Ulan Bator Naled Ice Shield

Yolin Am natural Naled ice shield

Artificial naled ice shield is a novel invention to combat global warming.

One of the most popular tourist attractions in Mongolia is the frozen ice in the Yolin Am canyon deep in the Gobi desert. The ice remains frozen throughout the hot Gobi summer.
These ice slabs are named by scientists Naled ice shields.

This unique natural phenomena has inspired a novel invention proposed by Robin a geologist residing in Mongolia. The idea is to create artificially such an ice slab near Ulan Bator during the freezing winter, and let it melt slowly during the hot summer. The ice will have an environmental impact on the micro climate around Ulan Bator, the same way it does in the Gobi desert.

The goal is to combat global warming with the help of mother nature. Ulan Bator is allegedly the coldest capital in the world. Temperatures drop down to -30 degrees Celsius during winter and rise up to +30 during summer. Harnessing the natural winter "freezer" to create a "natural" air conditioner for the city during summer.

The river Tuul runs alongside Ulan Bator. During winter the river freezes. In spring the ice breaks up.
To create a large ice slab that will remain throughout the summer, one has to imitate the way nature creates these naled ice shields in the Gobi desert..
The first to observe
He noticed that when a thin layer of water runs over ice and freezes during the night it creates a thin layer of ice. The next day another thin layer of water covers the ice and freezes. This creates a large slab of layers of ice which he named in Russion Naled. Robin in his research proposed to name it Naled Ice Shields.
Unlike rivers and lakes where freezing occures only on the top layer, while leaving the lower levels of water unfrozen, in a naled ice shield layers of frozen ice are created layer by layer bottom up, creating a solid frozen ice slab.



Following is an artist illustration of an artificial naled ice shield on the Tuul river near Ulan Bator. The rolling winds coming down the mountain will chill when passing by the naled ice shield and continue towards the city dropping the local summer temperatures by 2-3 degrees, similar to the breeze coming from the sea towards cities residing near a sea.

Do you know where the ice shield is along the Tuul river?

Hi

I am not sure the experiment has started yet.
