meteorological data, wind-wave forecasts, and geographic information of shipbuilding and repairing enterprises, to explore the impact of various meteorological factors on the shipbuilding and repairing process flow for outdoor welding operations.
Subsequently, we developed a meteorological risk prediction model for outdoor welding operations, built a professional meteorological service platform, and generated digital service products including real-time meteorological monitoring over-threshold alerts, hourly-to-daily dynamic meteorological risk early warnings with impact prompts and response measures. We realized the closed-loop management of the entire process of meteorological risk for outdoor welding operations, from observation, forecasting and early warning, to service provision and emergency disposal, effectively improving the enterprise's ability to prevent meteorological risks and the efficiency of safe production.

Based on real-time updated observed data or forecast data, the corresponding meteorological factor impact level for outdoor welding operations can be obtained. The function maximum method is adopted to select the highest level among the meteorological risk levels of each factor: meeting any one of the conditions of wind force, precipitation, air temperature, and convective weather can be judged as a corresponding risk, and the final level takes the highest risk level.

Assume that the meteorological risk level for outdoor welding operations is Y2, and the specific calculation formula is as follows:
Y2 = max(Yw, Yr, Yt, Ym)
where Yw is the meteorological risk level corresponding to wind force:
- Level I (High Risk) when wind force > Grade 5
- Level II (Medium Risk) when Grade 4 ≤ wind force ≤ Grade 5
- Level III (Low Risk) when wind force < Grade 4
Yr is the meteorological risk level corresponding to precipitation:
- Level I (High Risk) when rainfall ≥ 0.1 mm
- Level III (Low Risk) when rainfall < 0.1 mm
Yt is the meteorological risk level corresponding to air temperature:
- Level I (High Risk) when air temperature <0.0℃ or air temperature ≥30.0℃
- Level II (Medium Risk) when 0.0℃ ≤ air temperature ≤5.0℃ or 25.0℃ ≤ air temperature <30.0℃
- Level III (Low Risk) when 5.0℃ < air temperature <25.0℃
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 within 5 km

For example, assume that Yw is Level I (High Risk), Yr is Level III (Low Risk), Yt is Level III (Low Risk), and Ym is Level III (Low Risk); the final Y2 will take the highest risk level, Level I (High Risk).
