These are interesting articles, and underscore that every brain is different. This is why it seems difficult for researchers to find a common weather cause, because it varies so much among people. Some are affected by hot weather, some by humid, some by low pressure. Some are even opposite - affected by cold, or by dry conditions. When researchers lump these people into a study group, the triggers cancel each other out, and the conclusions are unclear. For me the culprit is changing pressure, either up or down. Since this is more stable in the summer, I do a lot better, where someone affected by heat or humidity might do more poorly in the same season.

I am submitting my 5 years of data to a research student this week, and am hoping that it can lead to more answers in this area.
