Zhenhuan Zhou - Frozen

Frozen by Zhenhuan Zhou

Zhenhuan captured this photo showing parts of Niagara Falls covered in ice.

During spells of cold weather, the mist and spray from Niagara Falls can freeze into ice over the top of the rushing water of the waterfall, giving the appearance that the Falls have frozen whilst the water continues to flow underneath the sheets of ice.

However, there are records that the Falls' waters did stop once in March 1848. Strong winds pushed ice from Lake Erie into the mouth of the Niagara River, blocking the channel completely and stopping the water for about 30 hours. The wind then shifted, and the built-up weight of the water broke through the ice, forcing the Niagara River to flow again.

The photograph offers intricate detail of the icicles that have formed around the building and on the rock face. Icicles are hanging tapering pieces of ice that form when the temperature is below freezing. As water drips off the roof or rock, it freezes and becomes suspended in the shape of a droplet. As more water droplets flow over the surface, they freeze on the way down, and so the process continues until an icicle is formed.

Winners will be announced on Thursday, 6 October via RMetS Instagram stories at 6 pm (BST) before being shared on the Royal Meteorological Society's website and other channels.
