基于复杂网络模型的沙尘天气空间交互影响研究——以雅鲁藏布江中游为例
Research on Spatial Interaction of Dust Weather Influences Based on Complex Network Model:A Case of the Middle Reaches of the Yarlung Zangbo River
摘要
Abstract
Based on the hourly minimum visibility data from 15 meteorological stations along the middle reaches of the Yarlung Zangbo River during the winter and spring from 2017 to 2020(October to April of the following year),combining the transfer entropy method and theory of complex networks,the regional dust transport matrix was constructe,and the spatial transport and interactive impact characteristics of dust weather were also analyzed.The results indicated that(1)The dust weather system in the mid-reaches of the Yarlung Zangbo River was a resilient network,and the dust events of different weather stations exhibited mutual influences,indicating that dust can be transported across regions.(2)Shenzha,Nanmulin,and Nimu were at the core of the spatial correlation network for dust weather,suggesting these were the main distribution areas of dust.Conversely,Lhasa and Mozhugongka were least affected by other sites.(3)The duration of dust event in the research area was mainly 1 h,followed by 3 h,and the minimum was 6 h,indicating that local dust emission was the main cause and dust could not be transported for a long time.In conclusion,dust weather in the middle reaches of the Yarlung Zangbo River had both local supply and regional transmission,and the stations interacted with each other to form a complex spatial interactive network.Therefore,in order to reduce the impact of dust disasters in the research area,comprehensive coordination and cooperation should be based on governance.关键词
