This paper studies the correlation between the maximum heights of the Plinian volcanic eruption columns and mass flux of the volcanic eruptions according to measurement data acquired from active volcanoes around the world.
Plinian式火山喷发柱最大高度是研究火山喷发对环境、气候影响时空范围的重要物理学参数,在分析了影响Plinian式火山喷发柱最大高度诸因素的基础上认为,火山喷发的质量通量是反映火山喷发柱最大高度最有效并且在实际中可以进行测量的参数之一,以此为基础,利用目前实测的火山喷发柱最大高度的数值与火山喷发质量通量的结果,建立两者的相关方程为:H=0。
