I was reading this article about the Nov 2015 Fireball surge. One explanation was that "... gravitational forces from Jupiter causes the Taurid meteor stream to be more heavily concentrated near Earth at certain intervals".
So I got curious of about the statistics of meteorite falls per month. As defined, these are meteorites collected after their fall from space was observed. For the years 1600-2012, there have been about 1100 confirmed cases all over the world. The ones where the month is also known (more than 1050) is charted below:
- With 1-12 as the months, is there an astronomical reason why there should be more meteorite falls (107 cases) starting April? (The Lyrids?)
- Or is it just a sociological reason, meaning it is after winter, and more people are outdoors to observe possible falls? (But then again, the contribution of cases from the Southern Hemisphere, where the seasons are reversed, should even it out.)
Edit: As pointed out by J. Custer in the remarks, the contribution of the Southern hemisphere is relatively meager:
