Photographer Jerry Ferguson is the author of these amazing pictures of a “mushroom cloud” that was shaped above Phoenix, in the United States. This natural and weather phenomenon is called a “micro-burst” and occurs when cold air coming from a thunderstorm hit the ground at more than 160km/hour. It gives a fresh powerful and concentrated air current.

Une vidéo en timelapse a également été réalisée par Bryan Snider, montrant ce phénomène depuis le Sky Harbor International Airport du Phoenix.
