Just a case when lightning rate plot shows large fluctuations (fig 1) but seems to be of little use due the fact that data may not be necessarily showing updraft intensification and area broadening, but mainly a result of cells merging together.  Initially ENI, identifies a rapid jump as the two identified cells are merged into 1, then a quick drop as the cells separate back into two different cells, than another jump as they merge back together (Fig 2 – gif loop).  –Cattywampus
