Patterns of climate, lightning fire, and lighting strikes for: A) Avon Park, B) Buffer Preserve, and C) Wade Tract. In the top panel for each study area, temperature and precipitation are plotted using Divisional Data from the National Climatic Data Center (NCDC 2017). Monthly mean temperature is shown as a black curve and monthly mean total precipitation is shown as gray bars. In the bottom panel for each study area, the red curve indicates total lightning fires per month (n) documented by the Florida Forest Service for the county that contains each research study area for the period of record (1981 to 2016). Wade Tract is in Georgia (GA) approximately 16 kilometers north of the state border with Florida (FL), and in that case data from the nearest Florida county were used (Jefferson County). The yellow dashed curves indicate mean daily cloud-to-ground lightning flashes (or strikes) by month for the county that contains each research study area for the period of record (1986 to 2013). Note that precipitation in the top panel and lightning strikes in the bottom panel are plotted on a secondary y-axis.
