云南省地质灾害气象风险预警技术改进及应用检验OA北大核心CSTPCD
Improvement and Application Verification of Meteorological Risk Early Warning Technology for Geological Disasters in Yunnan Province
利用2014-2022年云南省地质灾害数据和气象降水资料,开展有效降水量致灾概率研究,并结合地质灾害易发因子,分区建立了新一代精细化地质灾害气象风险预警模型,并对模型性能开展了应用检验.结果表明:新建的地质灾害气象风险预警模型提高了预警产品的时空分辨率和准确率,应用效果良好.模型能提前较好地反映出区域性强降水过程背景下的气象风险预警等级;对较难预报的局地强降水,也可以通过实时更新的监测预警产品给出风险加强的趋势,提前发出地质灾害气象风险预警信息;能直接客观反映出极端强降水背景下的气象风险高级别预警,起到较好的预警提示作用.
Using geological disaster data and meteorological precipitation data from 2014 to 2022 in Yunnan Province to conduct a study on the disaster probability caused by effective rainfall.Combined with the geological dis-aster-prone factors,a new generation of refined geological disaster meteorological risk early warning model is es-tablished,and an application test on the performance of the model is carried out.The results show that the new geo-logical disaster meteorological risk early warning model can improve the spatio-temporal resolution and accuracy of the early warning product,and the application effect is good.The model can better reflect the meteorological risk warning level under the background of regional heavy precipitation processes in advance.For the local heavy precip-itation that is difficult to forecast、the trend of risk strengthening can be given through real-time updated monito-ring and warning products,so the early warning information of geological disaster meteorological risk can be issued in advance.It can objectively reflect the high-level warning of meteorological risks under the background of ex-treme heavy rainfall,playing a good warning and prompt role.
