You maybe did that already but what I found interesting as well that along with season changes there is change in air pressure usually as well. I checked out a meteorological webpage that has historical data back to over a decade for the area I live in (tracking even per single day) and looking at the pattern correlating with a cycle starting there is definitely a difference in those years. I.e no cycle last spring, graph is pretty smooth whilst this year pressure jumps around (and I got visited bye the a$$hole right during a heavy drop in Feb this year again)

Sure just one part of many that adds up the chain reaction. (And also nothing anyone of us could influence)
