Is multiple sclerosis affected by climate?

Although I do already know that ms symptoms worsen when it’s very warm outside, what about humidity, etc? For instance- I moved a month and a half ago to an area that is very dry. It’s a desert, but it’s not warm here at this time of year, just very dry. I ask because my symptoms have tripled since I moved, which may just be fatigue from moving- but it’s been a month and a half now, so I’m looking for other possible reasons- like climate.
