Update – Lightning Maps

Last Wednesday I had a live video on my Facebook and Twitter. If you missed it, you can watch the time-lapse above this blog or go to my Facebook (link) to watch the whole two-hour live video.

During this live video I looked at weather maps of the Netherlands that displayed the lightning strikes that happened between the period of 2004 and 2008. In total I looked and compared 4 places on 500 different lightning maps. The places that I looked at in particular where Breda, Eindhoven, Amsterdam and Groningen.

The result of my research concluded that during the period of 2004 and 2008 those 4 places had a very different lightning ratio. During those 1.461 days there where over 500 days where there where more than 10 lightning strikes in the Netherlands.

The results per city where as followed:

  • Breda: ±120 days
  • Eindhoven: ±74 days
  • Amsterdam: ±58 days
  • Groningen: ±35 days

These differences are very big and to make my hypothesis more convincing, I’m going to test the amount of positive and negative particles in the air in those different places. I will be starting in Breda and hope to expand to different cities very soon.

Update – Lightning spots

Just a small update of what I’m currently working on. I’ve found some interesting reports while doing some location research for the wiring test. I’ve looked at lightning strikes in the Netherlands in May 2004 till 2017, and some peculiar details came up.

I have found out that in these last 13 years, when there where lightning strikes in The Netherlands, they almost always striked near the same places. Why that is the case I’m not really sure. I’ve looked at wind on different levels, humidity, temperature and water currents. But I wasn’t able to pinpoint the exact reason why it happened on those places.

One place got me most interested. From 2004 till 2017 there was a place in The Netherlands that almost never got hit in May. In the north of The Netherlands (Groningen) there is a place that was only hit twice in this period. Even when there where severer thunderstorms near that location, that placed got spared.

To be absolutely sure that it isn’t a coincidence, I’m going to spit through all months from 2004 till 2017 to find out if it is recurring. Because it is a lot of data (5000+ lighting maps), I could use some help! Please send me a message via Twitter / Facebook or email, there will be beer and pizza!
