Frost flower formation occurred during a high-pressure system that caused air temperatures to drop to -30[degrees]C, with relative humidity of 70% (an undersaturated atmosphere), and very calm wind conditions.
Research on frost flower formation has focused on the origin of the water vapour from which they are formed.

Although it's only been operational for a couple of months, we've already got several nice frost flower events, including a really beautiful blossom that lasted about 30 hours," Wang says.
At the University of Manitoba's Sea-ice Environment Research Facility frost flowers can be created under controlled conditions.
Part of Wang's work focuses on the role of frost flowers in so-called 'bromine explosions,' an atmospheric chemistry phenomenon that often follows large Arctic storms in the springtime.

, the delicate crystals that sometimes grow atop fresh sea ice, were revealed as a substantial source of ozone-destroying bromine in the lower atmosphere near the North and South poles (166: 163).

Frost flowers, the delicate crystals that sometimes grow atop fresh sea ice, can be a substantial source of ozone-destroying bromine in the lower atmosphere near the poles, researchers suggest.
The origin of bromine over ice-bound oceans has remained a mystery, but several lines of evidence now point to frost flowers as culprits.
