I'm not sure how related this is to weather, but ive noticed the North magnetic core moving at an increasing speed towards Russia.
Also noticed that our weather seems to becoming more tropical, perhaps like japan with different months for rainy seasons.
Just brainstorming. Not suggesting there is any relation between them but interested.
