云南省地质灾害精细化气象风险预警模型优化研究
Improvement on the Meteorological Forewarning Index of Geologic Hazard in Yunnan Province
摘要
Abstract
In order to improve the running forewarning model used for meteorological risk warning of geologic hazard in Yunnan Province,the precipitation data from regional automatic weather stations in Nujiang were used to calculate critical indices,and the risk division of geologic hazard was updated by the disaster geographic informa-tion.According to the research,continuous precipitation was the main type of the rainfall-triggered geologic haz-ard,and the excitation of heavy rain in short term was very important.The geologic hazard had obviously regional distribution characteristics in Nujiang.It was found that the improved forewarning model had a better effect of appli-cation in 2015 events,and the rate of vacancy forecast for high risk warning was decreased significant.Based on the research the spatial resolution of the meteorological risk forewarning will be refined and enhanced.关键词
