This is coincident with data coming into point 2. This shows the importance of taking into consideration the area when seeing trends in lightning. In this case, the decrease of lightning was because the cell at point 1 decreased in size and split into a second cell at point 2. This is why a time series began appearing for point 2 at the same time there was a decrease at point 1.<\/p>\n<p>Polarimetric Researcher<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Here is an example with Earth Networks Cell Lightning Cell tracking where a single cell split into two.
