LIGHTNING STRIKES

Here’s a map of Lightning Strikes. Using data from the Met Office, I wanted to visualise the locations of every lightning strike to hit the UK and Ireland in 2017.

I opted to aggregate the strike locations (all two hundred and eighty thousand) to a 5km hex grid, making it possible to observe patterns in the data. Most strikes in 2017 were concentrated towards the northern and eastern parts of England, as well as a hot spot of activity in Wales.

Using proportional FireFly symbols, I tried to create a sense of realism with glowing electric blue dots.

I also incorporated a chart, showing the number of strikes over time. While no surprise, most strikes occur in the summer months.
