云南省地质灾害气象风险预警技术改进及应用检验
Improvement and Application Verification of Meteorological Risk Early Warning Technology for Geological Disasters in Yunnan Province
摘要
Abstract
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.关键词
