1)
Mu Radar – 1 megawatt facility in Japan (34°51'14.80"N 136° 6'19.45"E).
2)
Arecibo Observatory – 2 megawatt facility in Puerto Rico (18°20'38.97"N 66°45'9.77"W).
3)
HIPAS – 70 megawatt facility east of Fairbanks, Alaska (64°52'21.18"N 146°50'18.78"W).
4)

5)

I have yet to see any proof that HAARP or related facilities do control/create weather, but there are certainly a lot of scientists and others that would debate that and I don't rule it out as a possibility. Although a lot of research has been shown with the possibility of the types of radio and microwave frequencies these facilities can produce. Here is a declassified
