Mushroom Clouds Over Haarlem, Holland

On the morning of August 16, this ominous mushroom cloud appeared over the sky of Haarlem, Holland. Most meteorologists suggest that it was caused by a temperature inversion, where there is a derision from normal temperature changes in any atmospheric properties with altitude.

Basic temperatures are warmer the closer they get to the ground, colder the higher up they go; however, the warmer temperatures in this cloud are at the top.

Such a wicked visual. Boise, Idaho had a similar incident earlier this month.
