Mushroom clouds, forks of lightning, furious thunderstorms and tornado funnels are the apocalyptic images which make up this astonishing set of black and white photographs.
At a glance, this gallery could leave you fearing the world was about to end, but it’s all in a day’s work for fine art photographer Mitch Dobrowner.
Whether he’s capturing monsoons in the desert, pursuing dust storms or creeping up on lightning, Dobrowner, who cites Ansel Adams as his inspiration, makes it his business to bear witness to nature’s fury.
He told Huffington Post UK about the initial experiment which led to the series of photographs before you.
"The 'storm' series started as only an experiment. Though I had done my research beforehand I had no idea what to really expect.
"On the second day out (July 13, 2009) we sat in Sturgis, S.D., watching a storm system form just to our south. It was traveling southeast, so we took off after it. We tracked it through the Badlands, in South Dakota, and down into Valentine, Nebraska, It was a total of a nine-hour, 500 plus mile drive.
"We eventually stopped in a field outside Valentine. When we got out of the van we stood in awe of the sight of a 65,000 foot high, rotating super-cell right in front of us.
"The storm was continuing to build, with intake wind gusts of more than 50 mph. The only way I could describe it in words is – I felt like we were standing next to a 65,000 foot-high vacuum cleaner.
"Its formation had an ominous presence and power that I had never witnessed or experienced before in my life. I remember turning to Roger Hill (my guide) who was standing next to me, and saying in the howling winds, 'What the..! You have got to be kidding me.' It was only the second day of my 'experiment', but I knew then that this 'experiment' had just become a project."
Dobrowner’s work will be featured in the July edition of National Geographic’s iPad magazine.
